The OpenID protocol that is used by Stack Exchange websites has been obsolete for a while.

Is it going to be upgraded to something that is not obsolete? OpenID Connect comes to mind.


With the current global login system, the only thing SE really needs OpenID (or anything similar) for is people who log in using external credentials from Google / Facebook / etc. (and also a few historical special cases like SEDE, but those really should be fixed anyway).

So I suspect the answer is "whatever Google, Facebook and other major identity hubs will support." And Google and Facebook are already using OAuth anyway.

    I think they meant are we going to update our in-house OpenID service which is what our standard email/password logins actually use - we've used OAuth for Google, Facebook, and the like for many years. – animuson Jan 16 '17 at 5:29
