Can I use this for both React Native CLI and Expo?

While the templates leverage Expo-specific libraries like expo-secure-store, the core logic and session management patterns are applicable to all React Native projects.

Which auth providers does this skill support?

It provides optimized templates and patterns for Clerk, Supabase, Apple Sign-In, and Google Sign-In.

How does it store sensitive tokens?

It uses expo-secure-store to ensure authentication tokens are saved in hardware-backed encrypted storage rather than insecure AsyncStorage.

Does it handle biometric authentication?

Yes, it includes logic for FaceID, fingerprint, and iris recognition using expo-local-authentication, including fallback passcode handling.
