Google Authenticator works by generating a time-based one-time password (TOTP) using a secret key and the current time. When a user sets up two-factor authentication with Google Authenticator, a unique secret key is generated and stored on the user's device. When the user tries to log in to their account, they must enter the TOTP generated by the Google Authenticator app in addition to their regular password. The TOTP is only valid for a short period of time, typically 30 seconds, adding an extra layer of security to the login process. **

The Battle.net Authenticator is recoverable in case it is lost or damaged. Users can remove the Authenticator from their account by providing a government-issued ID and a selfie to verify their identity. Once the Authenticator is removed, users can set up a new one to secure their account. **

To switch the Google Authenticator to a new device, you will need to first install the Google Authenticator app on the new device. Then, you will need to log in to each of your accounts that use Google Authenticator and disable two-factor authentication. After disabling it, you can re-enable two-factor authentication and scan the QR code with the new Google Authenticator app on your new device. This will transfer the two-factor authentication codes to your new device. Make sure to securely store backup codes in case you lose access to your Google Authenticator app. **

To restore Google Authenticator, you will need to have access to the backup codes that were provided when you initially set up the app. If you do not have the backup codes, you will need to contact the service or website that you were using the Authenticator with and follow their specific account recovery process. Once you have the backup codes or have completed the account recovery process, you can re-enable Google Authenticator by setting it up again with the same accounts or services. Remember to securely store your backup codes in a safe place to avoid future issues with restoring Google Authenticator. **

Yes, Google Authenticator still sends confirmation codes. When a user logs into a website or app that has two-factor authentication enabled, they will receive a confirmation code from Google Authenticator to verify their identity. This adds an extra layer of security to the login process by requiring something the user knows (their password) and something they have (their phone with the Google Authenticator app). **

If you have lost access to your Google Authenticator code, you can typically retrieve it by using the backup codes that were provided to you when you first set up two-factor authentication. These backup codes are meant to be used in situations where you cannot access your Google Authenticator app. If you do not have your backup codes, you may need to go through the account recovery process with the service that uses Google Authenticator for authentication. This process may involve verifying your identity through other means, such as email or phone verification. **
