Understanding Two-Factor Authentication

Two-factor authentication (2FA) is one of the most effective ways to protect your Ledger Live account. In this tutorial, we'll explain what 2FA is and how to set it up properly.

What is 2FA?

Two-factor authentication requires two forms of verification before granting access to your account. The first factor is typically your password, and the second is usually a code from your phone.

Types of 2FA

There are several types of 2FA available:

• <strong>Authenticator Apps</strong>: Apps like Google Authenticator or Authy generate time-based codes
• <strong>SMS</strong>: Codes sent via text message (less secure)
• <strong>Biometric</strong>: Fingerprint or face recognition
• <strong>Hardware Keys</strong>: Physical security keys like YubiKey

Setting Up 2FA on Ledger Live

Follow these steps to enable 2FA:

1. Download an authenticator app on your phone 2. Go to Security Settings in Ledger Live 3. Select "Enable Two-Factor Authentication" 4. Scan the QR code with your authenticator app 5. Enter the 6-digit code to confirm

Backup Codes

When you enable 2FA, you'll receive backup codes. Store these securely in case you lose access to your authenticator app.

Best Practices

• Never screenshot your QR codes
• Use biometric locks on your authenticator app
• Keep backup codes in a safe place
• Avoid SMS-based 2FA when possible

Conclusion

Setting up 2FA only takes a few minutes but provides substantial protection for your crypto assets. Don't wait - enable it today!
