  Now linlou:

        I was under the impression that the passwords are made up by 
the portraits that guard the common room entrances. In POA, Neville 
wrote them down in the first place because Sir Cadogen kept changing 
them and he couldn't keep up.  However, do we know one way or the 
other if all the common room entrances are guarded by portraits? I 
know in the COS movie Slytherin's was not, but does the book 
describe it at all?( Sorry, not sure where my copy is at the moment.)
If this is the case it may give us a further clue as to the extent 
of the abilities of the portraits.

 just a stray thought,
