If you have two-factor authentication (2FA) setup on your account and need to migrate to a new device or phone, here are steps you can take to ensure that you don’t get locked out of your account.

Step one: Disable two-step authentication

1. Go to https://accounts.firefox.com/settings (you may need to log in).
2. Enter the authentication code from your authentication application.
3. After login, under Security next to the Two-step authentication click Disable.
4. Click Disable on the confirmation.

Step two: Re-enable two-step authentication

Once your new device is ready to use, please follow instructions for enabling two-step authentication here. When enabling two-step authentication, all of the old recovery codes become invalid. Please ensure that you save the new recovery codes in the event your 2FA device fails.
