As you discovered, password protection protects scripts and the ability to
copy portions of the stack.  Setting a password for the stack will not
protect it from operating.

All you need to do is create your "key" somewhere in your stack: a property,
a hidden field, whatever object you want -- let's say a custom property of
the first card called "uPass".  The simply pop an ask dialog to check, as
you already tried.  Personally, I would separate the password confirmation
from the openStack handler:

on openStack
   send "checkPermission" to me in 0.5 seconds
end openStack

on checkPermission
   ask "Enter your password:"
   if not (it=the uPass of this cd) then quit
end checkPermission
