Trying to work on both my actual "work" repos, and my repos on git hub, from my computer.
The work account was set up first, and everything works flawlessly.
My account, however, cannot seem to push to my repo, which is set up under a different account/email.
I've tried copying my work key up to my account, but that throws an error because of course a key can be only attached to one account.
How can I push/pull to and from both accounts from their respective GitHub credentials?
All you need to do is configure your SSH setup with multiple SSH keypairs.
This link is easy to follow (Thanks Eric):
Generating SSH keys (Win/msysgit):
Relevant steps from the first link:
Generate an SSH-key:
ssh-keygen -t ed25519 -C "john@doe.example.com"
Follow the prompts and decide a name, e.g. id_ed25519_example_company.
Copy the SSH public-key to GitHub from ~/.ssh/id_ed25519_doe_company.pub and tell ssh about the key:
ssh-add ~/.ssh/id_ed25519_doe_company
Create a config file in ~/.ssh with the following contents:
Host github-doe-company
HostName github.com
User git
IdentityFile ~/.ssh/id_ed25519_doe_company
Add your remote:
git remote add origin git@github-doe-company:username/repo.git
or change using:
git remote set-url origin git@github-doe-company:username/repo.git
Also, if you're working with multiple repositories using different personas, you need to make sure that your individual repositories have the user settings overridden accordingly:
Setting user name, email and GitHub token – Overriding settings for individual repos https://help.github.com/articles/setting-your-commit-email-address-in-git/
Hope this helps.
Note:
Some of you may require different emails to be used for different repositories, from git 2.13 you can set the email on a directory basis by editing the global config file found at: ~/.gitconfig using conditionals like so:
[user]
name = Pavan Kataria
email = defaultemail@example.com
[includeIf "gitdir:~/work/"]
path = ~/work/.gitconfig
And then your work specific config ~/work/.gitconfig would look like this:
[user]
email = pavan.kataria@example.com
Thank you @alexg for informing me of this in the comments.
Use HTTPS:
change remote url to https:
git remote set-url origin https://USERNAME@github.com/USERNAME/PROJECTNAME.git
and you are good to go:
git push
To ensure that the commits appear as performed by USERNAME, one can setup the user.name and user.email for this project, too:
git config user.name USERNAME
git config user.email USERNAME@example.com
Getting into shape
To manage a git repo under a separate github/bitbucket/whatever account, you simply need to generate a new SSH key.
But before we can start pushing/pulling repos with your second identity, we gotta get you into shape – Let's assume your system is setup with a typical id_rsa and id_rsa.pub key pair. Right now your tree ~/.ssh looks like this
$ tree ~/.ssh
/Users/you/.ssh
├── known_hosts
├── id_rsa
└── id_rsa.pub
First, name that key pair – adding a descriptive name will help you remember which key is used for which user/remote
# change to your ~/.ssh directory
$ cd ~/.ssh
# rename the private key
$ mv id_rsa github-mainuser
# rename the public key
$ mv id_rsa.pub github-mainuser.pub
Next, let's generate a new key pair – here I'll name the new key github-otheruser
$ ssh-keygen -t rsa -b 4096 -f ~/.ssh/github-otheruser
Now, when we look at tree ~/.ssh we see
$ tree ~/.ssh
/Users/you/.ssh
├── known_hosts
├── github-mainuser
├── github-mainuser.pub
├── github-otheruser
└── github-otheruser.pub
Next, we need to setup a ~/.ssh/config file that will define our key configurations. We'll create it with the proper owner-read/write-only permissions
$ (umask 077; touch ~/.ssh/config)
Open that with your favourite editor, and add the following contents
Host github.com
User git
IdentityFile ~/.ssh/github-mainuser
Host github.com-otheruser
HostName github.com
User git
IdentityFile ~/.ssh/github-otheruserPresumably, you'll have some existing repos associated with your primary github identity. For that reason, the "default" github.com Host is setup to use your mainuser key. If you don't want to favour one account over another, I'll show you how to update existing repos on your system to use an updated ssh configuration.
