Overview: This article explains how to move your two-factor authentication (2FA) codes to a new phone using the Google Authenticator app. The in-app transfer works the same way on Android and iPhone.
Please refer to the Glossary for definitions of key terms used in this article.
Before you start
Before you begin, make sure:
The Google Authenticator app is installed and up to date on both phones.
You have access to your old phone.
Note: These steps apply to the Google Authenticator app. For other authenticator apps, check that app's own support.
Tip: If you are signed in to a Google Account in the Google Authenticator app, your codes may already sync automatically. Install the app on your new phone and sign in with the same Google Account, and your codes should appear without a manual transfer. If you are not signed in, use the steps below.
Transfer your accounts
The steps are the same on Android and iPhone.
On your old phone:
Open the Google Authenticator app.
Tap the menu (the three dots or your profile icon), then tap Transfer accounts.
Tap Export accounts.
Select the accounts you want to move, then tap Next. If you export more than one account, your phone may show more than one QR code.
On your new phone:
Install and open the Google Authenticator app.
Tap the menu, then tap Transfer accounts.
Tap Import accounts, then tap Scan QR code.
Scan each QR code shown on your old phone. You will get a confirmation once each transfer is complete.
Transferring does not remove the accounts from your old phone. You may be asked to confirm your identity with Face ID, fingerprint, or your phone's PIN.
If you cannot transfer your codes
If you no longer have access to your old phone, you can reset your 2FA and set it up again on your new phone. For instructions, see Resetting your 2FA / Business Fitness account Authenticator.
