A user authentication tool continuously authenticates the user of a computing device during an electronic communication session. A trusted user profile includes keypad pressure applied by the trusted user when depressing characters on a virtual keypad displayed on the computing device touch screen. Keypad pressure applied by the current user of the computing device is continually monitored during the current electronic communication session. The monitored keypad pressure applied by the current user is compared to the keypad pressure in the trusted user profile. A confidence score is generated based upon the compared keypad pressures of the current user and the trusted user, the confidence score being indicative of the likelihood that the current user is the trusted user of the computing device. The computing device is automatically required to re-authenticate the current user as the trusted user if the generated confidence score is below a predefined minimum confidence threshold.
