How do you use Yii’s built-in authentication and authorization features?

Answer: In Yii, you can use built-in authentication and authorization features through its user component (`Yii::$app->user`) and RBAC (Role-Based Access Control).

1. Authentication: Implement user login with `LoginForm` model, leveraging `User::findByUsername` to validate credentials. Use `User::login()` to create a session upon successful login.

2. Authorization: Define roles and permissions using the RBAC system. You can create roles and permissions in migration or controller using `yiirbacDbManager`. Use `Yii::$app->authManager->assign()` to assign roles and check permissions with `Yii::$app->user->can()`.

Combine these features to control user access throughout your application.
