Passkey Demo

\n Experience passwordless authentication using WebAuthn passkeys. Sign\n in securely with biometrics, PIN, or device authentication.\n

\n Passkey Authentication\n

\n Sign in securely without passwords\n

\n\n

\n {localStorage.getItem(\"passkey-credential\")\n ? (\n // Has existing passkey\n

\n You have an existing passkey. Sign in to continue.\n

\n\n \n {isLoading\n ? (\n

\n )\n : }\n {isLoading ? \"Creating Passkey...\" : \"Create Passkey\"}\n \n

\n )}\n

\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
