Systems and Methods for Authenticating Users of a Computer System

An authentication system for allowing access to a user account server has at least one access device and at least one verification server. The at least one access device is capable of operatively connecting to the user account server and comprises a touch screen for allowing entry of session signatures. The at least one verification server is capable of comparing session signatures to reference signatures. A user reference signature is stored on the at least one verification server. The at least one access device allows entry of a user session signature and transmission of the user session signature to the at least one verification server. The at least one verification server allows the at least one user to connect to the user account server based on a comparison of the user session signature with the user reference signature.
