Month 2025-08 — Security and authentication improvements in the shopware/shopware repo focused on a robust, cloud-friendly login experience and policy-driven access controls. Delivered a new Single Sign-On (SSO) integration for the Shopware admin panel, decoupling authentication from the SBP backend and improving reliability of cloud logins. Implemented enforcement so SSO becomes the sole login method when the default login is disabled, tightening access controls and refining the SSO flow. Fixed a security-related gap by disallowing password grant logins when default login is disabled, closing a potential bypass path and aligning with the new SSO policy.
