Cybersecurity anxiety captures the persistent worry, stress and perceived lack of control individuals experience when navigating digital threats. While prior research has examined privacy concerns, computer anxiety and related constructs, no validated instrument exists to specifically measure anxiety in cybersecurity contexts. We address this gap with the Cybersecurity Anxiety Scale (CybAS), a 15-item psychometric instrument developed through literature review, item generation, and multiple survey studies. CybAS consists of three factors: Present (current concerns), Future (anticipated threats), and Control (perceived control over outcomes). Analyses confirm strong reliability and validity, and the concise format makes CybAS suitable for both research and applied settings. Beyond measurement, CybAS offers HCI researchers a diagnostic framework for detecting misalignments between users’ mental models and security technologies, enabling the design of anxiety-aware security systems that directly address emotional barriers, bridging the gap between usability, trust, and security.

Account sharing is a common, if officially unsanctioned, practice among workgroups, but so far understudied in higher education. We interview 23 workgroup members about their account sharing practices at a U.S. university. Our study is the first to explicitly compare IT and non-IT observations of account sharing as a "normal and easy" workgroup practice, as well as to compare student practices with those of full-time employees. We contrast our results with those in prior works and offer recommendations for security design and for IT messaging. Our findings that account sharing is perceived as low risk by our participants and that security is seen as secondary to other priorities offer insights into the gap between technical affordances and social needs in an academic workplace such as this.?

Despite slow adoption in the US, mobile payments are thede facto solution for hundreds of millions of users in China for everything from paying bills to riding buses, from sending virtual "Red Packets'' to buying money-market funds. In this paper, we use the theoretical lens of infrastructure to study users' interactions with ubiquitous mobile payment systems in China, focusing on Alipay and WeChat Pay, the two dominant apps on the market. Based on data from a survey (n=466) and follow-up interviews (n=12) with users in China, we describe the diverse usage patterns across physical, social, and digital ubiquity, and a series of challenges people face. Reflecting on the lessons we learned from the Chinese case -- in particular, problems and pitfalls -- we discuss some implications both for design and for policy. Our findings have important implications for other countries that have been moving towards greater adoption of mobile payments.

Work is being digitized across all sectors, and digital account sharing has become common in the workplace. In this paper, we conduct a qualitative and quantitative study of digital account sharing practices in the workplace. Across two surveys, we examine the sharing process at work, probing what accounts people share, how and why they share those accounts, and identifying the major challenges people face in sharing accounts. Our results demonstrate that account sharing in the modern workplace serves as a norm rather than a simple workaround; centralizing collaborative activity and reducing boundary management effort are key motivations for sharing. But people still struggle with a lack of activity accountability and awareness, conflicts over simultaneous access, difficulties controlling access, and collaborative password use. Our work provides insights into the current difficulties people face in workplace collaboration with online account sharing, as a result of inappropriate designs that still assume a single-user model for accounts. We highlight opportunities for CSCW and HCI researchers and designers to better support sharing by multiple people in a more usable and secure way.
