Dissecting Nudges in Password Managers: Simple Defaults are Powerful
summary
Large online study (n=853) simulates Safari’s UI on Chrome via a user‑agent header and six conditions on Mechanical Turk to measure randomly generated password (RGP) adoption. Main claim: Safari’s higher RGP rate traces to a simple autofill default that prepopulates RGPs; visual highlight (yellow faded field) increases noticeability but not adoption; popup message and a crafted social nudge show no boost. Results raise ethics concerns about unnoticed defaults and informed consent.
