With nothing terribly exciting going on in-game, and a lot of RL stuff happening, I canceled my WoW sub back in April. Yesterday I got an email that I assumed was another scam to try and get me to reveal my login/password. Except the message was written entirely in proper English. My curiosity was piqued, so I opened my browser and followed my bookmark to WoW's main page and tried to log-in to my account. My password still worked, but I was prompted to enter the code from an authenticator.
My question is, what all is involved in linking an authenticator to an account?
