We are excited to have two papers accepted at ACSAC 2021! First, The Emperor’s New Autofill Framework: A Security Analysis of Autofill on iOS and Android. This paper examines the security of password autofill frameworks built into Android and iOS, finding significant issues with each. Second, Systematization of Password Manager Use Cases and Design Paradigms. This paper systematizes how users leverage password managers and how password managers are implemented to support those use cases. This is a critical paper for anyone looking to design user studies of password managers.
