    abstract = {Authentication (e.g., entering a password) is frequently perceived as an annoying obstacle when interacting with computational devices, but still essential to protect sensitive data from unauthorized access. We present Act2Auth, a novel concept for embedding authentication into users’ established routines by sensing tangible interactions at desks. With Act2Auth, users can authenticate by performing (secret) routines, such as putting a cup on their desk, rearranging their keyboard, and touching their mouse. The Act2Auth concept is informed by (1) an object analysis of 107 desk photos from Reddit, (2) an online survey (N = 65) investigating users’ strategies for creating touch-based authentication secrets, and (3) a technical exploration of capacitive touch-sensing at desks. We then (4) implemented a prototype and evaluated the usability as well as the memorability of Act2Auth compared to textual passwords (N = 8). With Act2Auth, we provide fundamental work on how to embed authentication tasks into our daily tangible interactions.},
