What is Two-Factor Authentication?

Two-Factor Authentication (2FA) is a security process that requires users to provide two different authentication factors to verify identity and access an account or service.

Something You Know

Password or PIN

Something You Have

Smartphone or hardware token

Something You Are

Biometric verification

Why 2FA Matters

Password Weaknesses

Even strong passwords can be compromised through phishing, brute force attacks, or data breaches. In 2023, credential theft accounted for 34% of all cyber attacks.

Modern Attack Vectors

  1. Phishing campaigns using deepfake audio/video
  2. Credential stuffing attacks (4.5M/day worldwide)
  3. AI-powered password guessing algorithms
  4. Zero-day exploits in popular software
