Any tutorials on how to add authentication to an existing BLAZOR .NET 8 project?

[GlacierFox]

I've got an existing Blazor Web App (Interactive Server Render) I've built that I want to add authentication to. Can anyone point me to some step-by-step resources to start me off? I can't seem to find anything with detailed and clear instruction.

I'm not thinking the best approach might be to simply create a fresh Blazor project front the command line with authentication and the Blazor Identity UI and attempt to duplicate it into my current project?

Thanks
