Abstract: While previous work on smartphone (un)locking has revealed real world usage patterns, several aspects still need to be explored. In this paper, we fill one of these knowledge gaps: the interplay between age and smartphone authentication behavior. To do this, we performed a two-month long field study (N = 134). Our results indicate that there are indeed significant differences across age. For instance, younger participants were more likely to use biometric un- locking mechanisms and older participants relied more on auto locks.
