Blazor is a .NET framework that delivers native performance on web clients through C# runtimes and HTML wrapping. Auth0 helps you secure these applications through identity management, authentication, and authorization.

This course is a step-by-step guide to securing Blazor Server and Blazor WebAssembly applications with Auth0. You’ll start with an introduction to Blazor and its two hosting models— server-side and portable WASM binarie. You’ll then explore Auth0, which is an identity and access management (IAM) platform for connected applications. Next, you’ll set up and run a server application, integrate the Auth0 SDK, and add login functions before testing for security. You’ll finish by creating a Blazor WASM application and protecting each individual component with Auth0, including the UI and the Web API.

By the end of this course, you’ll be equipped with the proper tools to build and deploy secure web applications with the .NET’s Blazor framework and secure them with Auth0.

Securing Blazor Applications with Auth0

The Blazor WebAssembly application seems to be protected from unauthorized access. While the user needs to be authenticated to access its pages, the API providing the weather forecast data is not protected. Let's see how we can check this.

# The ASP.NET Core API

The Blazor WebAssembly application has been created as an ASP.NET Core hosted application. This means that the WebAssembly code of the application is served by an ASP.NET Core web application.

In addition, this ASP.NET application implements a web API that provides the weather forecast data.
We can check this architecture in the server project's code:

Learn to check if the API called by the Blazor WebAssembly application is protected.
