# Creating a Custom Login and Signup System with Bootstrap in .NET Core.

#### Introduction

In this day and age, it's super important to have a secure and easy-to-use login/signup system for your web application. And.NET Core is a great framework for doing just that - it's cross-platform and super fast, so you don't have to worry about it. In this guide, we'll show you how to make a custom login/signup system with .NET Core. Plus, we'll give you some tips on how to make it look and feel better with Bootstrap - a popular UI framework for making responsive and eye-catching web interfaces.

#### Requirements

Before continuing with the tutorial, make sure you have the following requirements are met:

1. **Install the .NET Core SDK on your development computer.**
2. **Install a code editor like Visual Studio Code or Visual Studio.**
3. **Must have the basic knowledge of C# and ASP.NET Core.**

## Step 1: Create a New .NET Core Project

Setting up a new [.NET Core project](https://www.mindstick.com/category/article/asp-dot-net-core) started, open a terminal or **command prompt** and run the following commands:

```cs
dotnet new web -n CustomLoginSignup
cd CustomLoginSignup
```

This will create a new .NET Core web application named **"CustomLoginSignup."**

## Step 2: Install Bootstrap

To use Bootstrap's functionality in the front end, you need to include [Bootstrap in your project](https://www.mindstick.com/articles/1665/creating-and-activating-tabs-with-bootstrap). To do this, you can either download the Bootstrap CSS and JavaScript files manually or use a package manager like npm or Bower. For simplicity, we embed Bootstrap into our project using a [Content Delivery Network](https://www.mindstick.com/interview/33679/what-is-content-delivery-network) (CDN).

If you include Bootstrap in your theme, be sure to add these lines to the **_Layout.chtml** file inside your Views/Shared folder:

## Html Code

```cs
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
```

## Step 3: Create Login and Signup Views

Let's now begin the creation of the login view and signup view. Create two new folders in the **'Views'** folder, named **'Account'** and **'Views',** respectively. These folders will contain two Razor views, **'Login' and 'Signup'.** These Razor views will include the HTML structure of the login form and the [signup](https://www.mindstick.com/articles/12557/login-and-registration-in-asp-dot-net-mvc) form respectively.

## Step 4: Create Login and Signup Controllers

Now, configure your controller to control login and signup requests. Run the following command in the terminal:

```cs
dotnet add package Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation
dotnet add package Microsoft.AspNetCore.Identity.EntityFrameworkCore
dotnet add package Microsoft.EntityFrameworkCore.SqlServer
dotnet add package Microsoft.EntityFrameworkCore.Tools
```

Create two controllers, **‘LoginController’** and **‘SignupController’**, to manage user [authentication](https://www.mindstick.com/articles/75394/implement-authentication-using-identity-model-in-asp-dot-net-core) and signup respectively. Implement the required actions and logic.

## Step 5: Configure Identity

You can manage [user authentication](https://www.mindstick.com/forum/159936/what-are-oauth-and-openid-connect-and-how-do-they-simplify-user-authentication) using [ASP.NET Core Identity](https://www.mindstick.com/articles/75394/implement-authentication-using-identity-model-in-asp-dot-net-core). To configure identity, paste the following code into the ConfigureServices.cs file:

```cs
 services.AddIdentity<IdentityUser, IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders();
```

Also, don't forget to configure the necessary middleware and services for authentication in the `Configure` method of the same file.

## Step 6: Create a Database Context

A [database context](https://www.mindstick.com/articles/324875/update-dbcontext-from-database-using-entity-framework-core-in-asp-dot-net-mvc-core) is required to save user data to the database. To define the database context for [your application](https://answers.mindstick.com/qa/97584/how-do-you-choose-the-correct-camera-for-your-application), create an inheritable class called DbContext and add it to your **startup.cs** file using the ConfigureServices method.

## Step 7: Implement Login and Signup Logic

**LoginController and SignupController** use Identity to implement login and signup operations. Ensure user input is validated, passwords are encrypted, and user data is stored securely.

#### Conclusion

This tutorial has provided a step-by-step guide on how to develop a.NET Core-based login and signup solution, as well as how to enhance the front end using Bootstrap. Establishing a reliable authentication system is essential for the development of secure and intuitive [web applications](https://www.mindstick.com/blog/11464/improve-your-understanding-of-web-applications). By adhering to these steps and tailoring them to the specific needs of your project, you can ensure a smooth login and signup process for your users.
