    More cargo cult password rules: making the user change their password if there were too many bad login attempts.

        This policy allows an attack without any secret to force a password change, possibly to a weaker one if user is forced to do it on the spot.

        Like almost all password rules, some twit made it up because it seemed like a good idea.

        There are often sound reasons for security things that at first seem dumb / needlessly complex. Except password policies. Usually just dumb.

        My bank did this to me 3X in a ~wk, yet wdn't tell me where the login attempts came from. To stop it I finally had to change my username. 1/

        I was trying to figure if it really was a hack attempt or just sm1 w/ similar username who was accidentally typing mine. (Yes, possible.) 2/

        My bank does this. Anyone can DoS me that way: block me out of home banking and make me *go to an ATM* to reset my password.
