This requirement applies to user accounts. Multi-factor authentication requires the use of two or more different factors to achieve authentication. The authentication factors are defined as follows: something you know (e.g., a personal identification number [PIN]), something you have (e.g., a physical authenticator, such as a cryptographic private key), or something you are (e.g., a biometric). Multi-factor authentication solutions that feature physical authenticators include hardware authenticators that provide time-based or challenge-response outputs and smart cards. In addition to authenticating users at the system level, organizations may also employ authentication mechanisms at the application level to provide increased information security.the sentence this term was read in
