Technical I can't log in my account anymore.

I'm getting the invalid account information pop up and randomly get a message that says "It's impossible to connect World of Warcraft now. Try again later."

Strange thing is that i tried with a friend account and it logs perfectly, and we both have two factor auth.

This happened today so i tried clean WTF, cache, change account password etc... still only able to log in the website and not in game.

there are only 2 cases:
1. Realmlist is wrong. Be sure you are using the correct realmlist:
set realmlist logon.warmane.com

2. Your password is too long, use a password with less than 15 characters

Same issue in here.

Reamlist is correct. My firewall is already disabled. and still cant login. Password is short too

I can log in with friend accounts, and i even created a new one to verify. Password is less than 10 characters (not going to specify how many :P).

Realmlist is not the issue, something has happened.

Try turning off two step and then log?

Deactivating the two factor auth did it for me. Thanks Justmarried!
