Or try `<%= Context.User.Identity.IsAuthenticated %>` – Jo Smo May 04 '15 at 22:45

Nothing new to add to Griegs answer, but I would normally do

@Request.IsAuthenticated

Looking at the reference sources for `HttpRequestWrapper` and then `HttpRequest` the `IsAuthenticated` property is implemented with `User.Identity.IsAuthenticated`, among other things. `return(_context.User != null && _context.User.Identity != null && _context.User.Identity.IsAuthenticated);` – ta.speot.is Jul 07 '13 at 08:18

So what's the difference? Or are these two identical? – Jo Smo Jan 09 '16 at 16:06
Pretty much. Mine is shorter. :-) – Dan Atkinson Jan 10 '16 at 00:07

As the original question did not have access to `User`, how would this make any difference "in a user control". Your example is in a controller and not a user-control. -1 – iCollect.it Ltd Jul 24 '15 at 11:40
