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.
