Does your password pass the test?

"One of the things I work on is password security. And because I'm someone who pays close attention to passwords and how people use them, I sometimes hear interesting stories. For example, a couple of my colleagues are so careful about the security of their passwords that they generate a random eight-character string, memorize it, and then use it as their password for two to three months. After that time elapses, they start the process over again and generate a new random password.

Do we all need to be that careful about our passwords? Probably not. But passwords are one of the web's most important security tools. Whether it's for your Google account, your banking center, or your favorite store, choosing a good password and keeping it safe can go a long way toward protecting your information online."
