Developed and delivered OAuth 2.0 Device Code Flow Authentication for the anaconda-auth repository, enabling secure device-based login where user authorization occurs on a separate device. This feature addressed usability and security challenges for headless or limited-input environments by implementing the device code grant flow and integrating it with conda APIs. The work involved backend development in Python, API development, and enhancements to the terminal user experience. Additional efforts included updating dependencies, aligning tests with conda_api, and refactoring code for maintainability by fixing documentation paths and removing deprecated references, resulting in a more robust and user-friendly authentication process.
