Laravel 8 Firebase Phone Number OTP Auth Example

In this step by step tutorial I will demonstrate you with example to add mobile number OTP verification using firebase in laravel. Please follow the instruction given below:

Step 1 – Download Laravel 8 Application
Step 2 – Connecting App to Database
Step 3 – Create View

Step 4 – Create Route
Step 5 – Create Controller By Artisan Command
Step 6 – Run Development Server

Before you start with this tutorial you need to visit Firebase Console and create a project. then you have to create web app on that project with phone number auth enabled in authentication tab.

Step 1 – Download Laravel 8 Application

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

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

1	composer create-project --prefer-dist laravel/laravel blog

Step 2 – Connecting App to Database

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database-name
DB_USERNAME=database-user-name
DB_PASSWORD=database-password

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=database-name

DB_USERNAME=database-user-name

DB_PASSWORD=database-password

Step 3 – Create View

In this step we will create blade view file. Go to resources/views directory and create one blade view file index.blade.php. And then add the following code into it:

<html>
<head>
<title>Laravel 8 Phone Number Authentication using Firebase</title>
<!-- CSS only -->
<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta2/dist/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
</head>
<body>
<div class="container">
<h1>Laravel 8 Phone Number Authentication using Firebase</h1>
<div class="alert alert-danger" id="error" style="display: none;"></div>
<div class="card">
<div class="card-header">
Enter Phone Number
</div>
<div class="card-body">
<div class="alert alert-success" id="sentSuccess" style="display: none;"></div>
<form>
<label>Phone Number:</label>
<input type="text" id="number" class="form-control" placeholder="+91********">
<div id="recaptcha-container"></div>
<button type="button" class="btn btn-success" onclick="phoneSendAuth();">SendCode</button>
</form>
</div>
</div>
<div class="card" style="margin-top: 10px">
<div class="card-header">

</div>
<div class="card-body">
<div class="alert alert-success" id="successRegsiter" style="display: none;"></div>
<form>
<input type="text" id="verificationCode" class="form-control" placeholder="Enter verification code">

firebase.initializeApp(firebaseConfig);

<script type="text/javascript">

function render() {
window.recaptchaVerifier=new firebase.auth.RecaptchaVerifier('recaptcha-container');
recaptchaVerifier.render();
}
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").text(error.message);
$("#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();
}).catch(function (error) {
$("#error").text(error.message);
$("#error").show();
});
}

<h1>Laravel 8 Phone Number Authentication using Firebase</h1>

Enter Phone Number

<form>

<label>Phone Number:</label>

<button type="button" class="btn btn-success" onclick="phoneSendAuth();">SendCode</button>

authDomain: "itdemo-push-notification.firebaseapp.com",

databaseURL: "https://itdemo-push-notification.firebaseio.com",

projectId: "itdemo-push-notification",

storageBucket: "itdemo-push-notification.appspot.com",

};

firebase.initializeApp(firebaseConfig);

</script>

window.onload=function () {

render();

};

function render() {

window.recaptchaVerifier=new firebase.auth.RecaptchaVerifier('recaptcha-container');

recaptchaVerifier.render();

}

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").text(error.message);

$("#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();

}).catch(function (error) {

$("#error").text(error.message);

$("#error").show();

});

}

</script>

</body>

</html>

Step 4 – Create Routes

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

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']);

<?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']);

Step 5 – Create Controller By Artisan Command

Now, lets create a controller named FirebaseController using command given below –

php artisan make:controller FirebaseController

1	php artisan make:controller FirebaseController

Now, go to app/http/controllers and open FirebaseController.php file. And put the following code into it:

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

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FirebaseController extends Controller

{

/**

* Write code on Method

* @return response()

public function index()

{

return view('index');

}

Step 6 – Run Development Server

Now we are ready to run our example so lets start the development server using following artisan command –

php artisan serve

1	php artisan serve

Now, open the following URL in browser to see the output –

http://127.0.0.1:8000/firebase-phone-authentication

1	http://127.0.0.1:8000/firebase-phone-authentication
