Don’t have access to the previous device?
If you no longer have access to your old device, you will need to click “Can’t Log In” on the login screen.

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 keychain. Do I need to take any action?
No. The physical authenticator is not affected by this change. However, the physical authenticator is no longer available and when the battery dies you will need to use the Battle.net Mobile App to continue using the Authenticator feature.
I have a physical Authenticator. Can I still set up an authenticator in the Battle.net Mobile App?
