\n\n

\n How it works:\n

• Uses your device's built-in authentication
• Biometric or PIN verification
• No passwords to remember or store
• Phishing-resistant security

\n\n

\n Troubleshooting:\n

• Make sure you're on HTTPS or localhost
• Enable biometrics/PIN on your device
• Try a different browser if issues persist
• Some corporate networks may block WebAuthn
