React Native Google Login

Social media Authentication like Google login is becoming necessary while building the authentication flow of a mobile app. In React Native, this can easily be achieved in a few minutes.


  • expo-google-app-auth

Go ahead and install expo-google-app-auth dependency with:

expo install expo-google-app-auth

The only method you need

import * as Google from "expo-google-app-auth";

const config = {
 androidClientId: YOUR_CLIENT_ID_HERE,
 scopes: ['profile', 'email'],

const logInWithGoogle = async () => {
 try {
   const { type, accessToken, user } = await Google.logInAsync(config);
   if (type === "success") {
     /* `accessToken` is now valid and can be used to get data from the Google API with HTTP requests like below */
     let response = await fetch(
       headers: { Authorization: `Bearer ${accessToken}` },
     response && console.log(response);
   } else {
    // type === 'cancel'
 } catch ({ message }) {
    alert(`Google Login Error: ${message}`);

(If you need an already implemented solution, get free and premium templates with the complete backend at QuickComponent).

To log the user out use method:

Google.logOutAsync({ accessToken }) - pass the accessToken previously gotten during login to invalidate it.

follow the detailed instructions here to see how to get values of Google Login config such as; iosClientId and androidClientId.
