Online Passwords : Web sites have a variety of policies that govern how you can access your account and change your password. Look for a link (such as "my account") somewhere on the site’s home page that goes to a special area of the site that allows password and account management.
Computer Password: The Help files for your computer operating system will usually provide information about how to create, modify, and access password-protected user accounts, as well as how to require password protection upon startup of your computer. You can also try to find this information online at the software manufacturer’s Web site. For example, if you use Microsoft Windows XP, online help can show you how to manage passwords, change passwords, and more.
