No, not in the current version. Sprwt has leftover code for a Facebook login callback (/loginwith/facebook), but the model method it calls to actually verify the Facebook token and log the customer in (loginWithFacebook) is hard-disabled — it returns nothing usable as its very first line, before any of the login logic runs, so the flow cannot successfully log anyone in even if a page linked to it. On top of that, none of the standard themes show a Login with Facebook button anywhere. There is no Google sign-in option at all — no code for it exists. If you want social login, you would need to ask Sprwt support, since neither option currently works out of the box.
