You're asking quite a reasonable question. If you use one of the alternate
authentication systems (like LoginManager or Generic User Folder), you can
make a login scheme that uses cookies with a custom login screen. I'm hoping
to soon have a package that works with LoginManager to be a little more plug
and play.

The way it works is pretty straightforward. You just set the permissions
such that the user would have to authenticate in order to view that data.
Zope's authentication machinery will kick in, and LoginManager would then
put your login screen up.
