SM🔐 Day 5 – Fingerprint Authentication in React Native
Today we added Biometric Login with Fingerprint Authentication to boost app security and give users a faster login experience! 🔥
✅ What’s Done:
👉 Integrated biometric auth using react-native-biometrics
👉 Fingerprint scan on app launch or login
👉 Fallback to Security PIN if biometrics fail
👉 Smooth UX with platform-native prompts (Android & iOS)
🔒 Data stored securely using device-level protection
⚙️ Toggle biometric login from Settings screen
📲 Auto-prompt for fingerprint if already authenticated once
🔁 Seamless integration with existing login/signup flow
💡 Why This Matters:
✅ Fast & secure login experience
✅ Reduces friction in user sessions
✅ Ideal for e-commerce, finance & personal apps
✅ Adds trust & professionalism to your app
📲 Built with React Native CLI + Biometrics + Custom Auth Handler
🛡️ Designed for privacy, fallback, and future expandability
