Reasoning appreciated. > Well, I don't know of any, but where I am currently working, there seems to be a case where password aging has decreased the general level of security. Why? Well, there's a lot of networking going on, and many people find themselves with accounts on 10 or 15 or 50 machines, each of which has to have a password. Password aging has been installed on some of them, so periodically users find themselves being harassed by yet another system that wants them to change their password. After a while, we all find that we have a whole lot of different passwords, and there's only one way that a mere human can possibly remember them: write them down on paper along with the hostnames.
