A digital license includes an identification of a removal service that can authorize removing such license. A client selects the license to be removed and the service, constructs a challenge including therein a challenge license identification block (LIB) identifying the license to be removed, and sends the challenge to the service. The service receives the challenge, stores at least a portion of the challenge in a database, constructs a response corresponding to the challenge and including therein a response LIB identifying the license to be removed and an identification of the service, and sends the response to the client. The client receives the response, employs the response LIB from the response to identify the license to be removed, and removes the identified license upon confirming that the identification of the service in the identified license matches the identification of the service in the response.

Creating an account via a mobile device. A request to create an account is received from a user via a mobile device. The request is received from the mobile device according to a wireless communications protocol. In response to the received request, a confirmation message is delivered to the mobile device for rendering to the user as a challenge. A response to the rendered challenge is received from the user via the mobile device. It is determined if the received response to the rendered challenge corresponds to the delivered confirmation message. And the account is created for the user if the received response to the rendered challenge is determined to correspond to the delivered confirmation message. Other aspects of the invention are directed to computer-readable media for use with account creation via a mobile device.
