# OAuth2 Login

Use #oauth2 login with React-Native

## Common OAuth2 providers

Can be handled by react-native-app-auth by redirecting to url `com.yourapp://oauth2provider`.

### Example for #Google

    import { authorize } from 'react-native-app-auth';const GOOGLE_OAUTH_CLIENT = '...';// ...const authState = await authorize({  issuer: 'https://accounts.google.com',  clientId: `${GOOGLE_OAUTH_CLIENT}.apps.googleusercontent.com`,  redirectUrl: `com.yourapp:/oauth2redirect/google`,  scopes: ['openid', 'profile'],  dangerouslyAllowInsecureHttpRequests: true,});

### Example for #Yandex

    const YANDEX_OAUTH_CLIENT = '...';const YANDEX_OAUTH_SECRET = '...'; // better hide it somehowconst APP_ID = 'com.yourapp';const authState = await authorize({  serviceConfiguration: {    authorizationEndpoint: `https://oauth.yandex.ru/authorize?response_type=code&client_id=${YANDEX_OAUTH_CLIENT}&redirect_uri=${APP_ID}:/oauth2redirect`,    // TODO: replace it with your own backend to secure client_secret:    tokenEndpoint: `https://oauth.yandex.ru/token?grant_type=authorization_code&client_id=${YANDEX_OAUTH_CLIENT}&client_secret=${YANDEX_OAUTH_SECRET}`,  },  clientId: YANDEX_OAUTH_CLIENT,  redirectUrl: `${APP_ID}:/oauth2redirect`,  scopes: ['login:info', 'login:avatar'],  dangerouslyAllowInsecureHttpRequests: true,});callback(authState.accessToken);

## Apple ID login

react-native-apple-authentication has its own documentation on setting up OAuth using Apple ID.
