An authenticator generates a one-time password, which you use in addition to an account ID and password to log in to World of Warcraft and other Blizzard Entertainment services. The Battle.net Mobile Authenticator performs this function for the recently launched Battle.net accounts -- only instead of a physical token, the application exists on your mobile phone for easy access.
The Battle.net Mobile Authenticator is now available as a free download for the Apple iPhone and iPod touch from the Apple App Store. Versions for other mobile phones are also in the works for the future. Please visit the Battle.net Mobile Authenticator FAQ for more information, or head to the setup page to get started after you’ve downloaded the application.Our complete transcript includes exclusive new screenshots of Diablo III and StarCraft II, as well as a short example movie from Diablo III.
