- Multi-Factor Authentication (MFA) is a security system that implements multiple authentications to verify the rationality of a transaction. The purpose of MFA is to establish a multi-layered defense that makes it more difficult for unauthorized people to access computer systems or networks.
- MFA works by combining two or three independent credentials: what the user knows (knowledge-based authentication), what the user has (security token or smart card), and what the user is (biometric authentication). In contrast, single-factor authentication (SFA) requires only the user's existing knowledge. Although password password authentication is suitable for accessing websites or applications, it is not secure enough for online financial transactions on the Internet.
- In the United States, enthusiasm for MFA has become a rule, just like the MFA directive set by the Federal Financial Institutions Review Commission (FFIEC) for online banking transactions. [1]
