You views on Bitcard SSO?

[Andy Selby]

Is bitcard.org a good single sign on service or should I use Oauth?
There is very little on the web[1] and none of it is recent.

I'm looking into an authentication framework for MK Makerspace so the
members section, wiki and hackernews-like section can all be SSO

[1] except bitcard.org this is all I could find:

Thanks in advance
