Blazor Authentication? Hold My Beer!

Talkat NDC London 2026 · 2026-01-26..01-30· [security, web-platform]
slides:none on file

Explains concrete recipes for cookie + OpenID Connect in Blazor Server, WebAssembly and Auto (hybrid): use authorization code flow with a server-side token store, proactive refresh via Duende.AccessTokenManagement, and a BFF (back end for front end) that issues same-site strict session cookies. Shows code hooks: implement token store interface, register Duende.BFF and map BFF endpoints, or proxy external APIs with YARP and an access token HTTP client. Demos login, claims and API calls working end-to-end.
