It depends on the threat vector, though. Printing out my passwords in 72-pt font and taping them to the wall is obviously insecure if I leave them up for the house cleaner to see, but there's zero risk that a remote attacker will see them (barring them taking over the webcam or something, but at that point they probably have root access anyway).
