Is it possible to implement Facebook OAuth2 within Meraki Garden?

Question

OAuth

There was a need to implement Captive Portal with authorization through social networks and a regular login / password and providing free access to the Internet only after successful authorization. Everything is clear with Google+ and Vkontakte: we add accounts.google.com and oauth.vk.com to the Walled garden ranges and authorization is probably secured. It's more complicated with Facebook and LinkedIn: they have OAuth entry points located on the main domains, so. it is not possible to add them to Walled garden ranges while retaining access to the authorization pages.
Has anyone gotten out of a similar situation?

Answer 1

I found a solution: by clicking "Login with Facebook" you can open full access to the Internet for a while so that the user has time to complete the authorization.
