$this->loadComponent('RequestHandler');
$this->loadComponent('Flash');
$this->loadComponent('Auth', [
'loginRedirect' => [

{
if ($this->request->is('post')) {
$user = $this->Auth->identify();
if ($user) {
$this->Auth->setUser($user);
return $this->redirect($this->Auth->redirectUrl());
}
$this->Flash->error(__('Invalid username or password, try again'));
}
}

change this in your AppController.php :
'authenticate' => [
'Form' => [
'fields' => ['username' => 'email', 'password' => 'password']
],
