Related to that is another reason I've heard: if your password is
figured out by some means other than hash theft [1], there's a maximum
of N days to make use of it. But let's face it, if someone gets hold
of one of your accounts, it won't take long to do serious damage. Even
if it's not a high-profile target like email or banking, a service
with your password known by someone else is a problem *now*, not
"after a month of research" or something.

Password maximum age is the wrong solution to a few problems, and is
itself a problem. Don't do it.
