Multifactor Authentication
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Multifactor authentication (MFA) is a security mechanism that requires users to provide two or more different types of verification factors before gaining access to a system, account, or service. It enhances security by combining something the user knows (e.g., password), something the user has (e.g., smartphone, security token), and/or something the user is (e.g., fingerprint, retina scan). MFA is widely adopted across industries to protect sensitive data and prevent unauthorized access.
