🔐 1️⃣ What is Two-Factor Authentication (2FA)?
2FA is a security process that requires two forms of verification:
✅ Something You Know – Your password
✅ Something You Have – A mobile device, authentication app, or security key
Even if hackers steal your password, they can’t access your account without the second factor.
📲 2️⃣ Best 2FA Methods to Use
Not all 2FA methods are equally secure. Here’s a breakdown of the best options:
🔹 Authenticator Apps (Most Secure)
- Google Authenticator
- Authy
- Microsoft Authenticator
🔹 Hardware Security Keys (Best for High Security)
🔹 SMS and Email Verification (Less Secure, but Better than Nothing)
- Receives a code via SMS or email
- Vulnerable to SIM swapping attacks
💡 Tip: Use an authenticator app instead of SMS whenever possible for stronger security.
