Biometric authentication offers promise for mobile security, but its adoption can be controversial, both from a usability and security perspective. We describe a preliminary study, comparing recollections of biometric adoption by computer security experts and non-experts collected in semi-structured interviews. Initial decisions and thought processes around biometric adoption were recalled, as well as changes in those views over time. These findings should serve to better inform security education across differing levels of technical experience. Preliminary findings indicate that both user groups were influenced by similar sources of information; however, expert users differed in having more professional requirements affecting choices (e.g., BYOD). Furthermore, experts often added biometric authentication methods opportunistically during device updates, despite describing higher security concern and caution. Non-experts struggled with the setting up fingerprint biometrics, leading to poor adoption. Further interviews are still being conducted.