Add your new SSH key to github
Head over to github.com/settings/keys to add your new public key
You can get the public key contents using: copy/paste it to github
$ cat ~/.ssh/github-otheruser.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQDBVvWNQ2nO5...
Now your new user identity is all setup – below we'll show you how to use it.
Getting stuff done: cloning a repo
So how does this come together to work with git and github? Well because you can't have a chicken without and egg, we'll look at cloning an existing repo. This situation might apply to you if you have a new github account for your workplace and you were added to a company project.
Let's say github.com/someorg/somerepo already exists and you were added to it – cloning is as easy as
$ git clone github.com-otheruser:someorg/somerepo.gitThat bolded portion must match the Host name we setup in your ~/.ssh/config file. That correctly connects git to the corresponding IdentityFile and properly authenticates you with github
Getting stuff done: creating a new repo
Well because you can't have a chicken without and egg, we'll look at publishing a new repo on your secondary account. This situation applies to users that are create new content using their secondary github account.
Let's assume you've already done a little work locally and you're now ready to push to github. You can follow along with me if you'd like
$ cd ~
$ mkdir somerepo
$ cd somerepo
$ git init
Now configure this repo to use your identity
$ git config user.name "Mister Manager"
$ git config user.email "someuser@some.org"
Now make your first commit
$ echo "hello world" > readme
$ git add .
$ git commit -m "first commit"
Check the commit to see your new identity was used using git log
$ git log --pretty="%H %an <%ae>"
f397a7cfbf55d44ffdf87aa24974f0a5001e1921 Mister Manager <someuser@some.org>
Alright, time to push to github! Since github doesn't know about our new repo yet, first go to github.com/new and create your new repo – name it somerepo
Now, to configure your repo to "talk" to github using the correct identity/credentials, we have add a remote. Assuming your github username for your new account is someuser ...
$ git remote add origin github.com-otheruser:someuser/somerepo.gitThat bolded portion is absolutely critical and it must match the Host that we defined in your ~/.ssh/config file
Lastly, push the repo
$ git push origin master
Update an existing repo to use a new SSH configuration
Say you already have some repo cloned, but now you want to use a new SSH configuration. In the example above, we kept your existing repos in tact by assigning your previous id_rsa/id_rsa.pub key pair to Host github.com in your SSH config file. There's nothing wrong with this, but I have at least 5 github configurations now and I don't like thinking of one of them as the "default" configuration – I'd rather be explicit about each one.
Before we had this
Host github.com
User git
IdentityFile ~/.ssh/github-mainuser
Host github.com-otheruser
HostName github.com
User git
IdentityFile ~/.ssh/github-otheruser
So we will now update that to this (changes in bold)
Host github.com-mainuser
HostName github.com
User git
IdentityFile ~/.ssh/github-mainuser
Host github.com-otheruser
HostName github.com
User git
IdentityFile ~/.ssh/github-otheruserBut now any existing repo with a github.com remote will not work with this identity file. But don't worry, it's a simple fix.
To update any existing repo to use your new SSH configuration, update the repo's remote origin field using set-url -
$ cd existingrepo
$ git remote set-url origin github.com-mainuser:someuser/existingrepo.git
That's it. Now you can push/pull to your heart's content
SSH key file permissions
If you're running into trouble with your public keys not working correctly, SSH is quite strict on the file permissions allowed on your ~/.ssh directory and corresponding key files
As a rule of thumb, any directories should be 700 and any files should be 600 - this means they are owner-read/write-only – no other group/user can read/write them
$ chmod 700 ~/.ssh
$ chmod 600 ~/.ssh/config
$ chmod 600 ~/.ssh/github-mainuser
$ chmod 600 ~/.ssh/github-mainuser.pub
$ chmod 600 ~/.ssh/github-otheruser
$ chmod 600 ~/.ssh/github-otheruser.pub
How I manage my SSH keys
I manage separate SSH keys for every host I connect to, such that if any one key is ever compromised, I don't have to update keys on every other place I've used that key. This is like when you get that notification from Adobe that 150 million of their users' information was stolen – now you have to cancel that credit card and update every service that depends on it – what a nuisance.
