For World of Warcraft players deadly serious about account security, Blizzard has released the Battle.net Mobile Authenticator for the iPhone. No need to carry a keychain ever again!
The free iPhone app is now available for download through the iTunes App Store, giving World of Warcraft players peace of mind with the power of a unique identifying code. No longer will someone be able to log into your WoW account to see who you're cybering with on your personal time.
It works just like the already-released keychain version, but without the need for unique hardware. All that's required is a simple download and a quick change to your Battle.net account.
If you don't have an iPhone, an iPod Touch with a working wi-fi connection will do. Expect Blizzard to offer a similar Mobile Authenticator for other mobile platforms and providers at some point in the future.
