Is third-party SSO/OAuth2 available with Members feature?

Hey guys,

First, huge thanks to the Ghost team for the membership feature! I’ve been following this for several months, and I’m excited to see this in production!

My team is very interested in building social auth ability, (e.g. via Facebook, LinkedIn, etc.) for our platform members, although I can’t find any API docs around the ‘members’ feature specifically. Does anyone know if this is available yet -even in beta, or yet to be developed? I see that there is SSO/OAuth2 available as beta for the Ghost Pro Enterprise version, but I’m wondering about the OSS availability.
