In August 2025, Jouni Leinonen updated the CSCfi/csc-user-guide repository to clarify and enforce Multi-Factor Authentication (MFA) requirements for user accounts. He focused on improving the documentation by explicitly stating the MFA policy, reducing ambiguity for both users and support teams. Using Markdown and leveraging his documentation skills, Jouni delivered a single, auditable change set that aligns the user guide with current security standards. This update not only enhances the clarity of onboarding and account management processes but also supports future audits and updates. The work addressed a targeted need without introducing new features or bug fixes beyond documentation.
