Abstract
Security credentials issued by an entity, such as an identity broker, can have a limited lifetime. Access to resources or content under those credentials then can only be obtained for a limited period of time, limiting the ability of an unauthorized entity obtaining the credentials to utilize those credentials for access. Along with the credentials, a refresh token can be issued to a requesting client that can enable the limited lifetime of the credentials to be renewed up to a maximum lifetime of the credentials and/or the token. A service providing access can determine that the client has a valid copy of the refresh token when the credentials are about to expire, and if so can cause the lifetime of the credentials to be extended another credential lifetime. This renewal can be done transparent to a user and without again contacting the identity broker.