Here's what my ~/.ssh directory looks like: I have one .pem key for each user, in a folder for each domain I connect to. I use .pem keys to so I only need one file per key.
$ tree ~/.ssh
/Users/myuser/.ssh
├── another.site
│ ├── myuser.pem
├── config
├── github.com
│ ├── myuser.pem
│ ├── someusername.pem
├── known_hosts
├── somedomain.com
│ ├── someuser.pem
└── someotherdomain.org
└── root.pem
And here's my corresponding /.ssh/config file – obviously the github stuff is relevant to answering this question about github, but this answer aims to equip you with the knowledge to manage your ssh identities on any number of services/machines.
Host another.site
User muyuser
IdentityFile ~/.ssh/another.site/muyuser.pem
Host github.com-myuser
HostName github.com
User git
IdentityFile ~/.ssh/github.com/myuser.pem
Host github.com-someuser
HostName github.com
User git
IdentityFile ~/.ssh/github.com/someusername.pem
Host somedomain.com
HostName 162.10.20.30
User someuser
IdentityFile ~/.ssh/somedomain.com/someuser.pem
Host someotherdomain.org
User someuser
IdentityFile ~/.ssh/someotherdomain.org/root.pem
Getting your SSH public key from a PEM key
Above you noticed that I only have one file for each key. When I need to provide a public key, I simply generate it as needed.
So when github asks for your ssh public key, run this command to output the public key to stdout – copy/paste where needed
$ ssh-keygen -y -f someuser.pem
ssh-rsa AAAAB3NzaC1yc2EAAAA...
Note, this is also the same process I use for adding my key to any remote machine. The ssh-rsa AAAA... value is copied to the remote's ~/.ssh/authorized_keys file
Converting your id_rsa/id_rsa.pub key pairs to PEM format
So you want to tame you key files and cut down on some file system cruft? Converting your key pair to a single PEM is easy
$ cd ~/.ssh
$ openssl rsa -in id_rsa -outform pem > id_rsa.pem
Or, following along with our examples above, we renamed id_rsa -> github-mainuser and id_rsa.pub -> github-mainuser.pub – so
$ cd ~/.ssh
$ openssl rsa -in github-mainuser -outform pem > github-mainuser.pem
Now just to make sure that we've converted this correct, you will want to verify that the generated public key matches your old public key
# display the public key
$ cat github-mainuser.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAA ... R++Nu+wDj7tCQ==
# generate public key from your new PEM
$ ssh-keygen -y -f someuser.pem
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAA ... R++Nu+wDj7tCQ==
Now that you have your github-mainuser.pem file, you can safely delete your old github-mainuser and github-mainuser.pub files – only the PEM file is necessary; just generate the public key whenever you need it ^_^
Creating PEM keys from scratch
You don't need to create the private/public key pair and then convert to a single PEM key. You can create the PEM key directly.
Let's create a newuser.pem
$ openssl genrsa -out ~/.ssh/newuser.pem 4096
Getting the SSH public key is the same
$ ssh-keygen -y -f ~/.ssh/newuser.pem
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACA ... FUNZvoKPRQ==
By creating different host aliases to github.com in your ~/.ssh/config, and giving each host alias its own ssh key, you can easily use multiple github accounts without confusion. That’s because github.com distinguishes not by user, which is always just git, but by the ssh key you used to connect. Just configure your remote origins using your own host aliases.”
The above summary is courtesy of comments on the blog post below.
I've found this explanation the clearest. And it works for me, at least as of April 2012.
http://net.tutsplus.com/tutorials/tools-and-tips/how-to-work-with-github-and-multiple-accounts/
The details at http://net.tutsplus.com/tutorials/tools-and-tips/how-to-work-with-github-and-multiple-accounts/ linked to by mishaba work very well for me.
