Worked on the slaclab/sdf-docs repository to clarify documentation around MFA SSH key validity, focusing on improving the user authentication experience. The update involved removing references to key expiration, thereby simplifying the explanation of what constitutes a 'valid' key for SSH logins using multi-factor authentication. This documentation change, implemented in Markdown, aimed to align the written guidance with actual security best practices and the current MFA SSH login workflow. By refining the language and structure of the documentation, the work reduced onboarding friction for new users and helped decrease support queries related to authentication, demonstrating attention to both usability and security.
