Review:
Mfa (multi Factor Authentication)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Multi-Factor Authentication (MFA) is a security technology that requires users to provide two or more independent credentials to verify their identity before granting access to systems, applications, or data. By combining factors such as something you know (password), something you have (security token), and something you are (biometric data), MFA significantly enhances security beyond simple password-based authentication.
