Mis on MFA?

Multi-Factor Authentication (MFA) is a method of authentication where the user must provide two or more independent factors to verify their identity. This increases security compared to using only a password.

Main authentication factors:

• Something the user knows (password, PIN).
• Something the user has (smartphone, token, smart card).
• Something the user is (biometrics: fingerprint, facial recognition).

Example of MFA:

The user enters their password (first factor), then receives a one-time code on their phone (second factor), which they must enter.

Thus, even if the password is stolen, an attacker cannot log in without the second factor.
