Nama pengguna atau kata sandi selalu salah.- Yii2

Saya telah menginstal aplikasi tingkat lanjut Yii2, saya menyesuaikan pendaftaran sesuai dengan database pengguna saya. Setelah mendaftar saya mencoba login dan tertulis "Incorrect username or password", kata sandi saya qwerty juga saya sudah memeriksanya berkali-kali dan masih tidak berhasil.

Model pendaftaran

class SignupForm extends Model
{
public $username;
public $email;
public $password;
public $first_name;
public $middle_name;
public $last_name;
public $contact;
public $birth_date;
public $type;
public $external_type;
public $status;
public $region_id;
public $barangay_id;
public $province_id;
public $city_municipal_id;


/**
 * {@inheritdoc}
 */
public function rules()
{
    return [
        ['username', 'trim'],
        ['username', 'required'],
        ['username', 'unique', 'targetClass' => '\common\models\User', 'message' => 'This username has already been taken.'],
        ['username', 'string', 'min' => 2, 'max' => 255],

        ['email', 'trim'],
        ['email', 'required'],
        ['email', 'email'],
        ['email', 'string', 'max' => 255],
        ['email', 'unique', 'targetClass' => '\common\models\User', 'message' => 'This email address has already been taken.'],

        ['password', 'required'],
        ['password', 'string', 'min' => 6],

        ['first_name', 'required'],
        ['first_name', 'string', 'max' => 45],

        ['middle_name', 'string', 'max' => 45],

        ['last_name', 'required'],
        ['last_name', 'string', 'max' => 45],

        ['contact', 'required'],
        ['contact', 'string', 'max' => 11],

        ['birth_date', 'required'],

        ['type', 'required'],
        ['type', 'string', 'max' => 45],

        ['external_type', 'string', 'max' => 45],

        ['status', 'string', 'max' => 45],

        ['region_id', 'required'],
        ['barangay_id', 'required'],
        ['province_id', 'required'],
        ['city_municipal_id', 'required'],
    ];
}

/**
 * Signs user up.
 *
 * @return User|null the saved model or null if saving fails
 */
public function signup()
{
    if (!$this->validate()) {
        return null;
    }

    $user = new User();
    $user->username = $this->username;
    $user->email = $this->email;
    $user->setPassword($this->password);
    $user->generateAuthKey();

    $user->first_name = $this->first_name;
    $user->middle_name = $this->middle_name;
    $user->last_name = $this->last_name;
    $user->contact = $this->contact;
    $user->birth_date = $this->birth_date;
    $user->type = $this->type;
    $user->external_type = $this->external_type;
    $user->status = $this->status;
    $user->region_id = $this->region_id;
    $user->barangay_id = $this->barangay_id;
    $user->province_id = $this->province_id;
    $user->city_municipal_id = $this->city_municipal_id;

    return $user->save() ? $user : null;
}
}

Di mana kesalahan saya di sini? Ini membingungkan. Saya pikir tidak ada yang salah dalam kode saya karena saya mengikuti pengaturan instalasi Aplikasi Yii2 Advanced yang benar.

Model Masuk

public function login()
{
    if ($this->validate()) {
        return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600 * 24 * 30 : 0);
    }

    return false;
}
