This publication describes techniques for combining detected motion with multiple facial images for biometric authentication on an electronic device. The motion is detected by one or more motion sensors on the electronic device. The motion may be indicative of a gesture made by the user of the electronic device, for example, a twist of the device in the user’s hand. Motion information is analyzed to determine a user’s intent to access the device. Responsive to determining a user’s intent to access the device, multiple images of the user’s face are captured by a front-facing RGB camera to build a composite image of the person who is attempting to access the device. The images are analyzed, along with the motion information, to provide biometric authentication for the device.
