Ensures that a user is who he or she claims to be. The more factors used to determine a person's identity, the greater the trust of authenticity.
Multi-Factor Authentication Definition: Ensures that a user is who he or she claims to be. The more factors used to determine a person's identity, the greater the trust of authenticity.
Ensures that a user is who he or she claims to be. The more factors used to determine a person's identity, the greater the trust of authenticity. Multi-factor authentication requires users to provide two or more verification factors from different categories: something you know (password, PIN), something you have (token, card, mobile device), and something you are (biometrics). This significantly increases security by requiring attackers to compromise multiple authentication mechanisms. MFA is required by numerous standards, including NIST SP 800-63, PCI DSS, HIPAA, and ISO 27001. Organizations implement MFA through various technologies, including authenticator apps, hardware tokens, biometric systems, SMS codes, and smart cards. For example, a financial institution might require customers to enter both a password and a one-time code generated by a mobile authenticator app when logging into online banking, especially for high-risk transactions like wire transfers or changing account information. Related terms: Two-factor authentication, Authentication factors, Single sign-on, One-time password, Hardware token, Biometric authentication, Identity and access management.
Multi-Factor Authentication is one of the topics you'll master in the Security+ Boot Camp.
