Done, what’s next?
Congratulations, your Battle.net account is now secured!
The next time your Battle.net account tries to log in, it will request approval from your Authenticator. You will receive the approval request on your phone. You can approve or deny a log in with a simple tap.
After this, you will be asked to approve a login attempt only when you log in from a new device or location for the first time. If you want, you can choose to require an Authenticator approval for every single login attempt —this option is available in your Security options.
