Battle.net Mobile Authenticator Now on WP7

Thursday night Blizzard said that its Battle.net Mobile Authenticator app is now available as a free download for Windows Phone 7 devices. This version follows the release of the Mobile Authenticator for Apple's iOS, Google's Android, and RIM's BlackBerry platforms over the last few years.

In addition to the smartphone apps, Blizzard customers can also purchase a standalone Battle.net Authenticator from the online Blizzard Store for $6.50. This device hangs on your keychain and will spit out a six-number security code with the press of a button.

"The Battle.net Authenticator is designed as a supplemental authentication method for your World of Warcraft account, giving you the security of Two-Factor authentication," reads the product description. "Each time you log in using the Battle.net Authenticator you are provided with a unique, one-time use password to use in addition to your regular password. Log in with both and you can rest easy knowing that your account is now even more secure from malicious attacks such as keyloggers and trojans."

Blizzard said that the Mobile Authenticator can be used on World of Warcraft and StarCraft 2 – Diablo 3 is also expected to support this feature when it launches (possibly) in Q4 2011. Currently it doesn't cover other Blizzard titles including StarCraft, StarCraft: Brood War, Diablo II, Diablo II: Lord of Destruction, WarCraft III and WarCraft III: Frozen Throne.

Once the app has been downloaded and installed, head here to set up an account. Blizzard customers can also visit the Battle.net Mobile Authenticator FAQ for more information, or for additional account security advice, check out Blizzard's Account Security page here.
