ASP.Net Identity provider requests too much information

My indentity asp.net is working fine. However, when the user logs in, Google asks the user if he will be okay to provide the following information:

- View your email address
- View basic information about your account

The problem is that I do not even want this information. I just want a unique way to identify the user (which he provides). I do not want users to think that I am going to spam them at the entrance.

In Startup.Auth.cs, I use google's very vanilla setting:

app.UseGoogleAuthentication();

EDIT: SOLUTION

Brock's answer led me to the right decision. The key thing was to add "openid" to the scope.

    var googleOAuth2AuthenticationOptions = new GoogleOAuth2AuthenticationOptions
        {
            ClientId = "XXXX",
            ClientSecret = "YYYY",
            CallbackPath = new PathString("/Account/LoginCallback/"),
        };

    googleOAuth2AuthenticationOptions.Scope.Add("openid"); //!Important

    app.UseGoogleAuthentication(googleOAuth2AuthenticationOptions);
