After I've setup my installation of Q2A I've got myself an admin user named 'atrandafir'. Then, I have installed Facebook Login Plugin and I've gave it a try. So now I've got another user for myself that logs in using Facebook.
I just want to use one user, not both, but the first one does not have Facebook Login, and the second one has it but it is not an admin.
Is there a way I can unlink Facebook Login from one user and link it to another?
