Prioritize 2FA on your most critical accounts first

You do not need to enable 2FA on every account at once. Start with the five most critical: your primary email (the gateway to all password resets), bank accounts, social media, cloud storage, and your password manager itself. Add more accounts gradually.

Why It Works

Focusing on high-value targets first gives you maximum security improvement with minimum effort. Your email account is especially critical because controlling it lets an attacker reset passwords on everything else.

Tips

• Check which of your accounts support 2FA at twofactorauth.org (now 2fa.directory)
• Most major services support 2FA: Google, Apple, Microsoft, Amazon, Facebook, Instagram, X, LinkedIn
• Keep backup codes in a secure location — print them or store in your password manager
• If you lose your phone, backup codes are the only way to regain access
