Passwords

The system that has been developed to identify people as they roam around the faceless Internet is password based. When you create an account with an online retailer, you pick a user name and password. If you sign up to use a research site, there's another password to enter. You can even use a password to protect your computer when you're away, ensuring that nobody can access the information stored there if they should happen to have physical access to your machine.

How you come up with passwords and make settings for using them can make them useful, or, if you do it wrong, not so useful.
