Two-factor authentication (2FA) adds a second security layer to your accounts. Instead of just a password, you need: 1) Something you know (your password) 2) Something you have (a code, SMS, or physical key)
4 Types of 2FA
Type 1: SMS (Least Secure)
A code sent by SMS after login. ✅ Simple ❌ Vulnerable to interception ❌ Network dependent
Type 2: App (Recommended)
Codes from Google Authenticator, Authy, or DroidPass. ✅ Safer ✅ Works offline ✅ Codes change every 30 seconds
Type 3: Physical Key (Best)
A USB security key. ✅✅ Excellent security ❌ Expensive ❌ Risk of loss
Type 4: Biometric (Practical)
Fingerprint or face recognition. ✅ Practical ✅ Safe ✅ Quick auth

Store Your 2FA Codes Securely
If your phone breaks, how do you access your 2FA codes? Solution: DroidPass
DroidPass stores your TOTP codes in the same place as your passwords, encrypted AES 256-bit, synced between devices, with autofill for codes too.
Recovery Codes
When enabling 2FA, services give you recovery codes (8-10 one-time codes). Store them in DroidPass. If you lose access, they save you.
Best Practices
- Enable 2FA on all important accounts (Email, Bank, Social Media, PayPal)
- Use App, not SMS (more secure)
- Save recovery codes in DroidPass
- Store your TOTP codes securely
- Test it before you have a problem