From that page:
$ touch ~/.ssh/config
Then edit that file to be something like this (one entry per account):
#Default GitHub
Host github.com
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa
Host github-COMPANY
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_COMPANY
Open config file & add below codes. (change according to your account)
Account 1
# account_1
Host gitlab.com-account_1
HostName gitlab.com
User git
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_account_1
Account 2
# Account2
Host gitlab.com-Account2
HostName gitlab.com
User git
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_Account2
Account 3
# Account_3
Host github.com-Account3
HostName github.com
User git
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_Account_3
Add remote url as follows
Account 1
git remote add origin git@gitlab.com-account_1:group_name/repo_name.git
Account 2
git remote add origin git@gitlab.com-Account2:group_name/repo_name.git
Account 3
git remote add origin github.com-Account3:github_username/repo_name.git
Make sure that IdentityFile names are same as you created during ssh key generation.
This answer is for beginners (none-git gurus). I recently had this problem and maybe its just me but most of the answers seemed to require rather advance understanding of git. After reading several stack overflow answers including this thread, here are the steps I needed to take in order to easily switch between GitHub accounts (e.g. assume two GitHub accounts, github.com/personal and gitHub.com/work):
ls -al ~/.ssh .pub are your ssh keys so you should have two for the personal and work accounts. If there is only one or none, its time to generate other wise skip this.ssh-keygen -t rsa -C "the copied email", you'll see:/.../.ssh/id_rsa_work if generating for work account. provide a password or just enter to ignore and, you'll read something like The key's randomart image is: and the image. done.ls -al ~/.ssh again.pbcopy < ~/.ssh/id_rsa_work.pub, replace id_rsa_work.pub with what you called yours.id_rsa_work] and navigate toEdit the global git configuration: Last step is to make sure the global configuration file is aware of all github accounts (so to say).
Run git config --global --edit to edit this global file, if this opens vim and you don't know how to use it, press i to enter Insert mode, edit the file as below, and press esc followed by :wq to exit insert mode:
[inside this square brackets give a name to the followed acc.]
name = github_username
email = github_emailaddress
[any other name]
name = github_username
email = github_email
[credential]
helper = osxkeychain
useHttpPath = true
Done!, now when trying to push or pull from a repo, you'll be asked which GitHub account should be linked with this repo and its asked only once, the local configuration will remember this link and not the global configuration so you can work on different repos that are linked with different accounts without having to edit global configuration each time.
In my case, I have my work account in Git-Lab and my personal account in GitHub. My Git-Lab account was configured globally to be accessed from all directories in my laptop like this:
git config --global user.name WORK_USERNAME
git config --global user.email WORK_USERNAME@example.com
So if you're looking for a solution without using SSL, you can do it by using git init in an empty folder, and then insert your personal account credentials in that folder:
git config user.name PERSONAL_USERNAME
git config user.email PERSONAL_USERNAME@example.com
Notice here --global is not set, because you only want your personal git to be accessed from there and not everywhere, so whatever inside that folder will have its git credentials connected to your personal account and outside of it will be connected to your work account.
After that, you can clone your repository like so git clone your_repo_link.git. Then a new window will popup and ask you to login with your github account.
To verify your process try git config --list inside the folder that you created, you should see both work and personal usernames and emails with their directories.
Outside that folder, if you run git config --list you should see your work username and email only.
That's it, hope this helps someone without configuring SSL.
I use shell scripts to switch me to whatever account I want to be "active". Essentially you start from a fresh start, get one account configured properly and working, then move the these files to a name with the proper prefix. From then on you can use the command "github", or "gitxyz" to switch:
# my github script
cd ~/.ssh
if [ -f git_dhoerl -a -f git_dhoerl.pub -a -f config_dhoerl ]
then
;
else
echo "Error: missing new files"
exit 1
fi
# Save a copy in /tmp, just in case
cp id_rsa /tmp
cp id_rsa.pub /tmp
cp config /tmp
echo "Saved old files in /tmp, just in case"
rm id_rsa
rm id_rsa.pub
rm config
echo "Removed current links/files"
ln git_dhoerl id_rsa
ln git_dhoerl.pub id_rsa.pub
ln config_dhoerl config
git config --global user.email "dhoerl@<company>.com"
git config --global github.user "dhoerl"
git config --global github.token "whatever_it_is"
ssh-add -D
I've had great luck with this. I also created a run script in Xcode (for you Mac users) so it would not build my project unless I had the proper setting (since its using git):
Run Script placed after Dependencies (using /bin/ksh as the shell):
if [ "$(git config --global --get user.email)" != "dhoerl@<company>.com" ]
then
exit 1
fi
EDIT: added tests for new files existence and copying old files to /tmp to address comment by @naomik below.
