After confirming your email address, you must register your computer. Computer registration matches your User ID with your computer. For security purposes, your User ID must be registered to each computer you use when logging in. This helps prevent access by unauthorized users.
When you log in from a registered computer, you will not be required to register again. However, if you log in from an unregistered computer in the future, you will be asked to complete a quick registration process.
Certain common events may also require you to re-register your computer, including:
Using a different internet browser. For example, you might have two different browsers on your computer, and your first login used a different browser.
Clearing the browser cookies, cache, or temporary files. Consult your browser's online help concerning temporary files and cookies to ensure that computer registration cookies are retained.
Software or hardware profile changes. If your computer has a new hard drive since your last login, the registration with your User ID may not have been retained.
Note: If you use a public or shared computer, you should close all browsers and clear the cookies after you log out to ensure security.
