How do I pick an authentication type in a new asp net core 7 project

Introduction

When a new ASP.NET Core 7 project, one of the important decisions you need to make is choosing the authentication type. The authentication type determines how users will be authenticated and authorized in your application. In this article, we will explore different authentication available in ASP.NET Core 7 and provide examples to help you pick the one for your project.

Forms Authentication

Forms authentication is a widely used authentication type in ASP.NET applications. It allows users to authenticate using a username and password combination. To enable forms authentication in your ASP.NET Core 7 project, you can use the following code:


.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(options =>
    {
        options.LoginPath = "/Account/Login";
        options.LogoutPath = "/Account/Logout";
    });

In the above example, we configure the authentication middleware to use the authentication . We also the login and logout paths for the authentication process.

OAuth Authentication

OAuth authentication is commonly used when you want to allow users to authenticate using their existing social media accounts, such as Google, Facebook, or Twitter. To enable OAuth authentication in your ASP.NET Core 7 project, you can use the following code:


services.AddAuthentication()
    .AddGoogle(options =>
    {
        options.ClientId = "YOUR_GOOGLE_CLIENT_ID";
        options.ClientSecret = "YOUR_GOOGLE_CLIENT_SECRET";
    })
    .AddFacebook(options =>
    {
        options.AppId = "YOUR_FACEBOOK_APP_ID";
        options.AppSecret = "YOUR_FACEBOOK_APP_SECRET";
    });

In the above example, we configure the authentication middleware to use Google and Facebook as external authentication . We provide the necessary client ID and client secret for each provider.

Identity Authentication

Identity authentication is a comprehensive authentication system provided by ASP.NET Core. It allows you to user accounts, roles, and permissions within your application. To enable identity authentication in your ASP.NET Core 7 project, you can use the following code:

In the above example, we configure the authentication middleware to use the Identity framework with the default IdentityUser and IdentityRole classes. We also specify the Entity Framework as the data store for user and role management.

Conclusion

Choosing the right authentication type is crucial for the security and functionality of your ASP.NET Core 7 project. In this article, we explored three authentication types: forms authentication, OAuth authentication, and identity authentication. Depending on your project requirements, you can choose the appropriate authentication type and configure it accordingly. Remember to secure sensitive information and follow best practices when implementing authentication in your application.
