To achive this I had use cookies.The approch I follow is below
Create a BaseController Class and inherit all your controller with this BaseController.
In your BaseController ,Override onActionExecuting Method like below

C#

public class BaseController : Controller
   {

       protected override void OnActionExecuting(ActionExecutingContext filterContext)
       {
           string value =cookie //assign you cookie value.

           base.OnActionExecuting(filterContext);
           string controllerName = filterContext.Controller.GetType().Name;
           string actionName = filterContext.ActionDescriptor.ActionName;
           if (string.IsNullOrEmpty(value))
           {
               if (!controllerName.Equals(typeof(LoginController).Name))
                   filterContext.Result = new RedirectToRouteResult(
                       new RouteValueDictionary {
                       { "Controller", "Login" },
                       { "Action", "Index" }
                       });
           }
           else
           {
               if (string.IsNullOrEmpty(Session["UserId"])
               {
                  //code to re-initilize your session from cookies
               }
              
           }
       }
