Using Single Sign-On for Securing Applications in ASP.NET Core

Securing web applications is extremely important, as you do not want unauthorized people to gain access to your data. The most convenient way of securing an application is to use single sign-on (SSO) because it allows users to authenticate once and gain access to all apps within the same system.

In this course, you’ll cover the process of using SSO in ASP.NET Core apps. You’ll also cover its usage inside all application types supported by ASP.NET Core, including MVC, web API, gRPC services, Blazor, and SignalR.

By the end of this course, you will have learned what SSO consists of, what protocols it uses, and how it’s configured inside an ASP.NET Core middleware. You will also have learned how to secure any endpoints, pages, and views supported by ASP.NET Core.
