'password' => Hash::make($password)
```

```

<!-- Semua form dilindungi CSRF token -->
<form method="POST">
    @csrf
</form>
```

### **4. Middleware Protection**
```php
// Protected routes
Route::middleware(['auth'])->group(function () {
    // Admin routes here
});

// Guest routes
Route::middleware(['guest'])->group(function () {
    // Login/register routes here
});
```

---

## 🧪 **TESTING**

### **Test 1: Login dengan Credentials Benar**

```bash
# Via cURL
curl -X POST http://127.0.0.1:8000/login \
  -d "email=admin@admin.com" \
  -d "password=password"
```

**Expected:** Redirect ke dashboard

---

### **Test 2: Login dengan Credentials Salah**

```bash
curl -X POST http://127.0.0.1:8000/login \
  -d "email=admin@admin.com" \
  -d "password=wrongpassword"
```

**Expected:** Error message "credentials do not match"

---

### **Test 3: Access Protected Route Tanpa Login**

```bash
curl http://127.0.0.1:8000/licenses
```

**Expected:** Redirect ke /login

---

### **Test 4: Logout**

```bash
curl -X POST http://127.0.0.1:8000/logout \
  -H "Cookie: laravel_session=..."
```

**Expected:** Redirect ke /login

---

## 🚀 **PRODUCTION SETUP**

### **1. Change Default Password**

⚠️ **PENTING:** Ubah password default sebelum production!

```bash
php artisan tinker
```

```php
$admin = User::where('email', 'admin@admin.com')->first();
$admin->password = Hash::make('your_strong_password_here');
$admin->save();
```

### **2. Disable Register Page**

Register page sudah otomatis disabled setelah ada 1 admin.

Untuk disable permanent, comment di `routes/web.php`:

```php
// Route::get('register', [AuthController::class, 'showRegister'])->name('register');
// Route::post('register', [AuthController::class, 'register'])->name('register.post');
```

### **3. Update .env**

```env
SESSION_LIFETIME=120           # 2 hours
SESSION_SECURE_COOKIE=true     # HTTPS only
```

---

## 📱 **MOBILE RESPONSIVE**

Login page sudah responsive:
- ✅ Desktop (1920x1080)
- ✅ Tablet (768x1024)
- ✅ Mobile (375x667)
