Abstract [en]

In this paper we present a replication and extension of the study performed by Flor^encio and Herley published at SOUPS 2010. They investigated a sample of US websites, examining di erent website features' e ects on the strength of the website's password composition policy (PCP). Using the same methodology as in the original study, we re-investigated the same US websites to identify di erences over time. We then extended the initial study by investigating a corresponding sample of German websites in order to identify di erences across countries. Our ndings indicate that while the website features mostly retain their predicting power for the US sample, only one feature a ecting PCP strength translates to the German sample: whether users can choose among multiple alternative websites providing the same service. Moreover, German websites generally use weaker PCPs and, in particular, PCPs of German banking websites stand out for having generally low strength PCPs.
