Abstract
Physical security methods and equipment are applied to mobile devices that use multi-factor authentication mobile apps. Herein, a password management mobile app physically escrows each encrypted password that must be stored into two parts. These are then distributed between two separate, independent physical devices. Only one of those parts is kept only in a separate user gadget like a keyfob. Any reconstitution of each password after decryption requires that the user have on-hand both the mobile device and the separate user gadget. Such reconstitution is one password at a time, and only as needed, and released for use in remote authentication with a master user password entry.
