Another .NET 10 passkeys post! The server's origin is used to generate passkey credentials. A credential signed for one app can't be used elsewhere.

The upcoming release of #dotnet 10 comes with built-in passkey support. Had good fun digging into the new #Blazor project template and how it adds secure authentication using passkeys.
