Google Authenticator failed to sync codes when I got a new phone. How can I transfer 2FA to a new device without issues?

If Google Authenticator didn't sync your codes to your new phone, you can move your 2FA accounts over by hand to make sure you can get in easily. To begin, make a QR code for sharing on your old phone. Take the old device and open Google Authenticator. Then, go to Settings > Transfer accounts > Export accounts and pick out the accounts you want to move. This turns into a QR code.

First, open Google Authenticator on your new phone. Then, go to Set up account > Import existing accounts and scan the QR code from your old phone. This moves your codes to the new phone without stopping your access.

If you can't find the old device, use backup codes or other 2FA ways to log in to each account. Then, turn off and on 2FA again, this time using the Authenticator app on your new phone.

Do you have another way to solve it? We'd love to hear from you in the comments.
