Mobile authentication is a crucial component of authentication more broadly, especially as mobile devices become evermore connected to the broader computer security ecosystem. The overarching goal of my research is to improve the current state of mobile authentication by taking a holistic approach to measuring mobile authentication and its impacts that intersect directly with the user experience. In this talk, I will present a narrative of contributions to mobile authentication over the last 10 years, focusing on how human factors impact the security, from attacks, choices, and perceptions. I will particularly focus on one form of mobile authentication, Android's graphical pattern unlock, which may be the most heavily used graphical authentication system, ever. Based on my experience, I will also present some new directions and methods that can improve the security of mobile authentication and some new results on PINs and LG's graphical Knock Code Authentication.
