Abstract: Methods, systems, computer-readable media, and apparatuses for interactive challenges for accessing a resource are presented. In some embodiments, a method may include presenting a challenge requesting the performance of a specific motion. The method may also include capturing sensor data generated by one or more sensors associated with a mobile device as a result of one or more actions performed by a user in response to the challenge. The method may additionally include determining whether the specific motion was performed by comparing the captured sensor data to reference data associated with the requested specific motion. The method may further include indicating whether the challenge was satisfied based at least in part on the determining.
