This is happening because you are using same layout in Login.cshtml.
To resolve this issue try this: 1. Create at location Shared --> _AnonymousLayout.cshtml >    html   lang = "en" >    head >         meta   charset = "utf-8"   />         meta   name = "viewport"   content = "width=device-width, initial-scale=1.0"   />         title > @ViewData["Title"] - WebApplication2 title >         link   rel = "stylesheet"   href = "~/lib/bootstrap/dist/css/bootstrap.min.css"   />         link   rel = "stylesheet"   href = "~/css/site.css"   />    head >    body >         header >             nav   class = "navbar navbar-expand-sm navbar-toggleable-sm navbar-light bg-white border-bottom box-shadow mb-3" >                 div   class = "container" >                     a   class = "navbar-brand"   asp-area = ""   asp-controller = "Home"   asp-action = "Index" > WebApplication2 a >                     button   class = "navbar-toggler"   type = "button"   data-toggle = "collapse"   data-target = ".navbar-collapse"   aria-controls = "navbarSupportedContent"                             aria-expanded = "false"   aria-label = "Toggle navigation" >                         span   class = "navbar-toggler-icon" > span >                     button >                     div   class = "navbar-collapse collapse d-sm-inline-flex justify-content-between" >                         ul   class = "navbar-nav flex-grow-1" >                             li   class = "nav-item" >                                 a   class = "nav-link text-dark"   asp-area = ""   asp-controller = "Home"   asp-action = "Index" > Home a >                             li >                             li   class = "nav-item" >                                 a   class = "nav-link text-dark"   asp-area = ""   asp-controller = "Home"   asp-action = "Privacy" > Privacy a >                             li >                         ul >                     div >                 div >             nav >         header >         div   class = "container" >             main   role = "main"   class = "pb-3" >                @RenderBody()            main >         div >            footer   class = "border-top footer text-muted" >             div   class = "container" >                © 2021 - WebApplication2 -  a   asp-area = ""   asp-controller = "Home"   asp-action = "Privacy" > Privacy a >             div >         footer >         script   src = "~/lib/jquery/dist/jquery.min.js" > script >         script   src = "~/lib/bootstrap/dist/js/bootstrap.bundle.min.js" > script >         script   src = "~/js/site.js"   asp-append-version = "true" > script >        @await RenderSectionAsync("Scripts", required: false)   body >    html >    2. Add this in the beginning of Login.cshtml file:
@{       Layout =  "_AnonymousLayout" ;   }

Hi Sachin      Out of the below 2 only 1 is to be used in Route.Config   routes.MapRoute( name: "LoginStart", url: "", defaults: new { controller = "Home", action = "Login" } );
routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); }   Thanks

You don't need to change anything just make sure you have two different layouts one for login and one for other actions and everything will work fine.

Try this   @{        if  (!User.Identity.IsAuthenticated)       {           Context.Response.Redirect(Url.Action( "Login" ,  "Home" , new  { ReturnUrl = Context.Request.Path }));       }   }

Hi varun     I am getting error -  This Page is not working http://localhost:6784/Home/Login      In Main Layout i have written  @{ if (!User.Identity.IsAuthenticated) { Context.Response.Redirect(Url.Action("Login", "Home")); } } *****************************       Below is my login Page. @Html.Partial("~/Views/Shared/_Login.cshtml") $(function () { $("#myModal").modal('show'); })   ******* Below is the Home Controller public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpGet] public ActionResult Login(string ReturnUrl) { ViewBag.ReturnUrl = ReturnUrl; //return View(); return View(); }   ****************8 Route.Config public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); }

Sachin Singh · Answer

simply set the Login page as the startup page, for the rest of the application your Authorization module will work as expected.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "LoginStart",
url: "",
defaults: new { controller = "Home", action = "Login" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}

Add this code at the beginning of layout    @{        if  (!User.Identity.IsAuthenticated)       {           Context.Response.Redirect(Url.Action( "Login" ,  "Home" ));       }   }

Hi Varun     I have different Layout for Login & Main Layout. I want before Main Layout opens it should be checked whether user is authenticated or not. If not then LOgin Page should open.   Thanks

Varun Setia · Answer

This worked for me.
Note: Do not use same layout for Login   @{        if  (!User.Identity.IsAuthenticated)       {           Context.Response.Redirect(Url.Action( "Login" ,  "Home" ));  // Login Page         }   }
