Authenticates the current user.

public abstract yii\web\IdentityInterface\|null authenticate ( $user, $request, $response )
$user	yii\web\User
$request	yii\web\Request
$response	yii\web\Response

                public function authenticate($user, $request, $response);

challenge() public abstract method

Generates challenges upon authentication failure.

For example, some appropriate HTTP headers may be generated.

public abstract void challenge ( $response )
$response	yii\web\Response

                public function challenge($response);

The implementation should normally throw UnauthorizedHttpException to indicate authentication failure.

$response	yii\web\Response
throws	yii\web\UnauthorizedHttpException

                public function handleFailure($response);
