Multi-Factor Authentication

A security process that requires users to provide two or more verification factors to gain access to a resource.

AbbreviationMFA

Overview

MFA adds layers of security by requiring more than just a password. If one factor (like a password) is compromised, the attacker still needs the other factors to gain access.

Types of Factors

  1. Knowledge: Something you know (Password, PIN).
  2. Possession: Something you have (Smartphone, Security Key).
  3. Inherence: Something you are (Fingerprint, Face ID).

Importance

MFA is one of the most effective ways to prevent unauthorized access and account takeovers.
