Multiple password entries with multiple files

[wireshop]

Designing a multiple file database. How do I prevent from entering a password each time I open a file. Right now I have a dummy file that has an "Open" script that opens all the files that the user needs to start. Although I may change this when I get my custom menu set up. Either way I don't want the user to have to enter a password more than once. Is there a way to accomplish this?

If the files have the same user/passwords as the file that opens them, they won't ask for a password.
