currently uses it.
It is called OpenID and is explained here:
Actually, as the web site says, this is a decentralized identity
system, not a single-sign-on system. You do have to log in for
each host you visit, although you do so with just your URL instead
of a username/password pair. I haven't looked at the protocol
in depth, so there may be other really significant differeces too.
I agree that OpenID isn't an *alternative* to SSO's like CoSign or
PubCookie, I can easily imagine using a site's CoSign system as the
authentication mechanism to supply identity information to the sites
OpenID server. In this scenario, UMich might run an OpenID server,
and when visiting a site that uses OpenID (like livejournal), a UMich
person wouldn't need to create an additional account.
