Can't log in.

I have a problem here with logging in Mists of Pandaria, after i enter my password and account name it say "Enter generated digital code" and i don't have one and don't know also where to find it. Is there any solution for this? I deleted my own two characters while i was playing Wrath of the Lich King i was about to quit the
game, maybe that could be the reason for disabling log in.

It's 2FA, you should've received a code in your email that you used to sign up with for your warmane account.
