密码管理器 (PM) 被认为是提高安全性的高效工具，Pearman 等人最近的一项研究表明。 (SOUPS'19) 强调了采用 PM 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，该方案和访谈工具应用于严格的老年人（> 60 岁）样本，因为之前的工作主要集中在年轻群体中。我们对 PM 用户、内置浏览器/操作系统 PM 用户和非 PM 用户进行了 n=26 次半结构化访谈。参与者的平均年龄为 70.4 岁。使用 Pearman 等人的相同密码本，我们展示了样本之间采用 PM 的差异和相似之处，包括对单点故障的担忧以及控制个人私人信息的重要性。与此同时，老年人对密码云存储和跨设备同步的不信任程度更高。我们还强调了老年人收养 PM 的动机，包括家庭成员推荐的力量以及教育和宣传对提高熟悉度的重要性。
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.
