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

• If you received a message that your Firefox Account was locked because a confirmation email was returned, see the I'm having problems confirming my Firefox Account article instead.

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.

1. Go to https://accounts.firefox.com and log in.
2. Enter the authentication code from your authentication application.
3. After login, go to Security and click Disable next to Two-step authentication.
4. A confirmation prompt will appear. Click the Disable button in the Disable two-step authentication? prompt.

1. Go to https://accounts.firefox.com and log in.
2. Under Security, click Disable next to Two-step authentication.
3. Click the Disable button in the Disable two-step authentication? prompt.

1. Go to https://accounts.firefox.com and log in.
2. If you are prompted for a two-step authentication code, click Trouble entering code? and enter one of your saved recovery codes.
   • If you don't remember saving your recovery code, check if your file was downloaded and saved with the filename <your_email> Firefox Recovery Codes.txt.
3. Go to Security and click Disable next to Two-step authentication.

I lost my two-step authentication device, can’t find recovery codes and don’t have a logged-in device

Unfortunately, deactivation of two-step authentication is not supported, and you will not be able to access your existing Sync data. You can however create a new account with a different email address to begin syncing again.

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.