just figured this out for Windows, using credentials for each repo:
cd c:\User1\SomeRepo
git config --local credential.https://github.com.user1 user1
git config --local credential.useHttpPath true
git config --local credential.helper manager
git remote set-url origin https://USERNAME@github.com/USERNAME/PROJECTNAME.git
The format of credential.https://github.com. tells the credential helper the URL for the credential. The 'useHttpPath' tells the credential manager to use the path for the credential. If useHttpPath is omitted then the credential manager will store one credential for https://github.com. If it is included then the credential manager will store multiple credentials, which is what I really wanted.
Simpler and Easy fix to avoid confusion..
For Windows users to use multiple or different git accounts for different projects.
Following steps:
Go Control Panel and Search for Credential Manager.
Then Go to Credential Manager -> Windows Credentials
Now remove the git:https//github.com node under Generic Credentials Heading
This will remove the current credentials. Now you can add any project through git pull it will ask for username and password.
When you face any issue with other account do the same process.
There are plenty of answers explaining how to accomplish what you have asked but I'd like to offer a different perspective.
I think there's something to be said for keeping work and personal stuff separate from each other. It's pretty trivial to switch between user accounts on all operating systems so you could just create separate OS accounts for work and play and have different github accounts logged in in each.
Maintaining a clear separation of concerns can also...
In case you don't want to mess with the ~/.ssh/config file mentioned here, you could instead run git config core.sshCommand "ssh -i ~/.ssh/custom_id_rsa" in the repo where you want to commit from a different account.
The rest of the setup is the same:
Create a new SSH key for the second account with ssh-keygen -t rsa -f ~/.ssh -f ~/.ssh/custom_id_rsa
Sign in to github with your other account, go to https://github.com/settings/keys , and paste the contents of ~/.ssh/custom_id_rsa.pub
Make sure you're using SSH instead of HTTPS as remote url: git remote set-url origin git@github.com:upstream_project_teamname/upstream_project.git
Beside of creating multiple SSH Keys for multiple accounts you can also consider to add collaborators on each project using the same account emails and store the password permanently.
#this store the password permanently
$ git config --global credential.helper wincred
I have setup multiple accounts with different emails then put the same user and email on each account as one of the collaborators. By this way I can access to all account without adding SSH Key, or switching to another username, and email for the authentication.
I see a lot of possible workarounds here. As a quick fix, @Greg's one seems relatively easy. However, it's best to set up separate ssh keys for all different accounts in the long run. This video demonstrates it briefly. Here are the steps mentioned in that video blog.
Step 1 - Create a New SSH Key for a new account and save it in a separate file (e.g. ~/.ssh/id_rsa_new_account_name), not in the original file i.e. ~/.ssh/id_rsa
ssh-keygen -t rsa -C "your-email-address"
Step 2 - Attach the New Key
Account Overview, and attach the new key ~/.ssh/id_rsa_new_account_name.pub within the SSH Public Keys section.ssh-add ~/.ssh/id_rsa_new_account_name. If successful, you'll see a response of Identity Added.Step 3 - Create a Config File
touch ~/.ssh/config
And save the following contents into the file
#Default GitHub
Host github.com
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa
#New Account
Host github-new-account-name
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_new_account_name
Step 4 - Try it Out Now every time you want to use the new account and the associated repo, type this for the respective repo
git remote add origin git@github-new-account-name:your-domain.com/your-repo.git
I found this gem to be very useful: sshwitch
https://github.com/agush22/sshwitch
http://rubygems.org/gems/sshwitch
It helps to switch out ssh keys. Remember to back up everything first!
