Components of Multifactor Authentication:
- Something you know (e.g., a password)
- Something you physically have (e.g., a phone)
- Something you are (such as fingerprints or other biometric identifiers)
Answering a few questions that you keep in your head (like your favorite food, pet’s name, address, etc.) does not qualify as multifactor authentication. Many of these details can be discovered, for example, through social media.
Key Benefits of Multifactor Authentication Systems:
- High security and protection of user privacy
- Automation of the user identity lifecycle
- Two-way authentication, eliminating phishing risks
Essential Technologies for Multifactor Authentication Include: Smart cards, Tokens, Readers, Access Management, Single Sign-On (SSO), One-Time Passwords (OTP), PKI (Public Key Infrastructure)
