Multi-Factor Authentication (MFA) is a security protocol requiring two or more independent verification methods to confirm a user's identity. Typically, the MFA process includes something the user knows (password), something the user has (their smartphone on which they can receive or generate a code), and/or something the user is (fingerprint or facial recognition). It can include passive liveness detection for added security.
Use case/ examples for Multi-Factor Authentication (MFA)
Account security: Protecting online banking and financial accounts by requiring the use of a password plus SMS verification code for access.
Corporate system access: Securing sensitive business systems through the combination of passwords and biometric verification.
Transaction authorization: Confirming high-value transactions, account recovery, or account changes by requiring multiple forms of authentication, like biometric or OTP-based authentication.
