May 2025 monthly summary for the developer team. Key features delivered and major improvements across two repositories: - IPV JWKS-based key retrieval integration and tests (auth API): Implemented environment-aware JWKS-based retrieval of IPV public encryption key, refactored IPVReverificationService for testability, added required egress/infrastructure changes to enable external calls, and expanded integration tests to improve end-to-end coverage. - Commons-validator upgrade (auth API): Upgraded commons-validator from 1.8.0 to 1.9.0 to keep dependencies current and reduce risk. - Frontend authentication flows (auth frontend): Added new authentication app and test coverage for how the security codes flow, plus implemented howDoYouWantSecurityCodesPost for SMS users including MFA handling. Refactors and test improvements across the security codes flow. - MFA and security codes enhancements: Propagated defaultMfaMethodId and MFA method IDs to the backend, enhanced resend flow and template data handling (including redacted phone numbers), and centralized MFA error handling to improve reliability. - Code quality, maintenance and platform alignment: Removed deprecated supportAccountRecovery usage across authentication flow, app init, requests, and tests; cleaned up test imports; adopted a GenericApp channel across MFA/security-code flows and renamed components to reflect new app grouping; added uplift template option for trying another method. - Test infrastructure and reliability: Multiple test improvements and cleanup, including reset password email tests and fixes to test imports to ensure tests run reliably.

April 2025 monthly summary: Delivered security and governance improvements for MFA management, enhanced account-management API with templates and docs, and expanded testing capabilities across acceptance and smoke tests. Key features delivered include MFA method management with principal validation and Redis Parameter Store access (AUT-4199, AUT-4134), MFA method templates and documentation (BAU commit), and test infrastructure improvements for readability and consistency. Additionally, migrated test user lifecycle support in acceptance tests (AUT-4202) and upgraded smoke-test environments to Node.js 20 and Puppeteer 10 to align with modern runtimes.
