How to correctly implement authentication in Blazor depends on the mode your using it in. Blazor Server requires an approach that is totally different than when using Blazor WebAssembly. And if you use a mix of the two rendering modes things can get very complicated.

This session is here to help you out. We'll cover the right way to do cookie and OpenID Connect authentication for both modes as well as the mix mode.

At the end of the session you'll be able to confidently secure any Blazor application.

You will learn:

  • Understand that the right way to protect Blazor applications depends on how you use it
  • How to apply OAuth/OpenID Connect using the various Blazor "modes"
  • Untangle the confusing information on the web about Blazor auth
