Create the Home Controller

using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using System.Security.Claims;

namespace App_Auth_Authorization.Controllers
{
    public class HomeController : Controller
    {
        public IActionResult Index()
        {
            return View();
        }

        [Authorize]
        public IActionResult Employee()
        {
            return View();
        }
 public async Task<IActionResult> Authenticate()
        {
            var Auth_Claims = new List<Claim>
            {
                new Claim(ClaimTypes.Name,"labpys.com"),
                new Claim(ClaimTypes.Name,"Example@labpys.com"),               

            };

            var license = new List<Claim>() {

                new Claim(ClaimTypes.Name, "Admin"),
                new Claim("UniqueIdentity", "B+"),

            };


            var AuthIdenity = new ClaimsIdentity(Auth_Claims, "Auth_Tutorial");
            var LicenseIdentity = new ClaimsIdentity(license, "Auth_Tutorial");
            var userPrincipal = new ClaimsPrincipal( new[] { AuthIdenity, LicenseIdentity });
            await HttpContext.SignInAsync(userPrincipal);

            return Redirect(nameof(Index));
        }

        
    }
}

Authorization – To make ASP.NET Core Authorized Attribute work, you must include the relevant middleware in program class.

var builder = WebApplication.CreateBuilder(args);

var services = builder.Services;    

services.AddControllersWithViews();

services.AddAuthentication("CookieAuth")
    .AddCookie("CookieAuth", config =>
    {
        config.Cookie.Name = "Auth_Tutorial";
        config.LoginPath = "/Home/Authenticate";

    });
services.AddMvc();

var app = builder.Build();

app.UseAuthentication();
app.UseRouting();
app.UseAuthorization();


app.UseEndpoints(endpoints =>
{
    endpoints.MapDefaultControllerRoute();
});
app.Run();

Customize View
