Two Factor Authentication is a security process in which the user is required to verify their identity through two separate steps. Instead of just a password Two Factor Authentication (2FA) asks the user to go through an additional step, such as; a location factor, knowledge factor, possession factor, inherence factor, or time factor. This second step makes it much more difficult for security threats to occur. A password alone (also known as a knowledge factor) can be hacked more easily than a fingerprint or face scan (inherence factors), and the combination of having both a password and a second factor helps to eliminate potential attacks, as the probability an attacker could obtain two separate factors is unlikely.
