The authentication is what makes it foolproof*, or at least as useful as the keyring authenticator. If you try to log in from a new IP, you have to call them from the phone number that you registered the service with and provide two numbers- a four digit PIN that you created when you signed up for the service, and a random number shown on the screen.

As someone else stated, the best part about using this service is that you can log in all of your accounts at once again. I no longer have to spend five minutes entering separate authenticator codes. Hallelujah...

* I hate to use the term foolproof, as it implies that it's impossible to get around it, and time and experience show us that people find ways around anything. But for securing your WOW account, the authentication options at least make it so that your account becomes more trouble to hack than it is worth, IMO.
