Ok, so I had to add the following code below 'components' => [...]

 'as beforeRequest' => [
    'class' => 'yii\filters\AccessControl',
    'rules' => [
        [
            'actions' => ['login', 'error'],
            'allow' => true,
        ],
        [

            'allow' => true,
            'roles' => ['@'],
        ],
    ],
],

In my Yii2 application I'm trying to force all users to be authenticated. If they're not already authenticated they should be redirected to the login page.

In Yii1 I did this by creating a class that would check if a user was logged in and attaching that class to the onBeginRequest behavior in my main config file.
```
// Yii 1
'behaviors' => array(
    'onBeginRequest' => array(
        'class' => 'application.components.RequireLogin',
    )
),
```
How can I get the same behavior in Yii2? I know I can use behavior to do this, but I wan't to add this behavior to my main config file so all requests are first checked for authentication.

The working behaviors method looks like this:
```
// Yii2
public function behaviors() {
    return [
        'access' => [
            'class' => AccessControl::className(),
            'rules' => [
                [
                    'actions' => ['login', 'error'],
                    'allow' => true,
                ],
                [
                    'allow' => true,
                    'roles' => ['@'],
                ],
            ],
        ],
    ];
}
```

Hint: this code adds an behavior to the application. It doesn't have to be part of components - it must be part of the config itself. So this is why jagsler wrote below components, not in components. And 'as someNameHere' => ... is the syntax for adding behaviors. Look here for doc. I just write this because I have spend some hours finding that out.

Very nice. It saves my time.

Another note: you need to have a controller and an action site/login because this gets called if the user is not logged in and no rule applies. This can be changed in the configuration (see here for more information) if the login action has another name or is another controller.

If you exclude error from the allowed actions it causes a white screen. Previously you could use this to redirect everyone that was not logged in, however, you can no longer redirect 404 errors etc since some updates. I found the current way here github.com/yiisoft/yii2/issues/11054#issuecomment-198310042
