Reconfigure multi-factor authentication

When you reconfigure multi-factor authentication, you can generate new codes and invalidate codes that are generated on previously-configured devices (for example, if your device was lost or stolen), or you can add other devices that will generate the same code.
If you are trying to log in and you have lost access to your device that you already configured with multi-factor authentication, click the
