A method comprising: receiving, by at least one processor of a computing device, data indicative of a plurality of images of a face of a known user; determining, by the at least one processor, a number of pose buckets of a plurality of pose buckets that include the plurality of images of the face of the known user, wherein each of the one or more images of the face of the known user is included in at least one pose bucket from a plurality of pose buckets , and each pose bucket from the plurality of pose buckets is associated with a respective range of pitch angles of the face of the known user and a respective range of yaw angles of the face of the known user; determining, by the at least one processor, whether the number of pose buckets satisfies a threshold number of pose buckets; responsive to determining that the number of pose buckets satisfies a threshold number of pose buckets, associating, by the at least one processor, the data indicative of the plurality of images with a user account for the known user; receiving, by the at least one processor of the computing device, data indicative of an image of a face of an unknown user of the computing device while the computing device is in a reduced access mode; determining, by the at least one processor, whether the unknown user is a known user of the computing device by at least comparing the data indicative of the image of the face of the unknown user to data indicative of one or more images of a plurality of images of a face of the known user; and, responsive to determining that the unknown user is the known user, setting, by the at least one processor, the computing device to an increased access mode, wherein the increased access mode is associated with the user account for the known user. receiving, by at least one processor of a computing device, data indicative of a plurality of images of a face of a known user; determining, by the at least one processor, a number of pose buckets of a plurality of pose buckets that include the plurality of images of the face of the known user, wherein each of the one or more images of the face of the known user is included in at least one pose bucket from a plurality of pose buckets , and each pose bucket from the plurality of pose buckets is associated with a respective range of pitch angles of the face of the known user and a respective range of yaw angles of the face of the known user; each of the one or more images of the face of the known user is included in at least one pose bucket from a plurality of pose buckets , and each pose bucket from the plurality of pose buckets is associated with a respective range of pitch angles of the face of the known user and a respective range of yaw angles of the face of the known user; determining, by the at least one processor, whether the number of pose buckets satisfies a threshold number of pose buckets; responsive to determining that the number of pose buckets satisfies a threshold number of pose buckets, associating, by the at least one processor, the data indicative of the plurality of images with a user account for the known user; receiving, by the at least one processor of the computing device, data indicative of an image of a face of an unknown user of the computing device while the computing device is in a reduced access mode; determining, by the at least one processor, whether the unknown user is a known user of the computing device by at least comparing the data indicative of the image of the face of the unknown user to data indicative of one or more images of a plurality of images of a face of the known user; and, responsive to determining that the unknown user is the known user, setting, by the at least one processor, the computing device to an increased access mode, wherein the increased access mode is associated with the user account for the known user. <EOS>
