If you have two-factor authentication (2FA) set up on your Firefox 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
- Go to https://accounts.firefox.com/settings (you may need to log in).
- Enter the authentication code from your authentication application.
- After login, under Security next to Two-step authentication, click .
- Click on the confirmation.
Step two: Re-enable two-step authentication
Once your new device is ready to use, enable two-step authentication by following the instructions in Secure your Firefox Account with two-step authentication.
Warning: 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.
