My account asks me for Authenticator key?

Q u o t e:
Hello, So today i decided to play wow and when i tryed to log in, my account asked me to enter an Authenticator key. i never used one for bought one, and i am confused. Any help?

You've been compromised, Rythore - and they were still actively in the account.

I asked this be locked for your protection. You should be receiving further instructions and a new password soon.

What is vital at this time is finding out how they acquired your password and ID. If that source is not identified, the chances of this happening again are VERY high.

You may also want to look into getting an authenticator for your account. It's no substitute for good security habits, but it will help keep them out of your WoW account.
