Secure authentication for React Native and Expo apps is achieved by integrating providers like Supabase, Firebase, or Clerk, and storing tokens using expo-secure-store. This approach handles sign-in, sign-up, and session management without exposing tokens.

The best way to store OAuth tokens securely in Expo is using expo-secure-store. It provides encrypted storage specifically designed for sensitive data, ensuring that authentication tokens and refresh flows are not exposed through insecure methods like AsyncStorage.

To protect Expo Router routes for unauthenticated users, implement an auth state management store using Zustand. This maintains session state and redirects unauthenticated users away from protected screens to the sign-in flow automatically.

Yes, this approach supports Google, Apple, and GitHub OAuth redirect flows in React Native. It handles redirect URIs correctly within Expo and WebBrowser flows, ensuring smooth OAuth authentication integration for mobile applications.

Yes, you can use Firebase or Clerk instead of Supabase for React Native session management. The implementation guides provider integration based on trade-offs like prebuilt UI and pricing, supporting email/password, magic link, and anonymous auth.

You should avoid AsyncStorage for authentication tokens in Expo because it is unencrypted and insecure. Using expo-secure-store instead ensures that tokens, credentials, and refresh flows are stored in encrypted storage, preventing unauthorized access to user sessions.
