Authentication firm SecurEnvoy has invented a simple way for remote users to log in to their organisation's network by swiping a QR code on their mobile phone in front of their laptop's webcam.
Called 'One Swipe', the user simply enters a PIN number ('something they know'), which causes the mobile app on their phone ('something they have') to generate a one-time QR code that is photographed by the webcam to complete authentication.
