Actually, it is implied in PoA that it is the portrait that covers 
the entrance that sets the password. Sir Cadogan (who takes over for 
the Fat Lady when she is attacked by Sirius Black) keeps making up 
such difficult ones (like "Scurvy cur" and "Odsbodkins") that Neville 
asks for the week's in advance, which leads to Sirius to be able to 
get into the tower. Though admittedly there is no portrait over the 
Slytherin common room door, perhaps the wall is enchanted to choose 
passwords.
