One password for all your Internet needs. Wouldn't that be great? How many social networking sites did you say you belong to? Do you use the same username and password on all of them or do you have to remember different ones for different sites? Wouldn't it be nice if you didn't have to remember any of them anymore?

With OpenID you will only have to remember one username and password and you will be logged into all your sites. You also won't have to register for sites that are OpenID enabled. Just sign in and you're signed up.
