I want to set up my own login system

But i can not seem to find the Web.config file that i saw on older tutorials

were i can pace the

perhapsit has been removed in the newer version.

follow this, if you have startup.cs instead of web.config

// In the Startup.cs, configure method.
app.UseCookieAuthentication(options =>
{
options.AutomaticAuthenticate = true;
options.AutomaticChallenge = true;
options.LoginPath = "/Home/Login";
});
// Add Authorize attribute to protect the resources you want to secure.
[Authorize]
public IActionResult Index()
{
return View();
}
// In the Home Controller, Login Post action method, write the following method.
var username = Configuration["username"];
var password = Configuration["password"];
if (authUser.Username == username && authUser.Password == password)
{
var identity = new ClaimsIdentity(claims,
CookieAuthenticationDefaults.AuthenticationScheme);
HttpContext.Authentication.SignInAsync(
CookieAuthenticationDefaults.AuthenticationScheme,
new ClaimsPrincipal(identity));
return Redirect("~/Home/Index");
}
else
{
ModelState.AddModelError("","Login failed. Please check Username and/or password");
}
