I have heard it is also how NSA secure their personal passwords, they keep them in a little black book because there is no scalable attack to get access to them at rest.
In environments where regular rotations are required, I print off a new "biscuit" via `(date ; pwgen $PWGEN_FLAGS) | lpr`. I then append to the candidate password something of a personal identifier that only I know.
A few coworkers identified which systems allowed us to re-use passwords, fixed passwords, non expiring reset passwords, etc. warning signs with the password on the back too.
