My job makes us change passwords every mumblemumble months, and seemingly every time, there's a new policy: must use uppercase and lowercase letters. Must include letters and numbers and special characters. Must not have been used in last two password changes. Must include DNA sample and ranked order of least favorite to most favorite Beatles albums. And so forth. I hate Password Changing Day even more than I hate Daylight Savings Time, because it throws me off every time I have to enter a password, which is ten or twelve times a day, sometimes more.
This person thinks she has a better concept. What if you could have a color, or a shape, or series of shapes, as your password?
I know that the notion of forcing users to change default passwords is, for some unfathomable reason, controversial, but if a password were to be changed from default, then I should think that making a password both difficult to guess and easy to remember would be a good thing.
