How To Make Secure Login Page In Mvc

As a developer, one of the most important aspects of building a web application is ensuring the security of user data. In this article, I will guide you through the process of creating a secure login page in ASP.NET MVC, while adding personal touches and commentary along the way.


Building a secure login page is crucial for protecting user credentials and preventing unauthorized access to your application. ASP.NET MVC provides several built-in features and best practices that you can leverage to create a robust and secure login page.

Step 1: Implementing User Authentication

The first step in creating a secure login page is to implement user authentication. ASP.NET MVC provides the Identity system, which offers a flexible and secure way to manage user authentication and authorization.

To get started, you’ll need to install the required packages via NuGet. Open the NuGet Package Manager Console and run the following command:

Install-Package Microsoft.AspNetCore.Identity

Once the packages are installed, you’ll need to configure the application to use the Identity system. Open the Startup.cs file and add the following code to the ConfigureServices method:

services.AddIdentity<IdentityUser, IdentityRole>().AddEntityFrameworkStores<YourDbContext>().AddDefaultUI().AddDefaultTokenProviders();

Replace YourDbContext with the name of your application’s DbContext class.

Next, you’ll need to update the database schema to include the necessary tables for user authentication. Open the NuGet Package Manager Console and run the following command:


This command will apply any pending migrations and create the required tables in the database.

Step 2: Creating the Login Page

Now that the user authentication system is set up, you can proceed to create the login page. In ASP.NET MVC, views are used to define the user interface. Create a new view called Login.cshtml in the Views/Account folder.

Add the following code to the Login.cshtml file:

ViewData["Title"] = "Login";


This code defines a simple login form with email and password fields. The form posts to the Login action of the AccountController.

Step 3: Implementing Login Functionality

With the login page created, you now need to implement the logic for handling user login. Open the AccountController.cs file and add the following code:

public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = null)
if (ModelState.IsValid)
var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: false);
if (result.Succeeded)
// Redirect to the homepage or the return URL
if (!string.IsNullOrEmpty(returnUrl) && Url.IsLocalUrl(returnUrl))
return Redirect(returnUrl);
return RedirectToAction("Index", "Home");
ModelState.AddModelError(string.Empty, "Invalid login attempt.");

// If we reach this point, there was an error with the form submission
return View(model);

This code handles the post request from the login form. It uses the SignInManager to authenticate the user by their email and password. If the login attempt is successful, the user is redirected to the homepage or the return URL. Otherwise, an error message is displayed.


In this article, we explored how to create a secure login page in ASP.NET MVC. We leveraged the Identity system for user authentication, created a login page with a simple form, and implemented the logic for handling user login.

By following these steps and best practices, you can ensure that your login page is secure and protected against unauthorized access. Remember to always validate user input, use strong and unique passwords, and keep your application and dependencies up to date to mitigate any potential security vulnerabilities.
