Can't login with CakePHP3

I am trying to authenticate with CakePHP according to what I saw in the framework documentation.

What is happening now is that my first user, with id 1 normally enters the application, but all the users that I register now, always fail even me typing email and password correctly.

My code looks like this:

Form:

<div class="row">
  <?=$this->Form->create()?>
  <div class="form-group">
  <?=$this->Form->control('email', ['class' => 'form-control'])?>
  </div>
  <div class="form-group">
    <?=$this->Form->control('password', ['class' => 'form-control'])?>
  </div>
  <?=$this->Form->button('Entrar', ['class' => 'btn btn-info'])?>
  <?=$this->Html->link(__('Ainda não tem uma conta? Cadastre-se'), 
  ['action' => 'add']);?>
  <?=$this->Form->end()?>
</div>

Login method:

 public function login()
    {
        if ($this->request->is('POST')) {

            $user = $this->Auth->identify();

            if ($user) {
                $this->Auth->setUser($user);
                $this->Flash->success(__('Bem vindo '.$this->Auth->user()['name']));
                return $this->redirect($this->Auth->redirectUrl());
            } else {
                $this->Flash->error(__('Nome de usário ou senha incorretos'));
            }
        }
    }

and AppController conf:

$this->loadComponent('Auth', [
            'authenticate' => [
                'Form' => [
                    'fields' => [
                        'username' => 'email',
                        'password' => 'password',
                    ],
                ],
            ],
            'loginRedirect' => [
                'controller' => 'welcome',
                'action' => 'index',
            ],
            'logoutRedirect' => [
                'controller' => 'users',
                'action' => 'login',
            ],
        ]);
        $this->Auth->allow(['add']);

How are you creating the new users? Are their passwords being hashed correctly before going into the database?

In my database, all data is normal.

I’m creating the users this way:

public function add()
    {
        $user = $this->Users->newEntity();

        if ($this->request->is('POST')) {

            $userPatchEntity = $this->Users->PatchEntity($user,
                $this->request->getData());
            $userPatchEntity->balance = $userPatchEntity->salary+$userPatchEntity->extra_lace;

            if ($this->Users->save($user)) {
                $this->Flash->success('Cadastro realizado com sucesso');
                return $this->redirect(['action' => 'login']);
            } else {
                $this->Flash->error('Não foi possível realizar o seu cadastro');
            }
        }

And yes

public function _setPassword() {
    return (new DefaultPasswordHasher())->hash($password);
}
