In this post I look at the passkey support added to ASP.NET Core Identity and the Blazor Web App template, explore how it works, and look at the implementation

Andrew Lock's blog focuses on ASP.NET Core development, web APIs, and software architecture. Readers can find tutorials, code samples, and explanations covering topics such as RESTful API design, authentication, and authorization in ASP.NET Core. Additionally, they can learn about dependency injection, middleware, and performance optimization techniques.

.NET Escapades

ASP.NET Core Identity in .NET 10 preview 6 introduces passkey support as an alternative authentication method. The implementation allows users to register passkeys after creating password-based accounts, enabling biometric or PIN-based login through WebAuthn standards. The feature includes new Blazor components, JavaScript integration for browser WebAuthn APIs, and database schema changes to store passkey credentials. While providing enhanced security over passwords, the current template still requires initial password registration, limiting the full passwordless potential of passkeys.
