Windows CardSpace lets you store user account information for online services that support the CardSpace feature. It’s a means of creating a digital identity that can be used instead of a username and password to log in to online accounts that support the CardSpace feature. CardSpace adds security to Web relationships by encrypting data in your card before sending the information to a Web site. You can also review cards from Web sites that use them to get more information about a site before signing up for an account.
CardSpace is still relatively new, with a limited number of Web sites supporting it. The idea of CardSpace is fairly simple, however. You can create one or more digital cards, each with whatever information you want to provide to Web sites with which you do business. For example, you might want cards that include only your name and no further identifying information. Other cards might include your street address and phone number.
When you set up an account with an online site that supports CardSpace, you can send your card rather than fill in blanks on that site’s user form. After you’ve established an account, you can submit your card whenever you need to log in to the site.
You can choose from two kinds of cards to use:
• Personal cards: These you create yourself and provide to online Web services as you see fit.
• Managed cards: These are like membership cards provided to you by organizations and businesses that support the CardSpace identity system.
Use one of the following methods to access Windows CardSpace:
• Click the Start button and choose Control Panel -> User Accounts and Family Safety Windows CardSpace.
• Tap [windows], type card and click Windows CardSpace.
If you’re taken to a welcome page, click OK to proceed. To create a personal card, click Add a Card in the right column. Click Personal Card and fill in whatever blanks you’re comfortable with. You might want to start by creating a basic card that contains your name, e-mail address, and perhaps a picture or logo. You can create other cards with more information, if necessary, for sites that you trust with that information.
You don’t create managed cards yourself. Instead, you set up an account with a service that uses managed cards. When you receive such a card, you’ll likely get instructions on its use. But the basic procedure is to go into CardSpace, click Add a Card, click Install a Managed Card, and then import the card that the online service has sent you.
If the CardSpace technology catches on, you’ll be able to access your cards right from your Web browser. When you go to log in to a site, you’ll see an option to log in the traditional way through a user account and password, or by using CardSpace (or an InfoCard). Click the option to use CardSpace, click the card you want to use, and you’re logged in.
