Secure Student-Only Auth (ID Card Scan + OTP)
✅ Auth Flow
-
ID Card Scan
- OCR extract student ID info
- Match with backend student records
-
OTP Verification
- Send OTP to registered phone/email
- Verify OTP to authenticate
-
Secure Session
- Issue JWT or session token
- Store token securely on device
Recommended Libraries (React Native)
| Task | Library |
|---|---|
| OCR / ID Scan | react-native-ml-kit |
| OTP Auth | @react-native-firebase/auth |
| Secure Token Store | react-native-keychain / SecureStore |
| HTTP Requests | axios (with HTTPS) |
Security Tips
- Use on-device OCR to avoid PII leaks
- OTP: 5 min expiry, rate limit, secure backend check
- Store tokens in Keychain, not AsyncStorage
- Always use HTTPS
- Validate student ID → OTP on server-side
