Odoo website, Creating a signup page for external users
you can turn off db listing w/ some params in in odoo.cfg conf

db_name = mydb
list_db = False
dbfilter = mydb

auth_signup takes care of the registration, you don't need to do anything. A res.user will be created as well as a partner related to it.
The pwd is stored in the user.
How can I create a signup page in odoo website. The auth_signup module seems to do the job (according to their description). I don't know how to utilize it.

In the signup page there shouldn't be database selector
Where should I store the user data(including password); res.users or res.partner
