Worked on enhancing authentication documentation for the MicrosoftDocs/powerquery-docs repository, focusing on the Databricks connector. Updated the documentation to replace legacy Username and Password authentication with a secure OAuth Machine-to-Machine workflow, guiding users through the process of generating Databricks Client Credentials. Emphasized security best practices and provided clear, step-by-step instructions to support enterprise customers migrating to modern authentication methods. Utilized Markdown for technical writing and documentation, ensuring clarity and accessibility. The work improved onboarding and ongoing support by reducing risk and aligning with current security standards, addressing the needs of organizations integrating with Databricks SQL Warehouses.
