There’s nothing in the OpenID protocol that would really allow this, especially from the data side of things. Unlike, say, credit cards, where you can transfer your balance between different providers, data transfer between different OPs requires a bit more leg work.
What kind of data are you talking about?teohhanhui commented
A user should be able to merge multiple OpenID identities, such that the endpoints are mutually aware of the user's identity and can cross-authenticate when queried by an OpenID consumer. As it currently stands users are left with separate identities without a way of unifying them. Having the OpenID consumer store the different OpenID identities to be associated with a user account is inelegant.teohhanhui supported this idea ·
