Worked on the basecamp/omarchy repository to improve the FIDO2 authentication setup by addressing error handling and user feedback. Focused on preventing silent failures during the authentication process, the update introduced explicit, user-facing messages when errors such as mistyped PINs occurred. This approach enhanced troubleshooting and reduced support workload by guiding users through setup issues. The solution was implemented using shell scripting and system administration skills, emphasizing lightweight, incremental changes for easier review and rollback. By refining error handling in the FIDO2 flow, the work aligned with security best practices and contributed to a more reliable authentication experience for users.
