![]() Security tokens are small hardware devices that store a user's personal information and are used to authenticate that person's identity electronically.Possession factor technologies include the following: For mobile authentication, a smartphone often provides the possession factor in conjunction with an OTP app. Users must have something specific in their possession in order to log in, such as a badge, token, key fob or phone subscriber identity module (SIM) card. providing information, such as mother's maiden name or previous address, to gain system access.downloading a virtual private network client with a valid digital certificate and logging in to the VPN before gaining access to a network and.swiping a debit card and entering a PIN at the grocery checkout.Typical user scenarios include the following: Knowledge factor technologies generally include passwords, four-digit personal identification numbers (PINs) and one-time passwords (OTPs). Knowledge-based authentication typically requires the user to answer a personal security question. MFA works by combining two or more factors from these categories. 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. Different methods of user authenticationÄownload this entire guide for FREE now! MFA authentication methodsĪn authentication factor is a category of credential used for identity verification. 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.
