Multi-Factor Authentication (MFA) is a security process that requires at least two of the three authentication factor categories to verify a user’s identity. MFA is a more general form of two-factor authentication and often involves combining different authentication requirements in various situations. This process enhances system security, particularly in the case of credential compromise, as each additional authentication factor increases the difficulty of compromising the system. For instance, while phishing for passwords can be done remotely and has a high success rate, stealing the corresponding physical token from a user’s keychain would be much more challenging.
