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. __TOC__ =I have my two-step authentication device= #Go to https://accounts.firefox.com and login. #Enter the authentication code from your authentication application. #After login, expand the ''Two-step authentication'' section by clicking {button Change}. #Click {button Disable}. =I lost my two-step authentication device but I have another logged-in device.= If you’re locked out of your account but have a device still logged in via two-factor authentication, you can use that device to disable two-factor authentication: #Go to https://accounts.firefox.com and login. #Click {button Disable} in the row that says ''Two-step authentication''. {note}If you don't have access to your logged-in devices and lost your two-step authentication devices, continue to the sections below.{/note} =I lost my two-step authentication device but I have a recovery code.= #Go to https://accounts.firefox.com and login. #If you are prompted for a two-step authentication code, click '''Use recovery 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'''. #Expand the Two-step authentication section by clicking {button Change}. #Click {button Disable}. =I lost my two-step authentication device, can’t find recovery codes and don’t have a logged-in device.= Unfortunately, you won't be able to deactivate two-step authentication or access your existing Sync data.
