What is 2FA?
Two-Factor Authentication (2FA) adds an extra layer of security by requiring two forms of verification before allowing login. Even if someone guesses your password, they'd need your second factor to access your account.
- Password + device
- One-time codes or apps
- Blocks unauthorized access
Enable 2FA on Your Accounts
Step 1: Access Security Settings
Go to your account settings and locate the "Security" or "2FA" section. Common platforms include Google, Microsoft, and Facebook.
Step 2: Choose 2FA Method
Select a preferred method: Authenticator apps, SMS codes, backup codes, or hardware security keys.
Step 3: Setup & Backup
Complete the setup process and save backup codes or recovery options in a secure password manager.
Supported 2FA Methods
Authenticator Apps
Use apps like Google or Microsoft Authenticator for secure codes.
SMS/Phone Call
Receive one-time codes via text message or voice call (less secure).
Backup Codes
Generate and store physical or digital recovery codes for emergency access.
Hardware Keys
Use physical security keys from providers like YubiKey for maximum security.

Avoid SMS for 2FA
SMS is vulnerable to SIM swapping attacks. Prefer app-based codes or security keys.
Regularly Test 2FA
Verify your 2FA setup works with test signs-in to avoid lockouts.
In Summary
Two-Factor Authentication is a critical security layer that protects against password guessing and account takeovers. Always enable it on all major accounts including email, banking, and social media.
