Angular 14 Login with Google using OAuth 2.0


In this article, I will explain how to implement login with google or sign in with a google account in angular 14 using Angular 14 introduced a new way to handle login with Google. Previously, developers would have to use the Google Plus API to login with Google. Now, developers can use the Google Sign-In SDK. The Google Sign-In SDK is a more secure way to login with Google. It uses the OAuth 2.0 protocol to authenticate users.

I got many requests from beginner IT professionals as well as students via email to write an article about the implementation of login with a Google account using the OAuth 2.0 protocol, So in this article, I’ll explain how to implement sign-in with google using OAuth 2.0 protocol in angular application step by step.

In my previous article I explained:


2. Create a new angular application.

Implement login with google using google OAuth 2.0 protocol.


So, let’s start with an example for demonstration.

Step1: Create Google App

Let’s create a google app and generate the client id and secret key, so let’s go to Google Console.

You can also follow the steps for Setting up OAuth 2.0 which is provided by the google cloud platform console team.

Now, just follow the steps to create a new project in the google console cloud platform.

Create New Project in Google Console

Create New Project

OAuth Consent Screen

OAuth Consent Screen - App Information

Create OAuth Client Id

Application Type - Web Application

Create OAuth Credentials

Authorized JavaScript Origins

Create OAuth Client ID and Secret

Step 2: Create a new angular application

To create a new angular application, open the PowerShell window and write the following command.

ng new Codingvila_Login_With_Google

If you create a new angular application the first time and get any error, you have to install angular CLI and other related packages as well as you need to install the LTS version of Node.js. You can read my article Angular 14 CRUD Example with Web API where I explained each and every step with an example.

Step 3: Update the app / app.component.ts file.

import  OnInit  from '@angular/core';
import  ViewChild  from '@angular/core';
import  Component  from '@angular/core';
import  ElementRef  from '@angular/core';

  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent implements OnInit{
  title = 'Codingvila Login With Google';
  auth2: any;
  @ViewChild('loginRef',  static: true ) loginElement!: ElementRef;



    this.auth2.attachClickHandler(this.loginElement.nativeElement, ,
      (googleAuthUserany) =>  ' + googleAuthUser.getAuthResponse().id_token);
        console.log('ID: ' + profile.getId());
        console.log('Name: ' + profile.getName());
        console.log('Image URL: ' + profile.getImageUrl());
        console.log('Email: ' + profile.getEmail());

      , (errorany) => 
        alert(JSON.stringify(error, undefined, 2));



    (<any>window)['googleSDKLoaded'] = () => 
      (<any>window)['gapi'].load('auth2', () => 
        this.auth2 = (<any>window)['gapi'].auth2.init(
          client_id: 'YOUR CLIENT ID',
          cookiepolicy: 'single_host_origin',
          scope: 'profile email'

    (function (dsid) 
      var js, fjs = d.getElementsByTagName(s)[0];
      if (d.getElementById(id))  return; 
      js = d.createElement('script'); = id;
      js.src = "";
      fjs?.parentNode?.insertBefore(js, fjs);
    (document, 'script''google-jssdk'));

Step 4: Update the app / app.component.html file.

    transitionbackground-color .3sbox-shadow .3s;
    padding12px 16px 12px 42px;
    box-shadow0 -1px 0 rgba(0, 0, 0, .04)0 1px 1px rgba(0, 0, 0, .25);

    background-position12px 11px;

Step 5: Run the angular application.

To run the Angular application, you have to write the following command:

ng serve

Let’s open your browser, type the following URL in the address bar and check the output of the application.
