How does Multi-factor Authentication (MFA) work?

Multi-factor authentication (MFA) works by requiring users to provide two or more types of identification when logging in:

1. Something You Know:
   • Traditional password.
2. Something You Have:
   • Physical or digital item like a mobile app, text message code, or hardware token.
3. Something You Are:
   • Biometric data like fingerprint, face scan, or iris pattern.

Process:

1. User enters username and password.
2. System verifies password.
3. User provides an additional form of verification (code, biometric data).
4. Access granted if all factors are verified.

MFA adds an extra layer of security, making it harder for unauthorized users to gain access even if one factor is compromised.
