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. <br class=""></div><div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class=""><br class=""></div><div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class=""><b class="">Bio:</b><br class=""></div><div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class="">Adam J.
