How to setup Monero RPC authentication?

Question

I am currently experimenting on testnet.

server a = monero wallet
server b = website

I have the monerod client synced. I run the monerod and monero-wallet-rpc on server a. I want to make my commands from server b. monero rpc command

./monero-wallet-rpc  --wallet-file testwallet --password test --rpc-bind-port 28080 --daemon-address 127.0.0.1:28081 --testnet --daemon-login test:test

monerod command

./monerod  --rpc-login test:test --testnet --rpc-bind-ip=127.0.0.1 --log-level=1

It gets stuck at

2018-02-01 22:42:51.060     7f577a44b780        INFO    global  contrib/epee/include/net/http_server_impl_base.h:76      Binding on 127.0.0.1:28080
2018-02-01 22:42:51.060     7f577a44b780        WARN    wallet.rpc      src/wallet/wallet_rpc_server.cpp:2945    Starting wallet rpc server

Any attempts to contact the RPC server from server b results in 401 unauthorized. When I start the monero-wallet-cli it works well.

Do you want to access monerod RPC or monero-wallet-cli RPC (or both)? — user36303, Feb 01 '18 at 22:58
Just the rpc. The wallet-cli works fine and all commands work — Anekdotin, Feb 01 '18 at 23:01
The monerod says "synchonized ok" and seems fine with testnet blockchain. I also built it from source using git pull yesterday — Anekdotin, Feb 01 '18 at 23:03
apparently with running log level=4 on the rpc, it shows the balance, and the 401 when i issue a command — Anekdotin, Feb 01 '18 at 23:12
Add the --disable-rpc-login to monero rpc command in order to disable the login. 401 http error is UNAUTHORIZED error. — SerHack, Feb 02 '18 at 13:46

401 HTTP error is defined as UNAUTHORIZED error meaning you don't have the permission to call the RPC API.

At the moment, Monero Wallet RPC requires authentication by default, username is: monero , password is a randomly generated string.

To disable the login: add the --disable-rpc-login flag to the command line.

If you want to specify a username and a password, add the --rpc-login username:password where username is your username and password is your password.

I had to explicitly specify digest authentication to get past this with curl

curl -u monero:APASSWORD --digest -X POST http://127.0.0.1:42069/json_rpc '{"jsonrpc":"2.0","method":"getaddress","params": null,"id":"11111"}'

It seem like you have started the RPC correctly. Usually the RPC just stops at 'Starting wallet rpc wallet server' You are getting 401 because you might not be using using digest auth. You need to provdide the credentials used with --rpc-login rpc_username:rpc_password like this - curl -u rpc_username:rpc_password --digest -X POST.....
