You’ve probably heard about the benefits of using a Battle.net Authenticator or Battle.net Mobile Authenticator app by now. But did you know that a few months ago, we introduced a new, optional security measure called Battle.net SMS Protect that works in tandem with the Authenticator to help safeguard your account?

The Battle.net Mobile Authenticator, an application for mobile phones that provides an extra layer of account security, is now available as a free download for Windows® Phone 7 devices on the Windows Phone Marketplace. 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.
