继续认识OpenID——Benefits of OpenID (转自http://openid.net/get-an-openid/individuals/)

OpenID is the fast, easy and secure way to sign in to websites. Here are just a few benefits to using OpenID.

Accelerate Sign Up Process at Your Favorite Websites

Most websites ask for an extended, repetitive amount of information in order to use their application. OpenID accelerates that process by allowing you to sign in to websites with a single click. Basic profile information (such as your name, birth date and location) can be stored through your OpenID and used to pre-populate registration forms, so you spend more time engaging with a website and less time filling out registration pages.

Reduce Frustration Associated with Maintaining Multiple Usernames and Passwords

Most web users struggle to remember the multiple username and password combinations required to sign in to each of their favorite websites, and the password recovery process can be tedious. But using the same password at each of your favorite websites poses a security risk. With OpenID, you can use a single, existing account (from providers like Google, Yahoo, AOL or your own blog) to sign in to thousands of websites without ever needing to create another username and password. OpenID is the safer and easier method to joining new sites.

Gain Greater Control Over Your Online Identity

OpenID is a decentralized standard, meaning it is not controlled by any one website or service provider. You control how much personal information you choose to share with websites that accept OpenIDs, and multiple OpenIDs can be used for different websites or purposes. If your email (Google, Yahoo, AOL), photo stream (Flickr) or blog (Blogger, Wordpress, LiveJournal) serves as your primary online presence, OpenID allows you to use that portable identity across the web.

Minimize Password Security Risks

Many web users deploy the same password across multiple websites. And since traditional passwords are not centrally administered, if a security compromise occurs at any website you use, a hacker could gain access to your password across multiple sites. With OpenID, passwords are never shared with any websites, and if a compromise does occur, you can simply change the password for your OpenID, thus immediately preventing a hacker from gaining access to your accounts at any websites you visit.

Because the focus of most OpenID providers (such as Google, Yahoo and AOL) is in identity management, they can be more thorough about protecting your online identity. Most website operators are less likely to be as dedicated to protecting your identity as the OpenID providers, whose focus is on securely hosting user identities.
