![]() ![]() A knowledge factor is something the user knows, such as a password, a personal identification number (PIN) or some other type of shared secret. ![]() Currently, most authentication methods rely on knowledge factors, such as a traditional password, while two-factor authentication methods add either a possession factor or an inherence factor.Īuthentication factors, listed in approximate order of adoption for computing, include the following: There are several ways in which someone can be authenticated using more than one authentication method. Two-factor authentication adds an additional layer of security to the authentication process by making it harder for attackers to gain access to a person's devices or online accounts because, even if the victim's password is hacked, a password alone is not enough to pass the authentication check.ĭownload this entire guide for FREE now! What are authentication factors? Two-factor authentication methods rely on a user providing a password as the first factor and a second, different factor - usually either a security token or a biometric factor, such as a fingerprint or facial scan. Two-factor authentication provides a higher level of security than authentication methods that depend on single-factor authentication ( SFA), in which the user provides only one factor - typically, a password or passcode. Two-factor authentication (2FA), sometimes referred to as two-step verification or dual-factor authentication, is a security process in which users provide two different authentication factors to verify themselves.ĢFA is implemented to better protect both a user's credentials and the resources the user can access. What is two-factor authentication and why is it used? ![]()
