This is how I got an AspNetUser Id and displayed it on my home page

I placed the following code in my HomeController Index() method

ViewBag.userId = User.Identity.GetUserId();

In the view page just call

ViewBag.userId

Run the project and you will be able to see your userId

Getting the Id is pretty straight forward and you ve solved that   Your second question though is a little more involved   So  this is all prerelease stuff right now  but the common problem you re facing is where you re extending the user with new properties   or an Items collection in you re question    Out of the box you ll get a file called IdentityModel under the Models folder  at the time of writing    In there you have a couple of classes  ApplicationUser and ApplicationDbContext  To add your collection of Items you ll want to modify the ApplicationUser class  just like you would if this were a normal class you were using with Entity Framework   In fact  if you take a quick look under the hood you ll find that all the identity related classes  User  Role etc     are just POCOs now with the appropriate data annotations so they play nice with EF6   Next  you ll need to make some changes to the AccountController constructor so that it knows to use your DbContext   public AccountController         IdentityManager   new AuthenticationIdentityManager      new IdentityStore new ApplicationDbContext          Now getting the whole user object for your logged in user is a little esoteric to be honest        var userWithItems    ApplicationUser await IdentityManager Store Users      FindAsync User Identity GetUserId    CancellationToken None     That line will get the job done and you ll be able to access userWithItems Items like you want   HTH

In  Net MVC5 core 2 2  I use HttpContext User Identity Name   It worked for me

User · Answer

If you re coding in an ASP NET MVC Controller  use  using Microsoft AspNet Identity        User Identity GetUserId      Worth mentioning that User Identity IsAuthenticated and User Identity Name will work without adding the above mentioned using statement  But GetUserId   won t be present without it    If you re in a class other than a Controller  use  HttpContext Current User Identity GetUserId      In the default template of MVC 5  user ID is a GUID stored as a string   No best practice yet  but found some valuable info on extending the user profile    Overview of Identity  https   devblogs microsoft com aspnet introducing-asp-net-identity-a-membership-system-for-asp-net-applications  Example solution regarding how to extend the user profile by adding an extra property  https   github com rustd AspnetIdentitySample

I feel your pain  I m trying to do the same thing  In my case I just want to clear the user   I ve created a base controller class that all my controllers inherit from  In it I override OnAuthentication and set the filterContext HttpContext User to null      That s the best I ve managed to far     public abstract class ApplicationController   Controller                  protected override void OnAuthentication AuthenticationContext filterContext                base OnAuthentication filterContext             if                                  You may find that modifying the                 filterContext HttpContext User                 here works as desired                  In my case I just set it to null             filterContext HttpContext User   null
