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

It's quite common to show user profile data on the UI after they have authenticated. Let's see how we can do this in our Blazor Server application.

# Authentication and user profile

Before going into the code, let’s understand what happens when the user authenticates with Auth0.

After the authentication, Auth0 generates a token in **JSON Web Token** (**JWT**) format. This token, known as the **ID token**, contains some information about the authentication operation and some data about the user, such as their name and picture. Our Blazor Server application receives the ID token from Auth0 when the user is redirected back to it.

To access the user profile, we need to access the ID token and extract that data. Luckily, the Auth0 AS<span>P.NET</span> Core Authentication SDK get this data for us right after the authentication process.
