*Your phone must be able to receive Battle.net Phone Notifications
Setup
- If you haven’t yet, download the Battle.net Mobile App to your phone
- Open the app and when prompted, log in with your Battle.net Account
- You will be prompted to enable the Battle.net Authenticator and to set up SMS Protect if you have not yet done so
- If you need to set up SMS protect, a security code will be sent to your phone for verification
- If you did not previously have an Authenticator attached to your account, and are currently online, you will be kicked from the Battle.net desktop app, the game, and any mobile apps you are logged into
- You will be prompted to enable the Battle.net Authenticator and to set up SMS Protect if you have not yet done so
- If you are not prompted to enable the Authenticator:
- Open the slide out menu by tapping the icon at the top left of your screen
- Click on "Authenticator"
- Wait for the setup to complete
Congratulations, your Battle.net Account is now linked to your unique Authenticator Serial Number and fully protected.
Still have access to the previous device?
If you are a new Battle.net app user but previously used the Authenticator app, you can approve the login using your old authenticator application.
If you are an existing user of the Battle.net app simply tap the Authenticator option from the side menu and click Enable.
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. If you have SMS set up you can verify your identity through SMS verification to remove the old Authenticator from your account allowing you to set up the Authenticator in the Battle.net Mobile App. If you are unable to verify your account through SMS you will need to contact customer support for assistance with removing your old authenticator.
Note: The SMS verification code is sent to the phone number linked to your Battle.net Account. If you changed your phone number you will need to update your Battle.net Account phone number before you can restore your Authenticator.
What's Next?
By default, your Battle.net Authenticator will ask you to approve a login attempt only when your Battle.net Account tries to log in from a new device or location. You can approve or deny a log in with a simple tap on the notification received on your phone. If you prefer, you can choose your Authenticator to ask for approval on every login—this option is available in your Battle.net Account Security page.
If you receive an authenticator request that you did not initiate, click Deny and change your Battle.net Account's password immediately.
