A hardware security key for user authentication on computing devices is described. The security key is responsive to a user touch pattern and includes a set of conductive plates. Based on matching the entered pattern to a preset pattern, the security key transmits a secret to the computing device that enables the user to be authenticated. The pattern can include specific areas of the conductive plates that are touched in a particular sequence and/or a touch dwell time associated with the user touch. An LED can be provided on the security key to provide an indication to the user of a successful or unsuccessful authentication attempt.
