Two-factor authentication in Firefox is implemented with help from authentication standard TOTP (Time-based One-Time Password), the post said. Apps such as Google Authenticator, Duo, and Authy all.

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.

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.

Two-step authentication in Firefox Accounts

Starting on 5/23/2018, we are beginning a phased rollout to allow Firefox Accounts users to opt into two-step authentication. If you enable this feature, then in addition to your password, an additional security code will be required to log in.

We chose to implement this feature using the well-known authentication standard TOTP (Time-based One-Time Password). TOTP codes can be generated using a variety of authenticator applications. For example, Google Authenticator, Duo and Authy all support generating TOTP codes.

Additionally, we added support for single-use recovery codes in the event you lose access to the TOTP application. It is recommend that you save your recovery codes in a safe spot since they can be used to bypass TOTP.

To enable two-step authentication, go to your Firefox Accounts preferences and click “Enable” on the “Two-step authentication” panel.

Note: If you do not see the Two-step authentication panel, you can manually enable it by following these instructions.

Using one of the authenticator applications, scan the QR code and then enter the security code it displays. Doing this will confirm your device, enable TOTP and show your recovery codes.

Note: After setup, make sure you download and save your recovery codes in a safe location! You will not be able to see them again, unless you generate new ones.

Once two-step authentication is enabled, every login will require a security code from your TOTP device.
