论文摘要
密码管理器（PMS）被认为是提高安全性的高效工具，以及Pearman等人的最新研究。 （汤3）强调了采用PMS的动机和障碍。我们通过复制Pearman等人的方案和访谈工具来扩展这些发现，该方案和访谈工具适用于严格的老年人样本（> 60岁），因为先前的工作集中在一个主要年轻的队列上。我们对PM用户，内置浏览器/操作系统PM用户和非PM用户进行N = 26个半结构化访谈。平均参与者年龄为70.4岁。使用Pearman等人的同一代码手册，我们展示了样本之间PM采用的差异和相似之处，包括担心单个失败点以及控制一个人的私人信息的重要性。同时，发现老年人对密码云存储和跨设备同步的不信任感更高。我们还重点介绍了老年人的PM采用动机，包括家庭成员的推荐能力以及教育和推广的重要性，以提高熟悉程度。
Password managers (PMs) are considered highly effective tools for increasing security, and a recent study by Pearman et al. (SOUPS'19) highlighted the motivations and barriers to adopting PMs. We expand these findings by replicating Pearman et al.'s protocol and interview instrument applied to a sample of strictly older adults (>60 years of age), as the prior work focused on a predominantly younger cohort. We conducted n=26 semi-structured interviews with PM users, built-in browser/operating system PM users, and non-PM users. The average participant age was 70.4 years. Using the same codebook from Pearman et al., we showcase differences and similarities in PM adoption between the samples, including fears of a single point of failure and the importance of having control over one's private information. Meanwhile, older adults were found to have higher mistrust of cloud storage of passwords and cross-device synchronization. We also highlight PM adoption motivators for older adults, including the power of recommendations from family members and the importance of education and outreach to improve familiarity.
