Several years ago I worked at a place where users had to change their windows
password every N month and they kept a long history log of used password.
My solution to this was to write a program that asked me for my current
password and how many previous used password the system remembered. The
program worked like this:
for (n = 0; no_of_stored_password > n; n++) {
set_password(random_generated_password);
do_a_short_sleep();
}
set_password(original_password);
... and the problem was solved :)
