Setting Up the Battle.net Mobile Authenticator

Once you have downloaded the Battle.net Mobile Authenticator software to your mobile device, you are ready to add it to a Battle.net account. The Battle.net account is Blizzard Entertainment’s centralized access for Blizzard games, websites, and online services. Please take note of the following:

  • If you have a Battle.net account, go to the Battle.net Account Management Page to add your Battle.net Mobile Authenticator. If you don’t have a Battle.net account, you can create a new account through Account Management as well. Click the “Continue to Account Management” button below to proceed.
  • If you play World of Warcraft on a US realm, and wish to use the Battle.net Mobile Authenticator to protect a World of Warcraft account, you need to take the additional step of merging the World of Warcraft account into a Battle.net account.
  • The Mobile Authenticator will automatically protect any World of Warcraft accounts that have been merged into a Battle.net account.

Frequently Asked Questions

  • Can I use a Battle.net Mobile Authenticator and a Battle.net Authenticator at the same time? You can only have one authenticator added to a Battle.net account at any given time.
  • What happens if I lose my mobile phone after activating the Battle.net Mobile Authenticator? Please contact Blizzard Customer Support if your phone is ever lost or stolen so that we can take appropriate action.
  • How do I remove the Blizzard Mobile Authenticator? You can remove the Mobile Authenticator through Battle.net Account Management. Please do not simply delete the application without first deactivating the Mobile Authenticator.
  • What happens if I delete the Mobile Authenticator application without deactivating it first? If this occurs, you will no longer be able to log in to the Battle.net account protected by the Mobile Authenticator, or any World of Warcraft accounts that have been merged into it. You must contact Blizzard Customer Support so that we can take appropriate action in this event.
  • Do I need to have an active cell phone signal or access to a wireless network in order to use the Authenticator? Why is airtime required for use? Airtime is only required in order to enable your Battle.net Mobile Authenticator for the first time, or in the rare case when you may need to resync or reset the Authenticator. Once you have enabled the Authenticator, you do not need to be in range of an active cell phone signal or have access to wireless service in order to retrieve a code to log in to World of Warcraft or other Battle.net services.
  • Will this application work with an iPod touch? Yes. However, you will need to have a valid Wi-Fi connection in order to enable the Battle.net Mobile Authenticator for the first time, or in the rare case when you need to resync or reset the Authenticator. Once the Authenticator is enabled, you do not need to have a network connection to generate a code.
