Summary
Locks are effectively the primary defense against unauthorized access to smartphones. However, unauthorized access\nby non-strangers seems to be a common occurrence, suggesting that locks often do not fulfill their purpose. To understand the effectiveness of locks, we examine how nonstrangers enact intrusions, even when locks are set up. We\nqualitatively analyzed stories of successful intrusions, recounted by participants in an online study (n = 102). We\nprovide empirical evidence that non-strangers benefit from\nthree inter-dependent factors, that should be taken into account when considering lock effectiveness: trust dynamics,\nphysical proximity, and knowledge of target.\n
