Once a person has entered the password to view this means that the user is given access to the mdb that is password protected. Its like giving someone ther key to your front door. Would you expect them to have to unlock every door in your house to get into each room.
Unless you lived in prison, that is. But in prison security is the main concern. If you want to set up you system as a prison you need to look at other security methods, however if you are happy that once they get past the front door they can go into any room in the house you want them to then no further action is required.
If you have a special room that you do not want them to enter you can ask them if they have a seperate key for this room. If they have then ok, if not, go away.
