Send OTP Using Email and Redis in Laravel 10

Hi Dev,

Today, we will show you send OTP using Email and Redis in Laravel 10. This article will give you simple example of send OTP using Email and Redis in Laravel 10. Let’s discuss send OTP using Email and Redis in Laravel 10. In this article, we will implement a send OTP using Email and Redis in Laravel 10.

So let’s follow few step to create example of send OTP using Email and Redis in Laravel 10.

Step 1: Install Laravel 10

composer create-project laravel/laravel send-otp

Step 2: Configure Mail and Redis

.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 the placeholders with your actual mail and redis configuration.

Step 3: Create a Controller

php artisan make:controller OtpController

app/Http/Controllers/OtpController.php

<?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 will generate a random 6-digit OTP, store it in Redis with a 5-minute expiration and later ring the given email address.

Step 4: Create a Mailable

OtpMail.php located in the app/Mail directory

<?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

resources/views/emails/otp.blade.php

<!DOCTYPE html>
<html>
    <head>
        <title>One-Time Password</title>
    </head>
    <body>
        <h1>Your OTP is: {{ $otp }}</h1>
    </body>
</html>

Step 6: Update Routes

web.php

use App\Http\Controllers\OtpController;
Route::post(‘/send-otp’, [OtpController::class, ‘sendOtp’]);

Step 7: Run

php artisan serve
