概要
This skill provides a standardized approach to handling sensitive information in Expo and React Native projects by leveraging expo-secure-store instead of insecure alternatives like AsyncStorage. It offers ready-to-use implementation patterns for token management, refresh token logic, user data encryption, and biometric authentication integration. By following these 'secure by default' practices, developers can ensure that authentication secrets and private user data are protected within the device's hardware-backed keychain or keystore, significantly improving the security posture of mobile applications.
