Worked on enhancing the firebase/quickstart-js repository by implementing a user interface improvement focused on multi-factor authentication. Added a Quick Access Link for SMS-based MFA directly to the main authentication page, aiming to streamline the enrollment process and reduce friction for users during login and verification. This feature was developed using HTML and front end development skills, ensuring a low-risk, targeted update that improved the discoverability and usability of MFA options. The work addressed a specific user flow challenge, making it easier for users to access and set up SMS-based authentication without navigating away from the primary authentication interface.
