reuse is more prevalent than previously believed, especially when partial reuse is taken into account; and that password managers may have no impact on password reuse or strength.  ...  Most studies examine one password or a small number of passwords per user, and studies o en rely on passwords created solely for the purpose of the study or on passwords protecting low-value accounts.  ...  reuse, whether users understand the concept of higher-and lower-value accounts, and to what extent password managers improve the strength or usability of passwords.  ...

(How) Do people change their passwords after a breach? [article]

Sruti Bhagavatula, Lujo Bauer, Apu Kapadia
2020 arXiv   pre-print
To study the effectiveness of password-related breach notifications and practices enforced after a breach, we examine---based on real-world password data from 249 participants---whether and how constructively  ...  Of the 249 participants, 63 had accounts on breached domains; only 33% of the 63 changed their passwords and only 13% (of 63) did so within three months of the announcement.  ...  Parts of the dataset we used were created through work supported by the National Security Agency under Award No. H9823018D0008.  ...

Vijay Kothari, Jim Blythe, Sean W. Smith, Ross Koppel
2015 Proceedings of the 2015 Symposium and Bootcamp on the Science of Security - HotSoS '15  
In this paper, we argue in favor of cognitive behavioral agent-based modeling for usable security and report on our work on developing an agent-based model for a password management scenario.  ...  We perform a number of trials and a sensitivity analysis that provide valuable insights into improving security (e.g., an organization that wishes to suppress one form of circumvention may want to endorse  ...  Acknowledgment This material is based in part upon work supported by the Army Research Office under Award No. W911NF-13-1-0086.  ...

Why Do Not We Use Password Managers? A Study on the Intention to Use Password Managers

Ramakrishna Ayyagari, Jaejoo Lim, Olger Hoxha
2020 Contemporary Management Research  
Therefore, understanding the factors that influence the use of a password manager is important. We contribute to this cause by drawing on information security and technology adoption literature.  ...  However, perceived ease of use diminished the intent to use password managers, and trust is only partially supported.  ...  Therefore, we control the impact of perceived usefulness and perceived ease of use in this study on the intention to use password managers by modeling them as control variables.  ...

2018 Journal of Computers  
We also studied the impact of age and domain knowledge on choosing passwords. The analysis shows that complex password polices are annoying for users and it takes more time to create such passwords.  ...  In this study we investigated the usability of password policies and users' perceptions of password security. We conducted a user study based on experimental evaluation and online survey.  ...  Researchers have been actively involved in studying the impact of password meters and password composition policies on security and usability of passwords.  ...
