Even if someone steals your password, they cannot access your account without your 2FA code.

  2. Select Google Authenticator or 2FA binding
  3. Scan the displayed QR code
  4. Save the backup key securely
  5. Enter the 6-digit code to complete setup

3. Common 2FA Mistakes to Avoid

  • Do NOT screenshot your QR code
  • Do NOT store backup key on cloud or chat apps
  • Never share your 2FA code with anyone

4. What If You Lose Your 2FA Device?

  • Always save the backup key
