Data Flow

Login Flow:
1. User enters email
2. Click "Continue with Passkey"
3. Call /api/webauthn/auth/options
4. Browser: navigator.credentials.get()
5. Call /api/webauthn/auth/verify
6. Create Appwrite session
7. Redirect to home

Add Passkey Flow:
1. Navigate to /settings
2. Click "+ Add Passkey"
3. Modal opens
4. Call /api/webauthn/connect/options
5. Browser: navigator.credentials.create()
6. Call /api/webauthn/connect/verify
7. Refresh passkey list

Management Flow:
1. Call GET /api/webauthn/passkeys/list
2. Display in PasskeyList component
3. User selects action (rename/delete/disable)
4. Call appropriate endpoint
5. Refresh list and show feedback

How to Use

Development

npm install
npm run dev
# Visit http://localhost:3000

Production Build

npm run build
npm start

Linting

npm run lint

Browser Support

  • Chrome/Chromium 90+
  • Firefox 78+

Environment Variables Required

NEXT_PUBLIC_APPWRITE_PROJECT=
NEXT_PUBLIC_APPWRITE_ENDPOINT=
APPWRITE_PROJECT=
APPWRITE_ENDPOINT=
APPWRITE_API=
PASSKEY_CHALLENGE_SECRET=
NEXT_PUBLIC_RP_ID=localhost
NEXT_PUBLIC_RP_NAME=Appwrite Passkey Demo
NEXT_PUBLIC_ORIGIN=http://localhost:3000

Security Considerations

✅ Private keys never leave the device ✅ Challenges are time-limited ✅ HMAC-signed tokens prevent tampering ✅ Appwrite sessions for secure state ✅ Rate limiting on all endpoints ✅ CSRF protection ✅ No sensitive data in local storage

Future Enhancement Opportunities

  • Biometric method selection UI
  • Cross-device passkey sync
  • Recovery codes
  • Audit logs
  • Device management UI
  • Multi-factor authentication
  • Email verification flow
  • Admin dashboard

Testing Recommendations

  1. Test on multiple browsers
  2. Test on multiple devices
  3. Test error scenarios (network failures, timeouts)
  4. Test rate limiting
  5. Test session expiration
  6. Test responsive design on mobile
  7. Test accessibility with screen readers
  8. Test keyboard navigation

Conclusion

The frontend implementation is complete, production-ready, and demonstrates all passkey capabilities with a modern, sophisticated user experience. All code follows Next.js and React best practices with TypeScript for type safety and ESLint for code quality.
