A method of accessing a service includes receiving, from a requesting user, a request for a number of accessing users to have access to the service; generating service access data associated with the service; providing, to the requesting user, the generated service access data for distribution to the accessing users; receiving service access data from an accessing user; determining, based in part on the received service access data, whether the service can be provided; and where it is so determined, providing the service to the accessing user.
