How To Migrate Authenticator to Battle.net Mobile App

Anyone who uses a Battle.net account for playing games such as World of Warcraft (WoW) and Diablo 4 should take one very important step soon. Migrating their Authenticator to the Battle.net app if they haven't already.

In this guide, we explain how you can quickly and painlessly migrate your authenticator to the Battle.net app since the old Battle.net Authenticator app is being removed soon!

When Does The Old Battle.net Authenticator App Expire?

First up, take this as a PSA: You must migrate from the old, standalone Battle.net Authenticator to the new Battle.net mobile app by 5 January 2024! As early as 1 January 2024, the old Authenticator app will be removed from all app stores, including Google and Apple.

Blizzard explains what will happen to accounts that do not migrate from the old Authenticator app:

If you currently have your Battle.net Authenticator in the Battle.net Authenticator app, you must migrate to the new Battle.net mobile app by January 5. After this date, we will begin removing the authenticator from accounts which haven’t migrated, reset passwords for affected accounts, and notify all affected players of the reset.

Please note: Players who migrate their authenticator will be able to continue using the Battle.net mobile app to authenticate their account logins.

Battle.net Authenticator Migration FAQs

Check out official FAQs about the Battle.net Authenticator migration below:

Can I use the same Authenticator Serial Number to secure more than one Battle.net Account?

"The Battle.net Authenticator requires a phone number be attached to an account, and a phone number can only be attached to a single Battle.net Account."

Can I set up the same Authenticator Serial Number in more than one smartphone?

"Your unique Authenticator is tied to your mobile device and we do not support setting up the same Serial Number on more than one device."

I don't have a mobile phone number

"A mobile phone number is required to set up and use the Battle.net Authenticator. If you are unable to access your previous Authenticator contact support."

I'm not receiving the text message during setup

"Battle.net Phone Notifications are designed for text-enabled mobile phones. Messaging apps like iMessage (iOS) or WhatsApp (iOS, Android) are not supported. Phone notifications cannot be used with Voice over IP (VoIP), and VoIP numbers that are transferred to a local provider are not eligible for the service."

I have a physical Authenticator. Can I still set up an authenticator in the Battle.net Mobile App?

"Before you can attach the mobile Battle.net Authenticator you will need to remove the physical authenticator from your account."

Remember, 2FA is important to safeguard your account, so don't forget to do it as soon as possible, and definitely before 5 January 2024.