Also to make sure that commits have the correct email address associated with them, I made sure that the ~/.gitconfig file had the proper email address.
another easier way is using multiple desktop apps, like what i am doing, using account A on Github desktop, while using account B on Github Kraken
The easiest and straightforward approach (IMHO) - no config files not too much hassle
Just create another ssh key.
Let's say you have aa new work GitHub account, just create a new key for it:
sh-keygen -t rsa -C "email@work_mail.com" -f "id_rsa_work_user1"`
Now you should have the old one and the new one, to see them, run:
ls -al ~/.ssh
You need to run the above only once.
From now on, every time you want to switch between the two, just run:
ssh-add -D
ssh-add ~/.ssh/id_rsa_work_user1 #make to use this without the suffix .pub
In order the switch to the old one, run again:
ssh-add -D
ssh-add ~/.ssh/<previous id_rsa>
Got my private repo working using SSH key pairs. This was tested on git for Windows.
ssh-keygen -t ed25519 -C "your_email@example.com"eval $(ssh-agent)ssh-add ~/.ssh/id_ed25519clip < ~/.ssh/id_ed25519.pubssh -T git@github.comgit config user.email your_email@example.com
git config user.name github_username
git remote -v
git remote set-url origin git@github.com:github_username/your-repo-name.git
git remote show origin
IntelliJ Idea has built-in support of that https://www.jetbrains.com/help/idea/github.html#da8d32ae
.gitconfig using a personal access tokenIf you do not want to modify your host file, use SSH keys, or setup a .gitconfig for each repo, then you may use a personal .gitconfig that you basically include from the root level config. Given an OSX directory structure like
# root level git config
~/.gitconfig
# your personal repos under some folder like
../personal/
../home/
~/Dropbox/
Add a .gitconfig in your personal folder, such as ~/Dropbox/.gitconfig
[user]
email = first.last@home.com
name = First Last
[credential]
username = PersonalGithubUsername
helper = osxkeychain
In your root level .gitconfig add an includeIf section to source your personal config whenever you are in your personal directory. Any settings there will override the root config as long as the includeIf comes after the settings you want to override.
[user]
email = first.last@work.com
name = "First Last"
[credential]
helper = osxkeychain
[includeIf "gitdir:~/Dropbox/**"]
path = ~/Dropbox/.gitconfig
Try pushing to your personal repo or pulling from your private repo
git push
# prompts for password
When prompted enter either your personal password or, better yet, your personal access token that you have created in your account developer settings. Enter that token as your password.
Assuming you are already using git-credential-osxkeychain, your personal credentials should be stored in your keychain, so two github entries will show up, but with different accounts.
Option 0: you dont want to mess around with OS settings.. you just want to commit to a different github account with a different public key for one repo.
solution:
create the new key: ssh-keygen -t rsa -b 4096 -f ~/.ssh/alt_rsa
add the key to the keyset: ssh-add -K ~/.ssh/alt_rsa
copy and add the pub key to the github account: (see github instructions)
test the key with github: ssh -i ~/.ssh/alt_rsa T git@github.com
clone the repo using the git protocol (not HTTP): git clone git@github:myaccount...
in the cloned repo:
git config core.sshCommand "ssh -i ~/.ssh/alt_rsa -F /dev/null"
git config user.name [myaccount]
git config user.email [myaccount email]
now you should be able to git push correctly without interferring with your everyday git account
Manage multiple GitHub accounts on one Windows machine (HTTPS)
Let's say you previously use git on your machine and configure git global config file. To check it open the terminal and :
git config --global -e
It opens your editor, and you may see something like this:
[user]
email = yourEmail@gmail.com
name = Your_Name
...
And this is great because you can push your code to GitHub account without entering credentials every time. But what if it needs to push to repo from another account? In this case, git will reject with 403 err, and you must change your global git credentials. To make this comfortable lat set storing a repo name in a credential manager:
git config --global credential.github.com.useHttpPath true
to check it open config one more time git config --global -e you will see new config lines
[credential]
useHttpPath = true
...
