If you’re not using Google Authenticator or some sort of two-factor authentication app, you should be. If you’ve opted for Google Authenticator, but have switched to a new phone, switching your phone is not an entirely straightforward task. Here’s what you need to do.
How to Switch Google Authenticator to a New Phone
You’re going to want to do this while the old phone is still in your possession with the Google Authenticator app still installed.
- Install the iOS or Android Google Authenticator app on your new phone.
- Load the Google Authenticator page in a browser. You’ll be prompted to log in with your Google credentials.
- You should see the Authenticator app listed. Click Change phone.
- In the popup window, you’ll be prompted select what kind of new phone you have: Android or iPhone. After you make your selection click Next.
- Open up the Google Authenticator app on your new phone and tap Begin setup > Scan barcode.
- Once you’ve used your new phone to scan the barcode displayed in your browser, click Next in your browser. You’ll be prompted to enter the authenticator code you see on your phone.
- Click Verify.
- If you’re using the Google Authenticator for other apps, you’ll need to login to each of those sites separately to remove the old Google Authenticator app and add your new phone, also by scanning the QR code.
- You can now go onto your old phone, click the Edit button (pencil icon) and delete the individual authenticator codes, and delete the app.
