How To Recover Google Authenticator Codes

Google Authenticator codes help protect online accounts by adding an extra layer of security through two-factor authentication (2FA). However, losing access to the app, changing phones or accidentally deleting it can make it difficult to sign in to accounts that rely on these verification codes.

Fortunately, there are ways to recover access to Google Authenticator codes, depending on how the app was configured and whether the previous phone or its data is still available.

Google Authenticator supports cloud synchronisation through a Google Account and manual account transfers between devices. If synchronisation was enabled before losing the phone, saved authenticator accounts can be restored by signing in with the same Google Account on the new device.

Here are the different ways to recover Google Authenticator codes and regain access to accounts protected by two-factor authentication.

1. Restore Google Authenticator Codes Using a Google Account

If Google Authenticator synchronisation was enabled, recovering saved codes is straightforward. The app can restore synchronised authenticator accounts when signed in with the same Google Account.

Follow these steps:

1. Install Google Authenticator from the Google Play Store or Apple App Store on the new phone.
2. Open the app.
3. Select the option to sign in with a Google Account if prompted.
4. Sign in using the same Google Account previously used for synchronisation.
5. Allow the app to synchronise the saved authenticator accounts.

Once synchronisation is complete, the available accounts should appear in Google Authenticator with their verification codes.

Important: This method only works for accounts that were synchronised before access to the previous device was lost. Simply signing into a Google Account will not restore codes that were stored only on the old phone.

2. Transfer Google Authenticator Codes From an Old Phone

If the previous phone is still available and Google Authenticator is working, you can transfer your authenticator accounts directly to another device.

This method is useful when changing phones or setting up a replacement device.

Follow these steps:

1. Open Google Authenticator on the old phone.
2. Tap the menu icon or profile icon, depending on the app version.
3. Select Transfer accounts.
4. Choose Export accounts.
5. Select the accounts you want to transfer and continue.
6. Complete any required screen-lock or identity verification.
7. A QR code will appear on the old phone.
8. Open Google Authenticator on the new phone.
9. Select Transfer accounts and choose Import accounts.
10. Scan the QR code displayed on the old phone.

The selected authenticator accounts will be added to the new device.

Keep both phones available until the transfer is complete and confirm that the verification codes work before removing the app from the old phone.

3. Recover Access Using Backup Codes

Some websites and online services provide backup codes when setting up two-factor authentication. These codes can be used to sign in when Google Authenticator is unavailable.

If you saved backup codes when enabling two-factor authentication, follow these steps:

1. Visit the login page of the account you want to access.
2. Enter your username and password.
3. When prompted for a verification code, select an alternative verification option.
4. Choose the backup code option if available.
5. Enter one of the unused backup codes.
6. Follow the remaining instructions to complete the sign-in process.

Backup codes are usually provided by individual websites and services rather than Google Authenticator itself. Each code may only be used once.

After regaining access, generate a new set of backup codes if the service provides that option.

4. Use an Alternative Verification Method

If you cannot access Google Authenticator and do not have backup codes, check whether the affected account offers another way to verify your identity.

Depending on the service, available alternatives may include:

• SMS verification sent to a registered phone number.
• Email verification sent to a recovery email address.
• A security key or passkey.
• Another trusted device that is already signed in.
• An account recovery process.

Open the affected service's sign-in page, enter your login details and look for options such as Try another way, Use another method or Can't access your authenticator?

Select an available option and follow the instructions to verify your identity.

The available methods depend on the security settings of the individual account.

5. Contact the Account Provider for Recovery Assistance

If the previous methods are unavailable, contact the support team of the website or service you are trying to access.

Google Authenticator generates verification codes for different online accounts, but it does not control the login and recovery systems of those services.

For example, if you cannot access a Facebook, Instagram, Microsoft or cryptocurrency account because you lost your authenticator codes, you need to follow that service's official account recovery procedure.

Be prepared to provide the information requested to verify account ownership. Never share your password, verification codes or backup codes with anyone claiming to offer recovery assistance.

How to Prevent Losing Google Authenticator Codes Again

After recovering access, take steps to protect your authenticator accounts against future device loss.

• Enable Google Account synchronisation: Sign in to Google Authenticator with a Google Account and ensure synchronisation is active.
• Save backup codes: Keep recovery codes provided by individual websites in a secure location.
• Keep an old device temporarily: When changing phones, confirm that all authenticator accounts work on the new device before resetting the old one.
• Update recovery information: Ensure that important accounts have accessible recovery email addresses and phone numbers.
• Protect your Google Account: Use a strong password and additional security measures to prevent unauthorised access.

Frequently Asked Questions (FAQs)

1. Can I recover Google Authenticator codes without my old phone?

Yes. You can restore synchronised codes by signing in with the same Google Account on a new device. Otherwise, you may need backup codes or account recovery options.

2. Can I recover Google Authenticator codes after deleting the app?

Yes, if the codes were synchronised with your Google Account. If they were stored locally, recovery may require the old device or the affected account's recovery process.

3. Can Google Authenticator codes be used more than once?

No. Each verification code expires after a short period, usually 30 seconds. You must enter a valid current code to complete verification.

4. Does removing an account from Google Authenticator delete the actual online account?

No. Removing an account entry from Google Authenticator only deletes its verification code from the app. It does not delete the associated online account.
