Authentication and Authorization use dynamic properties in the controllers, like this for example:

```auto
        $this->Authentication->addUnauthenticatedActions(['display']);

```

But PHPStan is obviously not happy with this:

```auto
Access to an undefined property App\Controller\PagesController::$Authorization. 

```

How can i handle this, so PHPStan is happy with it?

Add property annotations above the AppController like so:

```php
/**
 * Application Controller
 *
 * @property \Authentication\Controller\Component\AuthenticationComponent $Authentication
 * @property \Authorization\Controller\Component\AuthorizationComponent $Authorization
 */
class AppController extends Controller
{
    // Rest of the AppController
}

```

But I’d rather recommend you take a look at [GitHub - dereuromark/cakephp-ide-helper: IDE Helper plugin for CakePHP](https://github.com/dereuromark/cakephp-ide-helper) which can automatically add those annotations (and many others) to your code.

Also (for higher stan levels) you will need [GitHub - CakeDC/cakephp-phpstan: CakePHP 4 extension for PHPStan](https://github.com/CakeDC/cakephp-phpstan)
