How to transfer your Google Authenticator 2FA to a new phone

Transferring Google Authenticator to a new phone can be easy — if you’ve prepared ahead of

Curated via Twitter from The Verge’s twitter account….

Just throw the screenshot up on your computer, install Google Authenticator on your new phone, and use the plus sign on the app to scan the barcode. (You can also enter the setup key code if that’s what you saved. ) Do this for each of your apps, and you’ll be all set.

In this article, I’m going to look at Google Authenticator, including the easiest way to transfer the app to a new phone if you do have access to the old one, and how you can prepare for a possible problem (like a broken phone).

Google Authenticator lets you establish 2FA by using your phone to scan a QR code generated by the app on a separate device or by entering a key code.

If you’ve mislaid your backup codes, but you’ve saved a screenshot of the QR barcode that you originally used to create your app’s authentication, you can use that screenshot to establish your credentials on a new phone.

If you’ve got two Android phones, you can transfer your accounts to a new phone by exporting them via a QR code generated by the Authenticator app.

The easiest method, especially if you use 2FA with several apps, is to use the Authenticator app’s dedicated transfer feature to move your keys from one phone to the other.

Because 2FA uses security keys that are specific to each piece of hardware, you can’t simply reinstall Google Authenticator on your new phone and use it to log in.

They work by issuing an authentication code on your phone when somebody tries to access the account; if that person doesn’t have the code, they (or you) don’t get in.

When you set up an app to use Google Authenticator, before the process is completed, you are given a set of four backup codes and asked to print them out or otherwise save them. (In fact, Google will ask you to enter one of the codes into a field before it will finish the installation, just to make sure you have saved them.
