Going Passwordless - A Practical Guide to Passkeys in ASP.NET Core
summary
Passkeys replace passwords using WebAuthn public‑key signing and work with OS authenticators, password managers, or USB keys; a Blazor Server demo on .NET 10 shows registration via navigator.credentials.create and login via passkey JSON sent to passkey creation/login endpoints. ASP.NET Identity requires ASP.NET Identity schema version 3 (adds SPNet user passkey storage) and careful relying‑party/origin setup; demo authentication succeeds, with a noted OnePassword JSON stringify interoperability fix.
