By default, users won't have any second factor of authentication configured in their accounts. In the third column you can select which type of second factor will be used to verify user's identity. Once selected, in the user's next login he or she would need to pair a mobile device with the SecureAccess® CLOUD account by scanning the QR code shown in the screen. This pairing can be reset by clicking on the icon next to selected method or by disabling it and enabling it again.
