The 3 3 Types of Authentication & MFA Basics 🔐

About this video

STOP relying on just a password! 🛑 In this episode of Cyber Samurai, we break down the single most effective way to secure your digital life: Multi-Factor Authentication (MFA).
If you watched our last video on the CIA Triad, you know that "Confidentiality" is key. MFA is the tool that guarantees it. Today, we explain the difference between a weak defense and a fortress by exploring the three core factors of authentication:

1️⃣ Something You Know: (Passwords, PINs)

2️⃣ Something You Have: (Smartphones, USB Keys)

3️⃣ Something You Are: (Biometrics, FaceID, Fingerprints)
Don't let hackers guess your password and walk right in. Learn how to layer your defenses like a pro.
👇 In this video:
• What is Multi-Factor Authentication?
• The 3 Categories of Credentials.
• Why "Two-Factor" (2FA) is safer than a password alone.
