WotLK Cannot enter my acc

[grotius]

Hello,
I have wired situation here. I have the two factor authentication on, and once I attempted to log in, I was asked for the code that was send on my e-mail.
I did entered the last received code, yet it says the information entered is not correct. I also changed my password just to make sure I know my password. And yes I am sure I'm entering the actual code send to my e-mail, yet I can't log in.

Halp

P.S. Removed the two factor and its all good now.
