For React Native, the best choice for OAuth is usually:
Recommended: Authorization Code Flow with PKCE
This is the modern, secure approach for mobile apps.
Use a library that supports opening the system browser and handling redirects, such as:
react-native-app-auth— a popular choice for OAuth/OIDC- Expo:
expo-auth-sessionif you're using Expo react-native-inappbrowser-reborn— useful if you need more control over the browser experience
Why this is the right approach
- Avoids using embedded webviews for login
- Uses the device’s secure browser context
- PKCE protects against code interception
- Works with most OAuth providers and OpenID Connect providers
Avoid
- WebView-based OAuth for production login flows
- Many providers discourage or block it
- It’s less secure than system-browser auth
If you want a quick pick
- Bare React Native app:
react-native-app-auth - Expo app:
expo-auth-session
If you tell me whether you’re using Expo or bare React Native, and which provider you’re targeting (Google, GitHub, Auth0, Azure AD, etc.), I can recommend the exact setup.
