This is a big one. Especially in corporate environments where most of the users are, shall we say, not tech savvy. Forcing people to comply with byzantine incomprehensible password composition rules plus incessantly insisting that they change their password every 7/14/30 days to a new inscrutable string that looks like somebody sneezed in punctuation marks accomplishes nothing other than enticing everyone to just write their password down on a Post-It and stick it to their monitor or under their keyboard.
Remember: Users do not care about passwords. From the perspective of anyone who isn't a programmer or a security expert, passwords are just yet another exasperating roadblock some nerd keeps putting in front of them that is preventing them from doing whatever it is they were actually trying to do.
That works great until some dickhole implements the old, "New password cannot contain any sequence from your previous (5) passwords."
This also of course necessitates storing (multiple successive!) passwords in plain text or with a reversible cipher, which is another stupid move. You'd think we'd have gotten all of this out of our collective system as a society by now, and yet I still see it all the time.
All of these schemes are just security theater, and actively make the system in question less secure while accomplishing nothing other than berating and frustrating its users.
This also leads to stupid rules like you can’t change your password more than once a day, to prevent someone from changing their password 5 times and then changing it back to what it was before.
"I just increment the number at the end" is a phrase I've heard so many times
