their passwords every ninety days doesn't teach good computer hygiene,
it annoys them and confirms their impression that the IT people have
nothing better to do.

Hear, hear!

Hackers don't crack passwords anymore, they simply present a
socially-engineered URL for the already-authenticated user to click on
for a drive-by install of the backdoor/keylogger of his choice.
