Step 1: Choosing the Right 2FA Method
Available Options:
| Method | Pros | Cons |
|---|---|---|
| Authenticator Apps (Google Authenticator, Authy) | High security; offline codes | Requires device access |
| SMS Verification | Easy setup | Vulnerable to SIM swapping |
| Hardware Tokens (YubiKey) | Phishing-resistant | Physical device required |
| Biometric Verification | Convenient | Limited device compatibility |
Recommendation: Authenticator apps offer the best balance of security and convenience.
Step 2: Setting Up 2FA for Your Wallet

- Store backup codes securely (e.g., encrypted password manager).
Step 3: Best Practices for Securing Your 2FA
- Use separate devices for passwords and 2FA codes
- Regularly update authentication methods
- Enable biometric locks on authenticator apps
- Monitor login attempts with activity alerts
