Joomla Login Module or Hikashop Login Module? Where is ReCAPTCHA?

-- HikaShop version -- : 3.0.0
-- Joomla version -- : 3.6.5
-- PHP version -- : 5.6

If I use Joomla Login Module to login or create new accound then I found more or less the same form in checkout.
But there is a big issue. With Hykashop Login at Checkout there there is any reCAPTCHA and this lack is not very safe.

Instead If I use Joomla Login Modul I can use ReCaptcha ma then I have the same form in checkout.

If I enalbe joomla login and publish it, somewhere, then at the checkout I have another login form (Hikashop).
I don't understand If I can manage the login without enabled joomla login because otherwise I have double function (hikashop login/registration form and Joomla login login/registration form)
