Aspnetcore.docs: Social authentication without Identity

[ricardoromaobr]

How I read the providers to show in my login page?
When I'm using Identity I use SignInManager.GetExternalAuthenticationSchemesAsync().
But SignInManager is part of Idnetity? I'm right?

SignInManager is used in the authentication templates. See https://docs.microsoft.com/en-us/aspnet/core/security/authentication/scaffold-identity
to generate all the code and look for SignInManager

But in this case I want to use without the identity. Like the intention of the title of the documentation
Use social sign-in provider authentication without ASP.NET Core Identity. If I use SignInManager it will use the Identity. Would you complete this example to be more clear, please.

The Use cookie authentication without ASP.NET Core Identity is fantastic example, Make an example like this would be great!I can downloded and running and changed to learn with example. :)
