Auth0 React Native Integration Add authentication to React Native and Expo mobile applications using react-native-auth0. Prerequisites React Native or Expo application Auth0 account and application configured as Native type If you don't have Auth0 set up yet, use the auth0-quickstart skill first When NOT to Use React web applications - Use auth0-react skill for SPAs (Vite/CRA) React Server Components - Use auth0-nextjs for Next.js applications Non-React native apps - Use platform-specific SDKs (Swift for iOS, Kotlin for Android) Backend APIs - Use JWT validation libraries for your server language Quick Start Workflow 1. Install SDK Expo: npx expo install react-native-auth0 React Native CLI: npm install react-native-auth0 npx pod-install

iOS only

1. Configure Environment For automated setup with Auth0 CLI , see Setup Guide for complete scripts. For manual setup: Create .env : AUTH0_DOMAIN = your-tenant.auth0.com AUTH0_CLIENT_ID = your-client-id
2. Configure Native Platforms iOS
3. Update ios/{YourApp}/Info.plist : < key

   CFBundleURLTypes </ key

   < array

   < dict

   < key

   CFBundleTypeRole </ key

   < string

   None </ string

   < key

   CFBundleURLName </ key

   < string

   auth0 </ string

   < key

   CFBundleURLSchemes </ key

   < array

   < string

   $(PRODUCT_BUNDLE_IDENTIFIER).auth0 </ string

   </ array

   </ dict

   </ array

   Android

4. Update android/app/src/main/AndroidManifest.xml : < activity android: name = " com.auth0.android.provider.RedirectActivity " android: exported = " true "

   < intent-filter

   < action android: name = " android.intent.action.VIEW " /> < category android: name = " android.intent.category.DEFAULT " /> < category android: name = " android.intent.category.BROWSABLE " /> < data android: host = " YOUR_AUTH0_DOMAIN " android: pathPrefix = " /android/${applicationId}/callback " android: scheme = " ${applicationId} " /> </ intent-filter

   </ activity

   Expo

5. Update app.json : { "expo" : { "scheme" : "your-app-scheme" , "ios" : { "bundleIdentifier" : "com.yourcompany.yourapp" } , "android" : { "package" : "com.yourcompany.yourapp" } } }
6. Add Authentication with Auth0Provider Wrap your app with Auth0Provider : import React from 'react' ; import { Auth0Provider } from 'react-native-auth0' ; import App from './App' ; export default function Root ( ) { return ( < Auth0Provider domain = { process . env . AUTH0_DOMAIN } clientId = { process . env . AUTH0_CLIENT_ID }

   < App /

   < / Auth0Provider

   ) ; }

7. Use the useAuth0 Hook import React from 'react' ; import { View , Button , Text , ActivityIndicator } from 'react-native' ; import { useAuth0 } from 'react-native-auth0' ; export default function App ( ) { const { user , authorize , clearSession , isLoading } = useAuth0 ( ) ; const login = async ( ) => { try { await authorize ( { scope : 'openid profile email' } ) ; } catch ( error ) { console . error ( 'Login error:' , error ) ; } } ; const logout = async ( ) => { try { await clearSession ( ) ; } catch ( error ) { console . error ( 'Logout error:' , error ) ; } } ; if ( isLoading ) { return < ActivityIndicator /

   ; } return ( < View

   { user ? ( <

   < Text

   Welcome , { user . name } ! < / Text

   < Text

   { user . email } < / Text

   < Button title = "Logout" onPress = { logout } /

   < /

   ) : ( < Button title = "Login" onPress = { login } /

   ) } < / View

   ) ; }

8. Test Authentication Expo: npx expo start React Native: npx react-native run-ios

or

npx react-native run-android Detailed Documentation Setup Guide - Automated setup, native configuration, deep linking Patterns Guide - Secure storage, biometric auth, token refresh API Reference - Complete SDK API, methods, configuration options Common Mistakes Mistake Fix Forgot to wrap app with Auth0Provider All components using useAuth0() must be children of Auth0Provider Forgot to configure deep linking Add URL scheme to iOS Info.plist and Android AndroidManifest.xml (see Step 3) Callback URL mismatch Ensure callback URL in Auth0 Dashboard matches your app's URL scheme (e.g., com.yourapp.auth0://YOUR_DOMAIN/ios/com.yourapp/callback ) iOS build fails after install Run npx pod-install to link native dependencies App created as SPA type in Auth0 Must be Native application type for mobile apps Not handling auth errors Wrap authorize/clearSession calls in try-catch blocks Deep link not working on Android Verify android:exported="true" is set on RedirectActivity
