We conduct research on human-centered IT Security. This entails the design of security technologies that are easy to use, inclusive, and privacy-friendly. Our vision is that people should be able to live a secure digital life without having deep technical knowledge. Towards this end, we conduct research on a variety of topics, including password security and usability, behavioral implicit authentication, behavioral data privacy, privacy awareness, and transparency enhancing technologies.
