Abstract
A client system comprises processing circuitry configured to receive, from an authorisation system, a first grant token for identifying the client system at the authorisation system, the first grant token having a corresponding time to expire indicative of a time at which the first grant token will not be valid for obtaining a protected resource from a resource system. The client system transmits, to the authorisation system, a refresh request for a second grant token for identifying the client system at the authorisation system, wherein the refresh request is transmitted based on the expiry time of the first grant token; and receives the second grant token at the client system, in response to the refresh request.
