Laravel 8 Firebase Mobile Number (OTP) Authentication Tutorial

In this tutorial im going to learn how to integrate Login with OTP Authentication in Laravel. I will create step by step simple example of firebase phone auth in laravel 8. we will create firebase app and give login with phone enable. then we will write simple code to mobile verification(opt) in laravel.

First of all create firebase Project and APP. Go through below URL and create web app on that project as like i added bellow screenshot.

FireBase

AS preview

After given name and next then you will received firebase sdk as like bellow screen shot:

Next you need to enable phone number auth from bellow link:

Authentication

You have to save that all information because we will use in our app.

Next to Install laravel Project

composer create-project --prefer-dist laravel/laravel otp

lets go to .env folder and put database name and connect to database.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=ajax-image
DB_USERNAME=root
DB_PASSWORD=

Here, we need to add one route with FirebaseController controller so let’s add that route in web.php file.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\FirebaseController;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::get('firebase-phone-authentication', [FirebaseController::class, 'index']);

Next to Create Controller Run below command

php artisan make:controller FirebaseController

Go to your controller and paste below code

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class FirebaseController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        return view('firebase');
    }
}

Next to create Blade

resources/views/firebase.blade.php

    function phoneSendAuth() {
           
        var number = $("#number").val();
          
        firebase.auth().signInWithPhoneNumber(number,window.recaptchaVerifier).then(function (confirmationResult) {
              
            window.confirmationResult=confirmationResult;
            coderesult=confirmationResult;
            console.log(coderesult);
  
            $("#sentSuccess").text("Message Sent Successfully.");
            $("#sentSuccess").show();
              
        }).catch(function (error) {

            $("#error").show();
        });
  
    }
  
    function codeverify() {
  
        var code = $("#verificationCode").val();
  
        coderesult.confirm(code).then(function (result) {
            var user=result.user;
            console.log(user);
  
            $("#successRegsiter").text("you are register Successfully.");
            $("#successRegsiter").show();
