Standard Metrics and Scenarios for Usable Authentication
There is a constant flow of new authentication schemes proposed in the literature. In the past, most proposed schemes were not evaluated empirically, though in recent years there has been an increase in the number of authentication systems that have undergone a user study. Still, most of these user studies employ ad-hoc metrics (e.g., task completion time) and a unique scenario. Bonneau et al. included usability criteria in their heuristic evaluation of various types of web authentication mechanisms.…
