Chapter 7. Single Log-In and Profiles: M... > Features and Considerations

Features and Considerations

One of the considerations when using single sign-on is that the Web sites you visit may support this feature but will still want to capture their own set of information about you. Although the single sign-on may speed registration by providing the basics of your profile, such as your name, birth date, state, and zip, you’ll still have to complete the remaining information that they require in order to register. So you’ll still need to half-register on all these other Web sites before you can start using the single sign-on to jump from site to site using the same username and password. Additionally, the site you jump to will still require you to enter your password. For example, logging on to MSN Hotmail and then going to eBay, you’ll still need to enter your MSN Hotmail password in order to log in to the “my eBay” section of the site. One of the benefits, though, is that you end up having fewer usernames and passwords to remember.
