How to use "User.Identity.IsAuthenticated" in Web API

Question

User.Identity.IsAuthenticated always returns false in my ASP.NET Web API project.

In account ApiController I have following:

ClaimsIdentity identity = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie); 
AuthenticationManager.SignIn(new AuthenticationProperties() { 
    IsPersistent = isPersistent 
}, identity);

After signing in, User.Identity.IsAuthenticated is always false in ApiController but true in MVC Controller.

Answer 1

The ApiController has a User property and is available from:

base.User.Identity.IsAuthenticated
