One-time passwords (OTPs) offer an additional layer of security, commonly employed for user authentication. This article delves into the process of sending OTPs via email, utilizing Laravel’s email functionality, and harnessing Redis for efficient OTP storage and retrieval.
Required Conditions
Before we commence, please ensure that you have the following set up.
A Laravel application, with a minimum version of 5.8 or above, is required.
Redis installed and configured with your Laravel application.
An email service or SMTP server configured in Laravel.
Step 1: Set Up Laravel Project
If you have not created a Laravel project yet, please use the following command.
composer create-project laravel/laravel send-otp
cd send-otp
Step 2: Configure Mail and Redis
Update your .env file with the required configurations for mail and Redis.
MAIL_MAILER=smtp
MAIL_HOST=your mail host
MAIL_PORT=your mail port
MAIL_USERNAME=your mail username
MAIL_PASSWORD=your mail password
MAIL_ENCRYPTION=tls
REDIS_HOST=127.0.0.1
REDIS_PASSWORD=your redis password
REDIS_PORT=6379
Replace placeholders with your actual mail and Redis configurations.
Step 3: Create a Controller
Generate a controller to handle OTP-related logic.
php artisan make:controller OtpController
Update the controller with the following code.
<?php
namespace App\Http\Controllers;
use Illuminate\Support\Facades\Mail;
use Illuminate\Support\Facades\Redis;
use App\Mail\OtpMail;
use Illuminate\Http\Request;
class OtpController extends Controller
{
/**
* write code for.
*
* @param \Illuminate\Http\Request
* @return \Illuminate\Http\Response
* @author <>
*/
public function sendOtp(Request $request)
{
$email = $request->input(‘email’);
$otp = rand(100000, 999999);
Redis::setex(“otp:$email”, 300, $otp);
Mail::to($email)->send(new OtpMail($otp));
return response()->json([‘message’ => ‘OTP sent successfully’]);
}
}
This controller is responsible for generating a random 6-digit OTP, storing it in Redis with a 5-minute expiration, and subsequently sending it to the provided email address.
Step 4: Create a Mailable
Generate a Mailable for the OTP email.
php artisan make:mail OtpMail
Please update the generated Mailable (OtpMail.php located in the app/Mail directory) with the following code.
<?php
namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;
class OtpMail extends Mailable
{
use Queueable, SerializesModels;
public $otp;
/**
* Create a new message instance.
*
* @return void
*/
public function __construct($otp) {
$this->otp = $otp;
}
/**
* Build the message.
*
* @return $this
*/
public function build()
{
return $this->view('emails.otp');
}
}
Step 5: Create an Email View
Create an email view file at resources/views/emails/otp.blade.php and populate it with the following content.
<!DOCTYPE html>
<html>
<head>
<title>One-Time Password</title>
</head>
<body>
<h1>Your OTP is: {{ $otp }}</h1>
</body>
</html>
This view will display the OTP in the email.
Step 6: Update Routes
Update your web.php routes file to include a route for sending OTP.
use App\Http\Controllers\OtpController;
Route::post(‘/send-otp’, [OtpController::class, ‘sendOtp’]);
Step 7: Test the Implementation
Initiate your Laravel development server by running the following command.
php artisan serve
Send a POST request to http://127.0.0.1:8000/send-otp with an email parameter.
curl -X POST -d “email=test@gmail.com” http://127.0.0.1:8000/send-otp
Please check your email inbox for the OTP.
I hope it can help you...
