No password in HIKA Shop Registration

Hi
In my HIKA Shop Registration, there is no password field.
But I want the user to have a login to the page, when he registers in the shop.

Where I can administrate the Registration Page for HIKA shop registration?

At the moment in the configuration of HIKA at the tab checkoutthe registration params is selected on "no registration" and so I have a registration form on the shop.
When I select "registration" oder "simplified registration with password" the HIKA shop says "registration not allowed".
Why ?
Thank you
Rolandus

Ohh, thank you I'm getting old.

BUT: now there are 2 email fields but the e-mail confirmation in the HIKA params is disabled.
First there is a "name" fields - sugess it's the username?
Is it possible to take off this field?
Our users always would login with the e-mailadress (wue User ExtendedReg Conponent und Plug).
See attachment. It's in German, so it's difficult to say exactly which fields the 2 different e-mail fields are, because the label comes from the Translation file.
