Not true. OpenID is intended as a SSO technology, and makes a direct
comparison to Passport in its own FAQ[1]. The API clearly allows you to
authenticate a user entirely through a third-party OpenID provider[2].
Even registration can be partially automated, with the appropriate
extension[3]. It is implementation-dependent whether or not you permit
access to a given service based on OpenID authentication -- but that's
mostly because permission is an *authorization* issue, not an
authentication one.
