The Hidden Door passwords are unique to each DS so someone else's passwords will not work for you
The Pandora's Box game has two hidden doors, each with their own password
You can use the related links to see what's hiding behind the doors if you do not have the first and third games in the series (these give you the passwords)
Be warned that A Ticket to Time Travel should be looked at only after completing the game's story since one of the pictures reveals a significant plot spoiler
