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

After registering our Blazor Server application with Auth0 and preparing the configuration settings, it’s time to implement the actual integration.

[OpenID Connect](https://openid.net/connect/) and [OAuth2](https://oauth.net/2/) protocols handle authentication and authorization, which may add complexity to the process. The [Auth0 ASP.NET Core Authentication SDK](https://github.com/auth0/auth0-aspnetcore-authentication) helps hide this underlying complexity.

To install the Auth0 SDK, let's move to the root folder of our project and run the following command in a terminal window:

```
dotnet add package Auth0.AspNetCore.Authentication
```

After a few seconds, the `Auth0.AspNetCore.Authentication` package will be downloaded from NuGet and installed in our Blazor Server project.

Use the Auth0 ASP.NET Core Authentication SDK to let our Blazor Server application interact with the Auth0 platform.
