User Perceptions of the Usability and Security of Smartphones as FIDO2 Roaming
summary
A 97-participant between-subjects study tests a smartphone-based FIDO2 roaming prototype called Neo prototype against traditional passwords for a fictitious bank over two weeks. Key findings: over half dropped out during setup, passwords are faster and yield higher task success and SUS scores, yet all Neo users rate security higher. Main barriers are phone availability, battery and connectivity, and account recovery/backup complexity, which explain why security gains do not translate into better usability.
