WotLK Can't login to the server

[OptimiXX]

I had this account for a year and i had been neglecting it for a year. Yesterday i decided to come back and play with my friends, after i solve the issues with two step auth etc i tried to log in. But everytime i get "the information you entered is not valid" which is frustrating, afterall i am using my account name not mail address, i already changed my password, i setup two step auth altogether it is on my phone under google authanticate. Also i decided it might be a corrupted file or similar to that so i deleted woltk file altogether and redownload it from the magnet, it is fine, wow.exe works, two step auth shows up when entering my password etc, but after handshake it comes to that damned message which can't be my info is valid... so what should i do?.

make sure your password isn't to long, i believe the client limitation is something like 16 characters. website allows for longer but game won't accept it.
