![]() ![]() The three most common categories, or authentication factors, are often described as something you know, or the knowledge factor something you have, or the possession factor and something you are, or the inherence factor. The use of multiple forms of authentication can help make a hacker's job more difficult. For MFA, each additional factor is intended to increase the assurance that an entity involved in some kind of communication or requesting access to a system is who - or what - it says it is. MFA authentication methodsĪn authentication factor is a category of credential used for identity verification. This is why multifactor authentication is so important, as it can help reduce security risks. Although locking an account after a certain number of incorrect login attempts can help protect an organization, hackers have numerous other methods for system access. Brute-force attacks are also a real threat, as bad actors can use automated password cracking tools to guess various combinations of usernames and passwords until they find the right sequence. ![]() One of the biggest shortcomings of traditional user ID and password logins is that passwords can be easily compromised, potentially costing organizations millions of dollars. Why is multifactor authentication important? Multifactor authentication is a core component of an identity and access management framework. Increasingly, vendors are using the label multifactor to describe any authentication scheme that requires two or more identity credentials to decrease the possibility of a cyber attack. ![]() In the past, MFA systems typically relied on two-factor authentication ( 2FA). If one factor is compromised or broken, the attacker still has at least one or more barriers to breach before successfully breaking into the target. The goal of MFA is to create a layered defense that makes it more difficult for an unauthorized person to access a target, such as a physical location, computing device, network or database. Multifactor authentication combines two or more independent credentials: what the user knows, such as a password what the user has, such as a security token and what the user is, by using biometric verification methods. Multifactor authentication (MFA) is a security technology that requires multiple methods of authentication from independent categories of credentials to verify a user's identity for a login or other transaction. ![]()
