Last year I mentioned Blizzard’s physical token authenticator, which was an effort to crack down on theft of World of Warcraft accounts. I actually ended up ordering one of these, but never actually enabled it because it would be another device I need to keep track of and I’d probably lose it the day after I enabled it.
So it’s good to hear that Blizzard has another approach planned for the authenticator — putting an authenticator on popular mobile devices such as the iPhone,
What is the Battle.net Mobile Authenticator?
The Battle.net Mobile Authenticator is an optional tool that offers Battle.net account users an additional layer of security to help prevent unauthorized account access. This includes World of Warcraft players who log in to the game using a Battle.net account. The Authenticator application itself is a small program that you install and access on your cell phone or mobile device.
That’s a placeholder page and no app is available yet (in fact, Blizzard is still working on the transition to Battle.Net accounts for all their games), but that sounds a lot more usable than keeping track of the tiny authenticator.
