FIDO2 the Rescue? Platform vs. Roaming Authentication on Smartphones. (arXiv:2302.07777v1 [cs.CR])

Modern smartphones support FIDO2 passwordless authentication using either
external security keys or internal biometric authentication, but it is unclear
whether users appreciate and accept these new forms of web authentication for
their own accounts. We present the first lab study (N=87) comparing platform
and roaming authentication on smartphones, determining the practical strengths
and weaknesses of FIDO2 as perceived by users in a mobile scenario. Most
participants were willing to adopt passwordless authentication during our
in-person user study, but closer analysis …
