My statement was not meant to be ambiguous, OpenID is only authenticating
that the user *owns* the identity, not meant to be a username/password
combination. There have been several talks on this very confusion. The
sites should hold on to the passwords and should only rely on the
authentication for small stuff, comment (instead of of Captcha, or some
other hackish question).

Passport was in fact a username/password combination with single sign on
meant to be used on online store sites. OpenID is not meant to be used
more than on simple tasks, like submitting comments on blogs and small
tasks. If you want something more powerful, you'll actually need to have
the user register and have a separate password for your site which both
you and the user know.

In that last case, no it would not be a single sign on, because you negate
it with the registering and separate password. You know the user is who
they say they are (their IDentity), unless they have a server that sends
back that everyone is who they say they are (which is bad).

You would not say, replace the administration account with OpenID account,
it has far too many permissions.
