A security method and system. The method includes retrieving configuration data associated with a non interactive entity (NIE) software application. The configuration data comprises refresh counts, refresh periods, and session IDs. A master refresh period is calculated from the refresh periods. Credentials data associated with a requestor are retrieved. The credentials data are transmitted to a resource server. A session key generated by the resource server is received by the NIE software application. The NIE software application calculates a stale time associated with the session key. The NIE software application generates a first updated refresh count. The NIE software application stores the session key, the first updated refresh count, the first refresh period, and the first specified stale time.
