SignInStatus always returns Success on TwoFactorAu

问题:

I am implementing 2 factor authentication in WebApi, asp.net identity and OWIN. Every time I log in, I get SignInStatus = Success never reaches to SignInStatus = RequiresVerification though user TwoFactorAuthentication is enabled.

Below are some code snippets, Startup.cs:

private void ConfigureAuth(IAppBuilder app)
        {
            app.UseCookieAuthentication(new CookieAuthenticationOptions());
            app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
            app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));
            app.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);

            app.UseOAuthBearerTokens(OAuthOptions);
        }


Action method for enabling two factor authentication,
[HttpPost]
        public async Task<IHttpActionResult> EnableTwoFactorAuthentication()
        {
            var user = await this.AppUserManager.FindByIdAsync(User.Identity.GetUserId());
            if (user != null)
            {
                IdentityResult result = await this.AppUserManager.SetTwoFactorEnabledAsync(User.Identity.GetUserId(), true);

                await this.AppSignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);

                if (!result.Succeeded)
                {
                    return GetErrorResult(result);
                }
            }
            return Ok();
        }

Please suggest a solution.

If you get stuck here, one way to solve the problem is to copy the methods from SignInManager directly into your code and call those instead so you can step through the methods and see why you are getting the wrong status. For me the problem ended up being that I instantiated my UserManager with:

new MyUserManager() 

instead of the right way:

HttpContext.GetOwinContext().Get<MyUserManager>()

I was using this as my template for setting it up: https://github.com/adamtuliper/ASP.NET-Identity-Samples/tree/master/BasicTemplate%20-%20Two%20Factor/BasicTemplate
