SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers implement secure, reusable authentication patterns for Expo-based React Native apps, covering login flows, OAuth sign-in (Google/Apple), token management, and session handling.

Core Features & Use Cases

OAuth & Sign-in: Integrate expo-auth-session with web browser providers for Google/Apple sign-in and handle redirects reliably.
Token Management: Persist tokens securely using expo-secure-store, with safe refresh and logout flows.
Auth Context & Protected Routes: Provide a reusable AuthProvider and useAuth hook to protect routes and manage user state.
Backend Integration: Validate tokens on the backend and attach auth headers to API requests in client code.

Quick Start

Integrate rn-auth by wrapping your app with AuthProvider and using useAuth to read or update authentication state.

FAQPage Schema

How do I implement secure authentication in Expo React Native?▼

To implement secure authentication in Expo React Native, use expo-auth-session for OAuth flows and expo-secure-store for token persistence. This approach covers Google/Apple sign-in, state management, and protected navigation.

How do I manage tokens securely with expo-secure-store in React Native?▼

Manage tokens securely with expo-secure-store by persisting authentication tokens and session data locally. This enables safe token refresh and logout flows without exposing credentials in standard storage.

Does this authentication approach support Google and Apple sign-in for Expo apps?▼

Yes, this authentication approach supports Google and Apple sign-in for Expo apps. It integrates expo-auth-session with expo-web-browser to configure redirect URIs and handle backend token verification reliably.

What is the best way to protect routes in a React Native Expo application?▼

The best way to protect routes in a React Native Expo application is using an AuthProvider context and useAuth hook. This structure manages user state globally and gates navigation based on verified authentication status.

How do I validate auth tokens on the backend for an Expo React Native app?▼

Validate auth tokens on the backend for an Expo React Native app by verifying the OAuth tokens sent from the client. The client attaches auth headers to API requests, which the backend validates to authorize secure access.

Why do I need expo-auth-session and expo-web-browser for OAuth in React Native?▼

You need expo-auth-session and expo-web-browser for OAuth in React Native to handle web-based provider redirects securely. They manage the authentication flow, prompt users via the browser, and return tokens to the app.
