What does username in Open Projects window listing mean?

Recently one of my co-workers account names started appearing on the right hand side of my (shared) project listing in the Open Project window and I don’t know what that means, and I cant find any documentation. Can a project somehow be attached to a different Unity account? Can anyone explain? Attaching a screenshot. I would like to know if there is some config/settings file in the Unity directory that has a user-account-specific setting in it.

Thanks!

never mind, that value is ‘organizationId’ in ProjectSettings.asset
