US Patent 11695758 Second factor authentication of electronic devices

A method for a multi-factor authentication, the method receives results of an initial authentication of a user. Responsive to confirming the initial authentication, an image of a secondary set of authentication options is presented. An option selection is received from the user, wherein the selection is determined by tracking eye movement of the user over the image that includes the set of second factor authentication options. User facial activity is tracked corresponding to the selection made from the secondary set of authentication options. The monitored facial activity is compared to a pre-established authentication condition to determine whether a match exists with the selected secondary set of authentication options, and responsive to facial activity monitored matching the authentication condition pre-established by the user and corresponding to the selection made from the secondary set of authentication options, authentication of the user is confirmed.
