I've got a google webmasters tool account with a website I help look after, they've employed the services of an SEO/SEM company* who have asked to add google/microsoft/yahoo webmasters tools accounts
I don't want to give them access to my account (its tied in with other websites I have on webmasters tools) so my question is it ok/possible to have multiple webmaster tools accounts on a website?
*The company are trustworthy, they've been great to deal with.
Yes, you can. A site can have multiple owners. You don't need to give access to your account, each owner can have its own account and verify it against the site.
See Multiple Users.
A site can have more than one verified owner, and you can add and remove owners easily using the Manage Verification page. (Note: To add a person as a user, that person must have a valid Google Account—for example, a Gmail account.) These owners will have all the same rights as the original owner, including the ability to add and remove owners.
Yes, it's possible to have multiple users for one Webmaster Tools account. The SEO company needs to have its own account, then add the site in question.
They will get a verification code or file - they can send this to you to add to the site. Now they will become verified owners and can see all the same stats you do.
