How Many Times Can You Use Google Authenticator Backup Code?

If you have lost or stolen your security key or phone, don't worry! Google provides a backup system to ensure your account remains secure. When you use all ten backup codes, you can request and receive a new list of backup codes from Google.

To use the backup code, make sure you're using one that hasn't been used yet. If you're having trouble syncing your time, follow Google's instructions to do so manually. Ensure your device's time is correct by checking websites like 'www.time.gov'(http://www.time.gov). It's essential to note that the time may not be correctly synced between your device and authenticator app.

When requesting a backup code, you may need to try multiple codes until one works. Only the newest one-time code will be valid. Additionally, ensure you're using a phone number without an extension, as Google cannot send one-time codes to extensions. If you encounter issues, wait up to 10 minutes or try the 'Resend code' button.

When using a mobile phone, make sure airplane mode is off, and you'll receive a voicemail if you can't answer the call. For landline phones, choose to receive your one-time code by phone call instead of a text message.

It's crucial to set up additional authentication methods in case you lose access to a device that supports face or touch unlock. Try using the same device and browser you used to set it up. If you have set up face or touch unlock on another device but don't see it when signing into your account, it may mean your current device doesn't support face or touch unlock.

If you're unable to access your account due to lost devices, you can use other authentication methods such as two-factor authentication apps or verification codes sent via email. Remember that Google cannot unlock your account for you or sign in on your behalf. If you're unable to sign in with your only authentication method, you'll need to delete your account and create a new one.

In summary, if you've lost or stolen your security key or phone, you can use the backup code system provided by Google. Make sure to follow the correct procedures and set up additional authentication methods for added security.
