Please expound on these "obvious" reasons.  If I found a way to force
users to use a different password on every machine, and used it, my days
would become (more) filled with requests from users about their forgotten
passwords.  If I honor these requests by phone, I have a big security
hole.  Even worse, there would be a larger percentage of users that would
write their passwords down.   I think multiple passwords are less secure.
