With all the security scares in the news, people are scrambling to change their passwords. So, here's my take on the subject. In fact, this is what I did/do in my own life. First, separate all your logins into three categories: the critical ones, the important ones and everything else. The distinction between these categories is the amount of aggravation and losses you would suffer if a malicious person were to steal your login and completely take over your account.
