Computer systems and methods are provided for performing authentication of a user. A computer system receives, from a camera on an electronic device distinct from the computing system: a single captured image that includes a first facial image of a user and an image of a document that includes a second facial image of the user, and a third facial image of the user captured at a different time from the first facial image. The computer system determines whether the first facial image and the second facial image meet matching criteria. The computer system determines, using the third facial image, that the user is moving. And, in accordance with determinations that the first facial image and the second facial image meet the matching criteria and that the user is moving, the computer system transmits authorization information for the user to the electronic device.
