April 2026: Delivered end-to-end TOTP MFA support in the Admin Console for edificeio/entcore, enabling admins to enroll and manage TOTP secrets with UI updates, backend validation, and unit tests. Implemented validation schema changes, session state improvements to expose TOTP status, and UI enhancements on the user detail and OTP authentication pages. Added translations and logging for MFA analysis, set the TOTP generator to 60 seconds, and implemented checks to prevent secret key reuse across users. These changes strengthen security, improve enterprise readiness, and come with robust test coverage and maintainability.

February 2026 monthly summary for edificeio/entcore focusing on delivering a robust mobile authentication flow and improving token-based access. Key deliverable: a Mobile App Pre-authentication Token API that enables mobile clients to retrieve a pre-authentication token from the Carbonio service. Implemented the API endpoint via GET cabonion/token with strengthened error handling and clear failure paths to improve reliability and user experience. The work reduces mobile login friction while enhancing security posture through token-based access. Commit referenced: 9d489e9c3e2b253f7f2bcb8ff007cea755f5140c.

January 2026 monthly summary for edificeio/entcore. Key feature delivered: Federated Authentication Flag by Login Method. Implemented gating logic to set a federated status only when the user selects a qualifying login method, enhancing authentication security and user experience. This work included aligning the auth flow with security expectations and documenting behavior for future audits. Major bug fix: corrected federated flag assignment to ensure status is set only for valid login method choices, per INTEG-1028. Overall impact: stronger security posture, reduced risk of incorrect federation states, and smoother user authentication flow. Contributes to compliance and reliability of the authentication subsystem. Technologies/skills demonstrated: authentication flow design, conditional logic and guard clauses, feature flag/flagging patterns, commit-based traceability, security-conscious coding, and collaboration through issue tagging (INTEG-1028).
