How do I disable two-factor authentication in Endpoint Central?

User/Administrator cannot access Authenticator?

The user/administrator can contact other users with administrator privileges to restore two-factor authentication using  Authenticator. Administrators can regenerate the QR code via e-mail from Admin tab -> User Administration -> Actions (Under the appropriate user) -> Regenerate QR Code. Then, proceed to open the respective authenticator app to receive the new QR code that has been generated.
