WOW Dial-In Authenticator
Blizzard announced a new tool today for security conscious people: the Battle.net Dial-In Authenticator. For those who don’t have access to a smart phone capable of running the authenticator software, or those unable to get a token authenicator, users will be able to sign up for this new service. It’s free and (currently) only available to U.S. Residents. How it works is pretty simple: you will authorize a specific phone number and make a phone call to verify it. After that every time something unusual happens with your account, such as logging in from a foreign location, you will be required to make a phone call from the registered phone number and enter your pin which will provide you with a single use security code much like the normal authenticators.
