Authenticator: don't have one, can't log in

If you are being asked for an authentication code when logging into the game client or Account Management, but did not personally associate an Authenticator with your account, then it's very likely that your account has been compromised. This is unfortunately a very common trend: in many cases of compromise, an unauthorized party will associate an Authenticator with the account in order to prevent the registered user from logging in. =/

Our Account Services department can help, though! We've many representatives that are more than happy to assist you in recovering your account. Account Services representatives are available 7 days a week from 8:00 AM to 8:00 PM PDT and may be reached by phoning 1-800-59-BLIZZARD. International customers may also use the numbers listed here (http://us.blizzard.com/support/article/20606). If you're having trouble getting through, you can also email [email protected], but I would only do so in addition to your calling attempts.

I'd also encourage you to review the following step-by-step guide in full, as it will walk you through every part of the recovery process: securing your account (very important!), recovering access, reporting any losses, and what to expect from the restoration process.

Oh! One quick follow-up. Trick-of-the-trade for calling in: Spam the redial button. It may sound silly, but it's actually quite a successful technique.

The reason you're receiving that busy message is because our phone lines are completely full. This means that all representatives are on the line with other customers and all "on hold" spots are occupied. The good news is that those "on hold" spots free up all the time. If you're willing to redial for a bit, you're very likely to get through. :)

Wait times fluctuate greatly depending the number of players in queue, Snicker. Unfortunately, I am unable to provide you with an estimate at this time, but I can assure that our Billing representatives will address each call in queue just as quickly as possible.
