1. A method, comprising: capturing, by a computing device, an image including at least a face of a user; calculating, by the computing device, a face template of the face of the user in the image; analyzing, by the computing device, the face template to determine whether the face includes at least one of a removable facial feature that decreases a level of distinctiveness between two faces and a non-removable facial feature that decreases a level of distinctiveness between two faces; responsive to determining that the face includes the removable facial feature, outputting, by the computing device, a notification to request that the user remove the removable facial feature; and responsive to determining that the face includes the non-removable facial feature, adjusting, by the computing device, a first similarity score threshold to a second similarity score threshold.
