OpenID

I have registered for an OpenID at this website, www.myopenid.com. This OpenID can be used at some websites that have implemented this facility. More websites are expected to have this option in the future.

By using an OpenID, I do not have to provide a login name and password to the "relying website". They will accept my OpenID.

Apart from the service provider that I happen to use, there are many other websites a similar facility.
