Remember that the codes you’re generating with Google Authenticator are key to gaining access to all of your digital accounts. If you lose access to those codes, you’re going to have to switch to a backup access method—in the case of Google accounts, that might mean entering one of the backup codes provided when you set up 2FA.
If you’re ready and determined to make the switch from Google Authenticator to Twilio Authy, you first need to make sure you’ve got both apps installed on your phone. Then you can begin switching your accounts over, one by one.
There’s no automatic or speedy process here. It’s simply a question of going into your accounts, disabling the 2FA feature temporarily, and then re-enabling it with Authy instead of Google Authenticator. You’ll only be without 2FA protection for a few seconds before you’re up and running with Authy.
Obviously, the exact process will depend on which accounts you use. With a Google account, for example, you need to open your account page on the web, select Security and 2-Step Verification, click Turn Off, confirm your choice, click 2-Step Verification again, and then click Get Started. You’ll be taken through the process of setting up 2FA on your account.
These days, Google prefers to use a prompt on your phone as the 2FA confirmation, but you’ll find an authenticator app option further down the settings screen once 2FA is back in place. Click Set Up, and you’ll eventually be shown a QR code, which you can scan using the Authy app. In Authy, tap Add Account and then Scan QR Code.
It’s always a good idea to check that the login you’ve swapped is working before moving on to the next one. To remove an account from Google Authenticator, tap and hold on it, then press the Trash Button (top right). Go through the list of accounts you’ve configured in the app, turning 2FA off and on for each one.
