Run this command to migrate all the tables into the MySQL database,

php artisan migrate

Now make a notification PasswordToUserEmail.php

// Command to make notification
php artisan make:notification PasswordToUserEmail
// The notification will be generate in app/Notifications/

Write the below code inside PasswordToUserEmail.php

<?php
namespace App\Notifications;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Notifications\Notification;
class PasswordToUserEmail extends Notification
{
    use Queueable;
    private $password;
    /**
     * Create a new notification instance.
     *
     * @return void
     */
    public function __construct($password)
    {
        $this->password = $password;
    }
    /**
     * 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)
    {
        return (new MailMessage)
            ->line('Your password is: ' . $this->password)
            ->line('Note: This password is generated by the system!');
    }
    /**
     * Get the array representation of the notification.
     *
     * @param mixed $notifiable
     * @return array
     */
    public function toArray($notifiable)
    {
        return [
            //
        ];
    }
}

Make a controller UserController.php

// Command to make controller
php artisan make:controller UserController
// The controller will be generate in app/Http/Controllers/

Write the below code in UserController.php

<?php

namespace App\Http\Controllers;

use App\Models\User;
use App\Notifications\PasswordToUserEmail;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Str;

class UserController extends Controller
{
    function create()
    {
        return view('create-user');
    }

    function store(Request $request)
    {
        $request->validate(array(
            'name' => ['required'],
            'email' => ['email', 'unique:users,email'],
        ));

        $password = Str::random(16);

        $request['password'] = Hash::make($password);
        $user = User::create($request->all());

        $user->notify(new PasswordToUserEmail($password));

        return redirect()->back();
    }
}

Open the web.php file and add the following routes

<?php
use Illuminate\Support\Facades\Route;
Route::get('/', [\App\Http\Controllers\UserController::class, 'create'])->name('create');
Route::post('/store', [\App\Http\Controllers\UserController::class, 'store'])->name('store');

Now create a simple form to create a new user and send a password via email. Create a blade file in resources/views/create-user.blade.php
