integrating login/password fields into WP-CRM forms?

I know when it comes to WordPress & coding I’m in over my head but how can I create fields within a CRM form that become the ‘user login’ and initial assigned ‘password’ so that new members can log in the next time they visit the site (and reset their passwords to whatever they want at that time)? Is is a simple matter of just assigning the right slugs to the data fields and if so what are they?

Thank you.
