I came back from a break of gaming of a year, and wanted to play some WoW, but i have problems with the to fact authentification system, cuz i ve changed my phone since the last time i was playing ( a year ago) and now i cant log in in the Authetificator app since the QR code aint valid anymore or i cant sign in on Warmane also, since i need the two fact auth. What can i do to take my account back? i have all i need but not the code for app so i can log in into it. Any suggestions?
Go here and select "Two factor auth removal".
If you can't remove it that way send an e-mail to [email protected] with all the proof you have that you own the account and they will remove it for you but that might take a while.
