Automation for in MS access

Below is my requirement. I want to make MS access automated to assign files to quality QC ers whoever active in the data base. Files should not be assigned to any Qc ers who is inactive. I want the the QC ers name should be selected automatically and this is based on the login status of the QC ers, so I want a login form where all makers have a same password and other same password for QC ers. The QC ers have should not have access to Maker working form and same for Makers should not have any access to QCer form. And there should be a admin login where the automatically assigned QC ers name can be changed if required. So my final goal is to remove the assigning form from this data base.
