If you change your master password you have to change every single one
of your accounts.
If one account gets broken into you either:
1) have to store metadata to generate a new password, i.e. a counter or
something
2) have to change your master password
(1) is a no-go since most of these advertise as being explicitly
one-knowledge ("You only remember the master password") tools. Having to
remember my master password plus fifty or so counters defeats the point.
(2) is _very_ irritating for the aforementioned reason that anyone with
more than 30 accounts has to manually change every single one of them
even though only one of them has been possibly broken. There might be
ways to automate that, but even that is putting a small band-aid over a
big flaw.
