Were you looking for Blizzard Authenticator (key fob device)?

The Mobile Authenticator is a small mobile phone application that functions similarly to the Blizzard Authenticator key fob device. However, it cannot be used in conjunction with the other device, one or the other can be used, but not both.[1]

The application is available for the iPhone (with iPhone OS 3.0[2]) and many other mobile smartphones. The iPhone app is a free download. As with many iPhone apps, it can be used with the iPod Touch, but requires a wi-fi connection during setup (or re-setup or re-sync to restore the app).[2]

Desktop port

A fansite has ported a version of the Mobile Authenticator to a PC application. It is not as secure, but they are currently requesting feedback on a trial version. Contact Nihilum for a copy. [3]


  • This application was announced on March 31st, 2009 on the US official forums and June 2nd, 2009 on the EU official forums.[4][5]
  • The Mobile Authenticator app was not available in mid to late September 2009 for some reason. Several blue posts stated this fact, but no reason was given.
