Abstract
A method and apparatus for authorizing a user is provided. A requestor submits a request for challenge data to a device. The device generates the challenge data and provides the challenge data to the requestor. The requestor obtains response data that is responsive to the challenge data. The requestor may obtain the response data by providing, to a third party, the challenge data and identification information for the requestor. Upon the third party successfully validating the identity of the requestor, the third party provides the response data to the requestor. The requestor thereafter submits the response data to the device. In response to receiving the response data from the requestor, the device verifies the response data. Upon the device successfully verifying the response data, the device grants access to the requestor.
