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.
