Use this code in app controller in beforefilter();

AuthComponent::$sessionKey = 'Auth.User';
  if ($this->request->is('post') && $this->action == 'login') {
      $username = $this->request->data['User']['email'];
      if (filter_var($username, FILTER_VALIDATE_EMAIL)) {
          $this->Auth->authenticate = array(
                  'Form' => array(
                      'fields' => array(
                          'username' => 'email', //Default is 'username' in the userModel
                          'password' => 'password'), //Default is 'password' in the userModel
                      // 'scope'=>array('User.status' => '1'),
                      'userModel' => 'User'
                  )
              );
      }else{
       $this->Auth->authenticate['Form']['fields']['email'] = 'mobile';
          $this->request->data['User']['mobile'] = $username;
          unset($this->request->data['User']['email']);
    $this->Auth->authenticate = array(
                  'Form' => array(
                      'fields' => array(
                          'username' => 'mobile', //Default is 'username' in the userModel
                          'password' => 'password'), //Default is 'password' in the userModel
                      // 'scope'=>array('User.status' => '1'),
                      'userModel' => 'User'
                  )
              );

      }
  }

$this->request->data['User']['email'] is my form field in which I am sending email or mobile.
