讲座摘要:

Because humans have limited memory and cognitive capacity, Internet users tend to adopt redundant, easy-to-remember passwords for their online accounts. Paradoxically, mobile password manager apps are widely available that can help users automatically generate, store, and retrieve their passwords; but many users resist using them in deference to continuing with their weak password habits. In this study, drawing upon theories of habit breaking and habit formation, we designed a set of interventions in a mobile password manager app to promote the use of complex, random, and unique passwords for users’ online accounts. With a self-developed password manager app, UXApp, we conducted a longitudinal field experiment to test the effectiveness of our proposed habit-breaking and habit-formation intervention designs. 910 password selection behaviors were observed from 91 unique users of UXApp. The results indicate that both just-in-time warning (as a habit-breaking feature) and visualized performance dashboard (as a habit-formation feature) can significantly improve users’ password management practices. In addition, just-in-time warning has an immediate treatment effect, which is relatively stable over time; in contrast, visualized performance dashboard has a non-immediate, accumulative treatment effect over time. We enrich the current password management research by investigating the longitudinal effects of habit-breaking and habit-formation interventions, and thus contribute to practice by improving Internet users’ password management practices.
