Oct 1, 2025

Month: 2025-10. Focused on delivering robust authentication key management and stabilizing QA automation. Implemented dynamic JWT Key ID management across selfcare microservices by replacing hardcoded KIDs with a dynamic RSA_KEYS_IDENTIFIERS reference, enabling flexible key rotation and consistent behavior across development and QA environments in selfcare-client-users-updater and selfcare-onboarding-consumer. Fixed QA workflow timeout reference bug to correct timeout comparisons, reducing flaky tests and improving automation reliability.
