May 2026 – auth0/docs-v2 progress: Delivered two major features focused on secure, scalable integrations and delegated authorization, while maintaining a strong security posture through updated docs. Key features: M2M support for third-party apps via client_credentials grant; Custom Token Exchange (CTE) with delegated authorization and actor delegation enhancements. These workstreams included updates to security controls and API/docs (e.g., get-token flows). Commits 537231f4186bad9a6354cf5ae9b6acead724438b, 560fedae1203af1d6a808cbd9551b5ff8353da69, and c0a7e0943421b02891e7855ddadb4b0a350f0e8a reflect code and documentation changes with cross-team reviews and co-authors. No major production bug fixes were recorded this month; focus remained on feature delivery, QA, and documentation improvements. Business impact: enables secure automation and integrations for third-party apps, tightens authorization controls, clarifies act claims and MFA restrictions, and accelerates developer onboarding and time-to-value for integrations with our platform.

Month: 2026-04 — Auth0/docs-v2 delivered metadata-driven dynamic URLs for Third-Party Initiated Login by documenting and enabling metadata placeholders in the application-level initiate_login_uri. This enables dynamic login_uri construction using organization and custom domain metadata, reducing manual configuration, improving tenant branding, and strengthening governance over login flows. Key updates included: (1) documented supported placeholders, fallback behavior, and the restriction that tenant-level default_redirection_uri does not support placeholders; (2) expanded docs to include Organization and Custom Domain placeholders, security warnings, and KEY format clarifications; (3) updated related documentation pages (wildcards-for-subdomains) and added cross-reference from the MCD page; (4) codified placeholder support in the Application Login URI fields in docs. Impact: Improves deployment scalability for multi-tenant setups, accelerates onboarding of new orgs, and reduces manual error in login URL configuration. Security notes help mitigate potential metadata exposure in URLs. No major bug fixes were reported for this repository in this period. Collaboration: Co-authored updates with team members to ensure consistency across docs.
