I 'read an article on CNN this AM about a new privacy feature planned for iOS. It will require faceID or fingerprintID to change things like faceID and fingerprintID. While this does make things more secure what happens if those biometrics fail. I help people my age with their phones with my weekly tech help group. Many of these seniors have problem using faceID or fingerprintID. I have helped some users set their fingerprints only to have them return two weeks later with them not working anymore. They usually ask to turn the feature off.
