AspNetCore - change cookie name when using Google Authentication

Question

In ASP.NET 5, MVC 6, I was able to change the name of the external authentication cookie in the options - but that seems to be removed from the new providers in AspNetCore.Identity RC2 libraries.

I've got this setup;

class Startup {
   ...
   public void ConfigureServices(IServiceCollection services){
      services.AddIdentity<Member, Role> ... // identity wired up
   }

   public void Configure(IApplicationBuilder app, ILoggerFactory logger) {
      // .. other wiring
    app
        .UseIdentity()
        .UseGoogleAuthentication
        (new GoogleOptions {
            ClientId = Constants.Google.Client,
            ClientSecret = Constants.Google.Secret,
            Scope = {"email", "profile"}
        });

    app.UseMvc(routes => {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
         });
    }
}

There used to be an AuthenticationType property that I could set to a string and it would control the cookie name; But that's gone.

I read other posts that said to try SignInScheme and AuthenticationScheme - and I did, but that would start giving me an error that there was No Provider to Handle this Scheme.

Is there anything I can do for it?

Here's how you can replace the default name used for the external cookie.

services.AddIdentity<Member, Role>(options =>
{
    options.Cookies.ExternalCookie.CookieName = "name";
});
