Multi-Factor Authentication (MFA) refers to security mechanisms that require users to provide two or more independent credentials to verify their identity before granting access to systems, applications, or data. These credentials typically combine something the user knows (such as a password), something the user has (such as a hardware token or mobile device), and something the user is (such as a biometric identifier). Core capabilities of MFA solutions include support for a range of authentication factors, integration with existing identity and access management systems, adaptive authentication based on risk assessment, and centralized management of authentication policies. Technical scope may also encompass support for single sign-on (SSO), self-service enrollment, and compatibility with cloud, on-premises, or hybrid environments. MFA is widely adopted by organizations of all sizes and industries to mitigate the risk of unauthorized access resulting from compromised credentials. IT administrators, security teams, and compliance officers typically deploy MFA to strengthen authentication processes, meet regulatory requirements, and reduce the likelihood of account takeover attacks. Unlike single-factor authentication or basic password management tools, MFA provides layered security by requiring multiple forms of verification. It is distinct from broader identity and access management (IAM) solutions, which may include provisioning, governance, and access control beyond authentication.
