Developed and delivered WebAuthn Origin Policy Enforcement for the keycloak/keycloak repository, focusing on enhancing authentication security and configurability. Implemented server-side validation of WebAuthn credentials in Java, ensuring that authentications are accepted only from the base origin and any policy-defined extra origins. This approach introduced policy-driven allowlisting, allowing enterprises to tailor origin policies for WebAuthn registrations and improve compliance. The work demonstrated expertise in backend development and WebAuthn protocol handling, with all changes traceable through version control. No major bugs were addressed during this period, as the primary focus remained on feature delivery and strengthening authentication policy enforcement.
