Quizplus · Accepted Answer

This process is known as dual authentication, also commonly referred to as two-factor authentication (2FA). It adds an extra layer of security by requiring not only a password and username but also something that only the user has on them, i.e., a piece of information only they should know or have immediately to hand - such as a physical token, a temporary code sent to a mobile device, etc.
