Kat Krol

I am a user experience researcher in the Pico project, which, under the leadership of Frank Stajano, aims to liberate humanity from passwords.

I am passionate about conducting user studies in security and privacy. My past research has looked at the user experience of various authentication mechanisms, warnings, webforms and messaging apps.

Before joining the Pico Team, I was based in the Information Security Research Group at University College London where I also did my PhD under the supervision of Angela Sasse.
