Social Login (Facebook, Google etc.)?

Is it possible to integrate social login such as Facebook to accounts?

It should be, but what you plan to do? Expose Cockpit UI to end users? I think that is not the concept of a headless system.

Nope I will not expose the cockpit UI to end users. I`m trying to use cockpit as a backend for my mobile application. Users should have only access to restapi. Therefore I want them to be able to register through restapi with email but also with Facebook.

I have to go deeper how can I validate facebook access token on server side and then maybe I can even create a Facebook login addon for cockpit.
