Get AuthenticationProperties in current HttpRequest after HttpContext.SignInAsync

Question

I'm using ASP.net Core MVC. In the login process, in a POST controller action, I am using HttpContext.SignInAsync with an AuthenticationProperties that contains a JWT access token. In the same HttpRequest, I cannot refetch those properties to get the access token that was created.

...
var claimsPrincipal = CreateClaimsPrincipal("userName");

var accessToken = new AuthenticationToken()
{
    Name = OpenIdConnectParameterNames.AccessToken,
    Value = TOKEN_VALUE
};
AuthenticationToken[] tokens = { accessToken };

var authenticationProperties = new AuthenticationProperties();
authenticationProperties.StoreTokens(tokens);
authenticationProperties.IsPersistent = true;

// Here we sign in the user
await HttpContext.SignInAsync(claimsPrincipal, authenticationProperties);

// Afterwards, we cannot access the access token either from
var tokenValueFromGetTokenAsync = HttpContext.GetTokenAsync(OpenIdConnectParameterNames.AccessToken)
// Or with
var result = await HttpContext.AuthenticateAsync();
var tokenValueFromAuthenticateAsync = result.Properties.GetTokenValue(OpenIdConnectParameterNames.AccessToken);

Is there a way to set the AuthenticationProperties of the current http request ? I know I can set the ClaimsPrincipal with

HttpContext.user = claimsPrincipal

But is there something similar that I can do with AuthenticationProperties. Something like

// I made that part up, would be cool though
HttpContext.Authentication.Properties = authenticationProperties

I uploaded a super simple code example of this to github:

GitHub code example

check the SecurityController Login method decorated with a HttpPost attribute.

There is a much cleaner way to do this...

var authFeatures = context.Features.Get<IAuthenticateResultFeature>();
var authProps = authFeatures.AuthenticateResult.Properties;

This provides direct access to the AuthenticationProperties decrypted from the ticket by the authentication middleware.

For AuthenticationProperties, try to save it by options.Events.OnSignedIn like

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(options =>
    {
        options.LoginPath = new PathString("/Security/Login");
        options.Events.OnSignedIn = context => {
            var httpContext = context.HttpContext;
            httpContext.Items["Properties"] = context.Properties;
            httpContext.Features.Set(context.Properties);
            return Task.CompletedTask;
        };
    });

And then retrieve by

public async Task<IActionResult> Login(LoginModel model)
{
    if (ModelState.IsValid)
    {
        var claimsPrincipal = CreateClaimsPrincipal(model.Name);
        var authenticationProperties = CreateAuthenticationProperties();

        await HttpContext.SignInAsync(claimsPrincipal, authenticationProperties);

        HttpContext.User = claimsPrincipal;

        var properties1 = HttpContext.Features.Get<AuthenticationProperties>();
        var properties2 = HttpContext.Items["Properties"];           

        return RedirectToAction(nameof(HomeController.Index), nameof(HomeController));
    }
    else
    {
        return View(model);
    }
}

Another option, you may consider adding a new method which is used to retrieve the properties like:

    public async Task<IActionResult> Login(LoginModel model)
    {
        if (ModelState.IsValid)
        {
            var claimsPrincipal = CreateClaimsPrincipal(model.Name);
            var authenticationProperties = CreateAuthenticationProperties();

            await HttpContext.SignInAsync(claimsPrincipal, authenticationProperties);

            return RedirectToAction(nameof(CheckProperties));
        }
        else
        {
            return View(model);
        }
    }

    public async Task<IActionResult> CheckProperties()
    {
        await FetchTokenAndVerify();
        return RedirectToAction(nameof(HomeController.Index), nameof(HomeController));
    }
