Worked on the VirtoCommerce/vc-platform repository to update authentication branding in alignment with Microsoft Entra ID. Focused on configuration management, the developer modified the appsettings.json file to replace references to Azure Active Directory with Microsoft Entra ID, ensuring consistency with current branding standards. This change was implemented exclusively through JSON configuration, with careful validation to avoid any functional regressions or disruptions to authentication workflows. The update supported broader adoption of Entra ID by clarifying identity surfaces for users. No bugs were addressed during this period, and the work centered on non-functional, config-only improvements to maintain brand clarity and technical accuracy.
