Abstract
A computing device described herein utilizes a secure cryptoprocessor of the computing device to compute a response to a request for authorization received from another local or remote device. The secure cryptoprocessor computes the response based on protected authorization credentials stored by the secure cryptoprocessor for one or more devices. The computing device then provides the computed response to the other device to cause the other device to grant or deny authorization. The computing device may also display information associated with the request for authorization, receive input indicating approval of the request, and utilize the secure cryptoprocessor in response to the received input.
