Dec 1, 2025December 2025 monthly highlights for zitadel/zitadel: Key features delivered, major bugs fixed, overall impact, and technical proficiency demonstrated. 1) Key features delivered: Implemented Client Credentials Token Lifetime from Server Defaults by adding a new ID token lifetime field to the client_credentials client structure and defaulting it to the server's configured lifetime, improving token management security and usability. 2) Major bugs fixed: Resolved an issue where ID tokens could be issued without a defined lifetime in the client_credentials flow (commit 1ce8bcbd781573606c1d3f13162ff490a5b9c02f; references #11060). 3) Overall impact and accomplishments: Token lifetimes now align with centralized server policies, reducing misconfigurations and security risk across service-to-service integrations; improved predictability and maintainability of token issuance. 4) Technologies/skills demonstrated: Go and server-config driven defaults, security token management, codebase familiarity with zitadel/zitadel, and contributions that enhance policy compliance and system robustness.
