Does this skill support biometric authentication?

Yes, it includes implementation patterns for using expo-local-authentication to gate access to stored secure data.

Can I control when the data is accessible?

Yes, the skill covers configuration options such as WHEN_UNLOCKED or AFTER_FIRST_UNLOCK to define the security level of the stored items.

What are the storage limits for SecureStore?

SecureStore has a limit of approximately 2KB per item. It is specifically designed for small secrets like tokens and keys, rather than large datasets.

Why use SecureStore over AsyncStorage?

AsyncStorage stores data in plaintext and is vulnerable to extraction. SecureStore uses the device's secure keychain (iOS) or keystore (Android) to encrypt data at rest.

How does this handle token expiration?

The skill provides an Axios interceptor pattern that automatically detects 401 errors and attempts to refresh the session using a stored refresh token.

Mobile Development

Implements secure data storage patterns using expo-secure-store for sensitive credentials and authentication tokens in React Native applications.

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.
