Custom Login in LARAVEL [Single user]

First Step is to create a project and connect it to the database and run the migration.And See the usertable It is created automatically and check if the following fields are there or not

Schema::create('users', function (Blueprint $table) {
    $table->id();
    $table->string('name');
    $table->string('email')->unique();
    $table->string('password');
    $table->timestamps();
});

Run the migration if needed..  ->  php artisan migrate

Now create AuthController  php artisan make:controller AuthController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use App\Models\User;

class AuthController extends Controller
{
    // Show login form
    public function showLoginForm() {
        return view('auth.login');
    }

    // Handle login
    public function login(Request $request) {
        $request->validate([
            'email' => 'required|email',
            'password' => 'required',
        ]);

        $credentials = $request->only('email', 'password');

        if (Auth::attempt($credentials)) {
            $request->session()->regenerate();
            return redirect()->intended('/dashboard');
        }

        return back()->withErrors([
            'email' => 'Invalid credentials',
        ]);
    }

    // Logout
    public function logout(Request $request) {
        Auth::logout();
        $request->session()->invalidate();
        $request->session()->regenerateToken();
        return redirect('/login');
    }

    // Show registration form
    public function showRegisterForm() {
        return view('auth.register');
    }

    // Handle registration
    public function register(Request $request) {
        $request->validate([
            'name' => 'required|string|max:255',
            'email' => 'required|email|unique:users,email',
            'password' => 'required|min:6|confirmed',
        ]);

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

        Auth::login($user);

        return redirect('/dashboard');
    }
}

you can write the  login and registration form like this as well

This is register function


public function register(Request $request)
{
    $credentials = $request->validate([
        'name' => 'required|string|max:255',
        'email' => 'required|email|unique:users,email',
        'password' => 'required|min:6|confirmed',
    ]);

    $credentials['password'] = Hash::make($credentials['password']);

    $user = User::create($credentials);

    Auth::login($user);

    return redirect('/dashboard');
}


This is login function
public function login(Request $request)
{
    $credentials = $request->validate([
        'email' => 'required|email',
        'password' => 'required',
    ]);

    if (Auth::attempt($credentials)) {
        return redirect()->intended('/dashboard')->with('status', 'Logged in successfully!');
    }

    return back()->withErrors(['email' => 'Invalid credentials'])->onlyInput('email');
}

Define Routes

use App\Http\Controllers\AuthController;

// Guest routes
Route::middleware('guest')->group(function () {
    Route::get('login', [AuthController::class, 'showLoginForm'])->name('login');
    Route::post('login', [AuthController::class, 'login']);
    Route::get('register', [AuthController::class, 'showRegisterForm'])->name('register');
    Route::post('register', [AuthController::class, 'register']);
});

// Protected routes
Route::middleware('auth')->group(function () {
    Route::post('logout', [AuthController::class, 'logout'])->name('logout');
    Route::get('/dashboard', function () {
        return view('dashboard');
    });
});

Create blade view

Login: resources/views/auth/login.blade.php

@extends('layouts.app')

@section('content')
<div class="container">
    <h2>Login</h2>
    <form method="POST" action="{{ route('login') }}">
        @csrf
        <div class="mb-3">
            <label>Email</label>
            <input type="email" name="email" class="form-control" value="{{ old('email') }}" required>
        </div>
        <div class="mb-3">
            <label>Password</label>
            <input type="password" name="password" class="form-control" required>
        </div>
        @error('email')
        <div class="text-danger">{{ $message }}</div>
        @enderror
        <button type="submit" class="btn btn-primary">Login</button>
        <a href="{{ route('register') }}" class="btn btn-link">Register</a>
    </form>
</div>
@endsection

Register: resources/views/auth/register.blade.php

@extends('layouts.app')

@section('content')
<div class="container">
    <h2>Register</h2>
    <form method="POST" action="{{ route('register') }}">
        @csrf
        <div class="mb-3">
            <label>Name</label>
            <input type="text" name="name" class="form-control" value="{{ old('name') }}" required>
        </div>
        <div class="mb-3">
            <label>Email</label>
            <input type="email" name="email" class="form-control" value="{{ old('email') }}" required>
        </div>
        <div class="mb-3">
            <label>Password</label>
            <input type="password" name="password" class="form-control" required>
        </div>
        <div class="mb-3">
            <label>Confirm Password</label>
            <input type="password" name="password_confirmation" class="form-control" required>
        </div>
        <button type="submit" class="btn btn-primary">Register</button>
        <a href="{{ route('login') }}" class="btn btn-link">Login</a>
    </form>
</div>
@endsection

Dashboard: resources/views/dashboard.blade.php

@extends('layouts.app')

@section('content')
<h1>Welcome, {{ auth()->user()->name }}</h1>
<p>This is your dashboard.</p>
@endsection

5️⃣ Update layouts/app.blade.php

<!-- Sidebar and main content structure -->
<div class="container-fluid">
    <div class="row">
        <nav class="col-md-3 col-lg-2 sidebar">
            <a href="/dashboard">Dashboard</a>
            <a href="/posts/create">Create Post</a>

            @auth
            <form method="POST" action="{{ route('logout') }}">
                @csrf
                <button type="submit" class="btn btn-link p-0 mt-3">Logout</button>
            </form>
            @endauth
        </nav>

        <main class="col-md-9 col-lg-10 p-4">
            @yield('content')
        </main>
    </div>
</div>

✅ Now you have a fully functional, clean, custom auth system in Laravel 12, without Breeze or Jetstream.

• /login → login form

• /register → register form

• /dashboard → protected dashboard

• Logout works via POST form
