Authenticating Issue

Q u o t e:
When i try and log in it says i need to type in a six digit number authenticating password but i never bought one and iam afraid someone has hacked me. Please tell me what to do or help me as soon as possible

Well, they were still in the account, so I asked this be locked for you.

You should be receiving an email with instructions on how to get it unlocked once you are certain your system and email are secure.

That is the priority at the moment. You need to determine how they obtained your password and ID because if they CAN still get in, they WILL be back.

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.
