The revamped Windows Hello user experience with new Windows Hello and PINs iconography on the login screen and redesigned Windows security credential user experiences for PIN and passkey (previously impelemented in builds 26257 and 27749 and can be activated manually by enabling the 42941381 velocity staging key)
