The Battle.net Authenticator is now available within the Battle.net Mobile App. The Battle.net Authenticator provides two-factor authentication to keep your Battle.net Account secure. All users must migrate their Battle.net Authenticator to the Battle.net Mobile App by January 5, 2024, as the old Authenticator App will be retired at this time.
Migrating An Authenticator
If you currently have your Battle.net Authenticator in the Battle.net Authenticator App, you should migrate to the new Battle.net Mobile App now! Once you migrate to the new app you should remove the legacy Authenticator app from your device as the codes will no longer be usable. When migration becomes required on January 5, 2024, users who have not yet migrated will have their old Authenticator removed from their account and will receive a password reset to their registered email inbox. Until the Authenticator is active in the Battle.net Mobile App, users will lose access to the perks associated with having an Authenticator on their account such as the Corehound pet, extra bag slots, and access to LFG features.

FAQ
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.
