A method, comprising: at an electronic device with one or more biometric sensors and a display: displaying, on the display, a biometric enrollment user interface for enrolling a biometric feature, wherein displaying the biometric enrollment user interface includes displaying a representation of the biometric feature, wherein the appearance of the representation of the biometric feature changes as the orientation of the biometric feature relative to the one or more biometric sensors changes, and wherein the biometric feature includes biometric data associated with a portion of a face; while displaying the biometric enrollment user interface: enrolling a portion of the biometric feature; and after enrolling the portion of the biometric feature, detecting that enrollment-prompt criteria have been met with respect to one or more portions of the biometric feature; and in response to detecting that the enrollment-prompt criteria have been met with respect to one or more portions of the biometric feature, outputting a respective prompt to move the biometric feature in a respective manner, wherein the respective prompt is selected based on an enrollment state of one or more portions of the biometric feature and is displayed over the representation of the biometric feature, including: in accordance with a determination that the enrollment-prompt criteria have been met with respect to a first portion of the biometric feature that can be enrolled by moving the biometric feature in a first manner, outputting the respective prompt includes outputting a visual prompt including an element that provides an indication to move the biometric feature in the first manner; and in accordance with a determination that the enrollment-prompt criteria have been met with respect to a second portion of the biometric feature, different from the first portion of the biometric feature, that can be enrolled by moving the biometric feature in a second manner, different from the first manner, outputting the respective prompt includes outputting a visual prompt including an element that provides an indication to move the biometric feature in the second manner. displaying, on the display, a biometric enrollment user interface for enrolling a biometric feature, wherein displaying the biometric enrollment user interface includes displaying a representation of the biometric feature, wherein the appearance of the representation of the biometric feature changes as the orientation of the biometric feature relative to the one or more biometric sensors changes, and wherein the biometric feature includes biometric data associated with a portion of a face; while displaying the biometric enrollment user interface: enrolling a portion of the biometric feature; and after enrolling the portion of the biometric feature, detecting that enrollment-prompt criteria have been met with respect to one or more portions of the biometric feature; and enrolling a portion of the biometric feature; and after enrolling the portion of the biometric feature, detecting that enrollment-prompt criteria have been met with respect to one or more portions of the biometric feature; and in response to detecting that the enrollment-prompt criteria have been met with respect to one or more portions of the biometric feature, outputting a respective prompt to move the biometric feature in a respective manner, wherein the respective prompt is selected based on an enrollment state of one or more portions of the biometric feature and is displayed over the representation of the biometric feature, including: in accordance with a determination that the enrollment-prompt criteria have been met with respect to a first portion of the biometric feature that can be enrolled by moving the biometric feature in a first manner, outputting the respective prompt includes outputting a visual prompt including an element that provides an indication to move the biometric feature in the first manner; and in accordance with a determination that the enrollment-prompt criteria have been met with respect to a second portion of the biometric feature, different from the first portion of the biometric feature, that can be enrolled by moving the biometric feature in a second manner, different from the first manner, outputting the respective prompt includes outputting a visual prompt including an element that provides an indication to move the biometric feature in the second manner. in accordance with a determination that the enrollment-prompt criteria have been met with respect to a first portion of the biometric feature that can be enrolled by moving the biometric feature in a first manner, outputting the respective prompt includes outputting a visual prompt including an element that provides an indication to move the biometric feature in the first manner; and in accordance with a determination that the enrollment-prompt criteria have been met with respect to a second portion of the biometric feature, different from the first portion of the biometric feature, that can be enrolled by moving the biometric feature in a second manner, different from the first manner, outputting the respective prompt includes outputting a visual prompt including an element that provides an indication to move the biometric feature in the second manner.
