This disclosure describes techniques to reduce the risk of a data breach when a mobile device is stolen. In certain modes, e.g., augmented reality (AR) mode, selfie mode, etc., optimal use of a mobile device requires that the user hold the device out at an arm’s length in a public location, leading to an increased likelihood of theft. With user permission, a potential risk state is activated upon detecting such use of the device. If sudden movement of the device, e.g., as detected by an on-board accelerometer, location sensor, or other sensor is detected, the device is automatically locked, requiring user authentication for data access. If the user permits, location tracking is also activated which can assist physical recovery of the device.