The is it. Now when you first time push to any account you will see a pop-up Screenshot_1
Enter specific for this repo account credentials, and this will "bind" this account for the repo. And so in your machine, you can specify as many accounts/repos as you want.
For a more expanded explanation you can see this cool video that I found on youtube: https://youtu.be/2MGGJtTH0bQ
Just change the user.name & user.email locally in the repo. to the ones you want to push to that repo with.
Example: I have a work account in gitlab having a project. After cloning this project/repo, in the terminal, I type out:
git config user.name "my-work-username"
git config user.email "my-work-email-id"
Now, say I've another personal project/repo in Gitlab that I want to associate with my personal account. Just like above, after cloning, I type:
git config user.name "my-personal-username"
git config user.email "my-personal-email-id"
Hope this helps. Upvote if it worked for you! :)
Use docker!
This may not be suitable for everyone but this is what I ended up doing for myself.
All my developments are now done inside docker containers. I am a vim user but I know VSCode has plugin to work with docker containers.
So since I have different docker containers for different projects/languages, I can use different git configurations inside each. Problem solved.
just add this line in your fav editor and you are done for life
git remote set-url origin https://user-token-of-particular-user@github.com/profile-name/repo-name
Unlike other answers, where you need to follow few steps to use two different github account from same machine, for me it worked in two steps.
You just need to :
1) generate SSH public and private key pair for each of your account under ~/.ssh location with different names and
2) add the generated public keys to the respective account under Settings >> SSH and GPG keys >> New SSH Key.
To generate the SSH public and private key pairs use following command:
cd ~/.ssh
ssh-keygen -t rsa -C "email@work.com" -f "id_rsa_WORK"
ssh-keygen -t rsa -C "email@gmail.com" -f "id_rsa_PERSONAL"
As a result of above commands, id_rsa_WORK and id_rsa_WORK.pub files will be created for your work account (ex - git.work.com) and id_rsa_PERSONAL and id_rsa_PERSONAL.pub will be created for your personal account (ex - github.com).
Once created, copy the content from each public (*.pub) file and do Step 2 for the each account.
PS : Its not necessary to make an host entry for each git account under ~/.ssh/config file as mentioned in other answers, if hostname of your two accounts are different.
You should and must not push to the project with some common credentials. Once starting on a new machine use the following steps to setup and use correctly your gitlab credentials:
All this as follows:
# create the public / private key credentials on that specific machine
ssh-keygen -t rsa -b 4096 -C "<<you>>@org.net" -f ~/.ssh/id_rsa.<<you>>.`hostname -s`
# setup your public key in the gitlab ui
cat ~/.ssh/id_rsa.<<you>>.`hostname -s`
# make sure you clone the repo via the git and not http url
git clone git@git.in.org.net:org/some-repo.git
# set the git alias to avoid constant typing of the repeating prefix to the git cmd
alias git='GIT_SSH_COMMAND="ssh -i ~/.ssh/id_rsa.<<you>>.`hostname -s`" git'
# during git commit ALWAYS use the author and e-mail flags
git add --all ; git commit -nm "$git_msg" --author "YourFirstName YourLastName <you@phz.fi>"
# use git as normal
git fetch --all; git pull --all
Create a new SSH key in your terminal/command line.
ssh-keygen -t rsa -C “your-email-address”
The following will then show:
Generating public/private rsa key pair. Enter file in which to save the key (/home/your_username/.ssh/id_rsa):
Copy and paste the path followed by an identifiable name for the file:
/home/your_username/.ssh/id_rsa_personal
4) It will then ask you for the following:
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
5) You can now type in the following command to see all the SSH keys you have on your local machine:
ls -al ~/.ssh
You should be able to see your new SSH key file. As you can see in my one I have both id_rsa_test and id_rsa_personal.pub.
drwx------ 2 gmadmin gmadmin 4096 Nov 16 22:20 .
drwxr-xr-x 42 gmadmin gmadmin 4096 Nov 16 21:03 ..
