This article explains what to do if you have been locked out of your Firefox Account two-step authentication login.

Two-step authentication adds extra security to your Firefox account by making it harder for someone else to log in to your account. If you’ve gotten locked out of your two-step authentication login, you can use a recovery code to securely regain access to your account. Alternatively, if you have a device still signed in to your account, you can use that device to disable two-factor authentication so you can log in to your account without two-factor authentication.

Please help us prevent these problems in the future by filling out this short survey.

I lost my two-step authentication device, can’t find recovery codes and don’t have a logged-in device. Can I request to delete my Firefox Account?

In this case it is currently not possible to delete your Firefox Account since we don't have a way to verify your identity and ownership of that account. We recommend creating a new Firefox Account to use Firefox Sync and other services that require a Firefox Account.
