You can use ViewModel and than you can just use DataAnnotations here is how Controller, ViewModel and View looks in that case (translation is Croatian).

Controller

    [HttpGet]
    public IActionResult Login()
    {
        return View();
    }

    [HttpPost]
    public async Task Login(LoginViewModel model)
    {
        if (ModelState.IsValid)
        {
            var result = await signInManager.PasswordSignInAsync(
                model.Email, model.Password, model.RememberMe, false);

            if (result.Succeeded)
            {
                return RedirectToAction("index", "home");
            }

            ModelState.AddModelError(string.Empty, "Neuspješni pokušaj");
        }

        return View(model);
    }

ViewModel

Under ErrorMessage put your error message

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Threading.Tasks;

namespace MyApplication.ViewModels
{
    public class LoginViewModel
    {
        [Required(ErrorMessage = "Email je obavezan")]
        [EmailAddress]
        public string Email { get; set; }

        [DataType(DataType.Password)]
        [Display(Name = "Lozinka")]
        [Required(ErrorMessage = "Lozinka je obavezna")]
        public string Password { get; set; }

        [Display(Name = "Zapamti me")]
        public bool RememberMe { get; set; }
    }
}

Login View

@model LoginViewModel

@{
    ViewBag.Title = "Prijava";
}

Prijava


    

        

            

            

                
                
                
            
            

                
                
                
            
            

                

                    
                        
                        @Html.DisplayNameFor(m => m.RememberMe)
                    
                
            
            Prijava
