Add an additional password to the Access bar/drop down selections

When you log into Access, you then select which function you wish to visit from the drop down box i.e. PeopleHR, FocalPoint etc. At this stage, when you click on the desired icon, it takes you straight to that function. Is there any way of adding an additional password at this stage? For example, you have logged into Access, you then click Employee and are asked for another password before PeopleHR opens.
