Worked on the elizaOS/eliza repository to enhance CLI login reliability and security by addressing both feature development and bug resolution. Delivered a new CLI login keys lifecycle feature that enforces a single active key per user, deactivates legacy keys, and supports key rotation and rollback, thereby improving session management and security best practices. Resolved a deadlock in the CLI login UI by refining React useEffect dependencies and implementing a guard to prevent duplicate session completion requests. Leveraged JavaScript, React, and cloud authentication technologies to streamline API key generation workflows and ensure robust, efficient authentication processes for end users.
