启动后启用/禁用身份验证选项

Question

我想创建一个自定义 CMS，其中管理员可以在其管理面板中选择所有可能的登录选项。但我只能在我的 Startup.cs 中为 OWIN 设置第三方登录：

public partial class Startup
{
    public void ConfigureAuth(IAppBuilder app)
    {
        // Enable the application to use a cookie to store information for the signed in user
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login")
        });
        // Use a cookie to temporarily store information about a user logging in with a third party login provider
        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

        // Uncomment the following lines to enable logging in with third party login providers
        app.UseMicrosoftAccountAuthentication(
            clientId: "00000000000000000",
            clientSecret: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");

        app.UseTwitterAuthentication(
            consumerKey: "xxxxxxxxxxxxxxxxxxxxxx",
            consumerSecret: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");

        app.UseFacebookAuthentication(
            appId: "000000000000000",
            appSecret: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");

        app.UseGoogleAuthentication();
    }
}

我想从我正在运行的应用程序中启用和禁用这些登录选项。这样启动后。这可能吗？如果可以，怎么做？

大多数登录流程是由用户从列表中选择一个身份验证提供程序触发的。您可以只显示/隐藏该列表中的项目。
