Yii2 global filter/behavior to force user to authenticate first

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' => ['@'],
        ],
    ],
],
