F-Secure KEY is a password manager designed to help people securely store and use passwords, PIN codes and account credentials across devices.
My role covered UX and visual design for the mobile product. The central challenge was to make a security-sensitive tool feel clear and approachable without weakening the sense of trust. The experience needed to support strong-password creation, fast credential retrieval and a simple mental model centred on one master password.
I translated the product requirements into focused user flows, understandable interface states and a visual language that made everyday password management feel less technical. The work contributed to improved product usability and, according to my career records, a 30% ROI increase after launch.
