Changing your two-step authentication device for your Firefox Account

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

  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 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, 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.
