We wanted to share with you and your readers that the Battle.net Mobile Authenticator is now available as a free download for Windows Phone 7 devices.
The Battle.net Mobile Authenticator provides a one-time password that you use in addition to your regular account name and password when you log in to a Battle.net account to play World of Warcraft or StarCraft II.
Versions for other mobile devices are also available for download here, or you can purchase a physical Battle.net Authenticator from the online Blizzard Store. Visit the Battle.net Mobile Authenticator FAQ for more information.