-rw------- 1 gmadmin gmadmin 1766 Nov 16 22:20 id_rsa_personal
-rw-r--r-- 1 gmadmin gmadmin 414 Nov 16 22:20 id_rsa_personal.pub
-rw-r--r-- 1 gmadmin gmadmin 444 Nov 6 11:32 known_hosts
6) Next you need to copy the SSH key which is stored in id_rsa_personal.pub file. You can open this in text editor of your choice. I am currently using atom so I opened the file using the following command:
atom ~/.ssh/id_rsa_personal.pub
You will then get something similar to this:
ssh-rsa AAB3HKJLKC1yc2EAAAADAQABAAABAQCgU5+ELtwsKkmcoeF3hNd7d6CjW+dWut83R/Dc01E/YzLc5ZFri18doOwuQoeTPpmIRVDGuQQsZshjDrTkFy8rwKWMlXl7va5olnGICcpg4qydEtsW+MELDmayW1HHsi2xHMMGHlNv
7) Copy this and navigate to your GitHub account → Settings → SSH and GPG keys 8) Click on New SSH key. Copy the key, give it a title and add it. 9) Add key from terminal
ssh-add ~/.ssh/id_rsa_personal
Enter passphrase for /home/your_username/.ssh/id_rsa_personal:
10) Configure user and password.
git config --global user.name "gitusername"
git config --global user.email "gitemail"
11) We are ready to commit and push now.
git init
git add .
git commit
git push
If you have created or cloned another repository and you were not able to pull from origin or upstream adding the ssh key at that directory using the following command worked.
This is the error I was getting here:
Warning: Permanently added the RSA host key for IP address '61:fd9b::8c52:7203' to the list of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I used the following command, this works:
ssh-add ~/.ssh/id_rsa_YOUR_COMPANY_NAME
Change the authentication method in github from SSh to HTTP. This way it will not care if you are logged with your work github account and you try to remotely interact with your personal github account (which has different credentials than the ones you are currently logged with onto your local machine).
There could be multiple way to do it but Following solution works for me and very simple. I am not trying to do it with SSH, my steps and solution is based on HTTPS.
Create your project DIR on your local machine. Example d:\test_git_multiple_account
go to the folder "test_git_multiple_account"
Add few files here into the DIR
Open Git bash here and run following command
a. git init // initialization
b. git add , // add
c. git commit -m "initial commit"
you will get following output : in my case i use to add one python file created
from code.
**[master (root-commit) d4defd9] initial commit
2 files changed, 4 insertions(+)
create mode 100644 .vscode/settings.json
create mode 100644 Hello.py**
d. git remote add origin <HTTPS repo link>
e. git remote -v // check the repo version
f. git push origin master
it will ask your git hub user name and password via popup screen.
you will get the following output

remote: Create a pull request for 'master' on GitHub by visiting:
remote: https://github.com/vishvadeepaktripathi/Hello_Py/pull/new/master
remote:
To https://github.com/vishvadeepaktripathi/Hello_Py.git
* [new branch] master -> master
This will create new branch as i named here called master. You can commit into main branch once you change the branch in this case your existing file will be delete. So i would recommend that to checkout into main branch into First step then proceed for every command in case you want to checkout directly into main branch. Caution At the First login it might give you an error message and ask again for login and password and then it will publish your change into Git hub.
Once this is done you will get message to new pull request into your github account. you can merge your changes from master branch to the main branch.
i created master branch here you named your branch as per your choice. Attaching the screen shot as well. enter image description here
You do not have to maintain two different accounts for personal and work. In fact, Github Recommends you maintain a single account and helps you merge both.
Follow the below link to merge if you decide there is no need to maintain multiple accounts.
https://help.github.com/articles/merging-multiple-user-accounts/
Instead you just add your new email id to your personal git account. This way you don't need to add another SSH key. Just configure your new email by doing git config --global user.email newemail. Then you will be able to clone that repo.
`ssh-add ~/.ssh/id_rsa_COMPANY `
to tell the ssh-agent to include it for use.
Rest works fine for me with the above mentioned tutorial. – Brut3e May 24 '13 at 05:09
