US Patent 9871791 Multi factor user authentication on multiple devices

Systems and methods of the present invention provide for a first and second client computer configured to receive and transmit an authentication credential and at least one additional authentication credential respectively. The authentication credentials may be selected from authentication credentials known only to a user, identifying a client computer and/or identifying a characteristic unique to the user. A server computer communicatively coupled to the network may be configured to receive the authentication credentials and verify the identity of the user via a match, in a database, of a first authentication credential, a second authentication credential and a third authentication credential.
