Abstract
Many users now access password-protected accounts and websites alternately from desktop machines, and mobile devices (e.g., smartphones, tablets). The input mechanisms of the mobile devices are often miniature physical or virtual on-screen keyboards, posing challenges for users trying to type passwords with mixed-case and special-charactersexpected by websites and more easily entered on desktop keyboards. We begin with a review of these challenges and existing proposals addressing cross-device password entry, including some password managers. We then bring the issues into focus with detailed discussion of the interoperation challenges, and implementation details, and interface details of the object-based password “ObPwd ” mechanism, as implemented for the Android platform, plus compatible browser-based and stand-alone implementations for desktop environments. ObPwd generates a password from a user-selected digital object (e.g., image), does not require changes to server-side software, and avoids the text-input challenges of mobile devices. We also briefly evaluate ObPwd using a recently proposed evaluation framework for password authentication schemes. A major goal is to increase attention to the cross-device password authentication problem. 1
