The more accounts I use, the less I have to think': A Longitudinal Study on the...
summary
Longitudinal study of n=37 novices uses a 3‑month commercial password manager with weekly surveys (weeks 1–4) and a week‑12 follow up, finding initial usability decides adoption: perceived usability stays flat while trust rises and dropouts come from low SUS scores. Key numbers: 44% reuse a primary password, only 14% record the recovery kit, stored logins rise from 5 to 6 on average, 79% show weak or reused credentials in audit screenshots, and ignored credential audit flags undermine security. Recommendations: guided setup, just‑in‑time settings links, video help, and gamified nudges.
