In this post, I am going to explain about login with Magic Link in LARAVEL 9.

After [Installing Laravel](https://dev.to/shanisingh03/how-to-install-laravel-9-25c4) and [Laravel Authentication](https://dev.to/shanisingh03/how-to-make-login-registration-in-laravel-9-1p2n) open code project in code editor & follow the steps below.

## Step -1
To make password less login with Magic Link, we are going to us [Laravel Password Less](https://github.com/grosv/laravel-passwordless-login) Package.

All you need to do is run the composer command.

```php
composer require grosv/laravel-passwordless-login
```

## Step - 2
Make Changes in login view file, open `resources/views/auth/login.blade.php` and update the code below.

```php
@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div class="card-header">{{ __('Login') }}</div>

                <div class="card-body">
                    <form method="POST" action="{{ route('login') }}">
                        @csrf

                        @if (session('message'))
                            <div class="alert alert-info">{{ session('message') }}</div>
                        @endif

                        <div class="row mb-3">
                            <label for="username" class="col-md-4 col-form-label text-md-end">{{ __('Username') }}</label>

                            <div class="col-md-6">
                                <input id="username" type="text" class="form-control @error('username') is-invalid @enderror" name="username" value="{{ old('username') }}" required autocomplete="username" autofocus>

                                @error('username')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="row mb-3">
                            <label for="password" class="col-md-4 col-form-label text-md-end">{{ __('Password') }}</label>

                            <div class="col-md-6">
                                <input id="password" type="password" class="form-control @error('password') is-invalid @enderror" name="password"  autocomplete="current-password">

                                @error('password')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="row mb-3">
                            <div class="col-md-6 offset-md-4">
                                <div class="form-check">
                                    <input class="form-check-input" type="checkbox" name="remember" id="remember" {{ old('remember') ? 'checked' : '' }}>

                                    <label class="form-check-label" for="remember">
                                        {{ __('Remember Me') }}
                                    </label>
                                </div>
                            </div>
                        </div>

                        <div class="row mb-0">
                            <div class="col-md-8 offset-md-4">
                                <button type="submit" name="submit" class="btn btn-primary" value="login">
                                    {{ __('Login') }}
                                </button>

                                or

                                <button type="submit" class="btn btn-secondary" name="submit" value="magic-link">
                                    {{ __('Send Magic Link') }}
                                </button>
                            </div>
                        </div>

                        <div class="row mb-0 mt-3">
                            <div class="col-md-8 offset-md-4">

                                    <a class="btn btn-link" href="{{ route('password.request') }}">
                                        {{ __('Forgot Your Password?') }}
                                    </a>
                                @endif

                                <a class="btn btn-link" href="{{ route('otp.login') }}">
                                    {{ __('Login With OTP.') }}
                                </a>
                            </div>
                        </div>
                    </form>
                </div>
            </div>
        </div>
    </div>
</div>
@endsection
```

## Step - 3
Update the `app/Http/Controllers/Auth/LoginControlller.php` add the login & Login with Magic Link Function.

```php
<?php

namespace App\Http\Controllers\Auth;

use App\Models\User;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Notifications\SendMagicLinkNotification;
use App\Providers\RouteServiceProvider;
use Illuminate\Foundation\Auth\AuthenticatesUsers;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = RouteServiceProvider::HOME;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    public function username()
    {
        return 'username';
    }

    public function login(Request $request)
    {

        
        if($request->input('submit') == 'magic-link'){
            $user = $this->loginViaMagicLink($request);

            if(!$user){
                return redirect()->route('login')
                ->withErrors(['username' => 'User with this username does not exist.'])
                ->withInput();
            }

            return redirect()->route('login')
            ->withMessage('Magic Link Sent to the registered email ID.');
        }

        $this->validateLogin($request);

        // If the class is using the ThrottlesLogins trait, we can automatically throttle
        // the login attempts for this application. We'll key this by the username and
        // the IP address of the client making these requests into this application.
        if (method_exists($this, 'hasTooManyLoginAttempts') &&
            $this->hasTooManyLoginAttempts($request)) {
            $this->fireLockoutEvent($request);

            return $this->sendLockoutResponse($request);
        }

        if ($this->attemptLogin($request)) {
            if ($request->hasSession()) {
                $request->session()->put('auth.password_confirmed_at', time());
            }

            return $this->sendLoginResponse($request);
        }

        // If the login attempt was unsuccessful we will increment the number of attempts
        // to login and redirect the user back to the login form. Of course, when this
        // user surpasses their maximum number of attempts they will get locked out.
        $this->incrementLoginAttempts($request);

        return $this->sendFailedLoginResponse($request);
    }

    public function loginViaMagicLink(Request $request)
    {
        $user = User::where('username', $request->input('username'))->first();

        if ($user) {
            $user->notify(new SendMagicLinkNotification());
        }

        return $user;
    }
}
```

## Step - 4 
Create notification to send magic link on registered email.

```php
php artisan make:notification SendMagicLinkNotification
```

After creating the notification open it from `app/Notifications` and update the code below.

```php
<?php

namespace App\Notifications;

use Grosv\LaravelPasswordlessLogin\LoginUrl;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Notifications\Notification;

class SendMagicLinkNotification extends Notification
{
    use Queueable;

    /**
     * Create a new notification instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Get the notification's delivery channels.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function via($notifiable)
    {
        return ['mail'];
    }

    /**
     * Get the mail representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return \Illuminate\Notifications\Messages\MailMessage
     */
    public function toMail($notifiable)
    {

        $generator = new LoginUrl($notifiable);
        $generator->setRedirectUrl('/home');
        $url = $generator->generate();

        return (new MailMessage)
                    ->subject('Your Login Magic Link!')
                    ->line('Click this link to log in!')
                    ->action('Login', $url)
                    ->line('Thank you for using our application!');
    }

    /**
     * Get the array representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function toArray($notifiable)
    {
        return [
            //
        ];
    }
}
```

That's it now you visit on login page and you will see the magic link button on login page.


![Login](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/min9bktz43xy1bnt0sex.png)

After you hit send magic link you are going to get email like.

I hope this will help login with `MAGIC LINK` in LARAVEL 9.
