Scopes and claims beyond those asociated with ID Tokens are used to request Access Tokens (with corresponding Refresh Tokens) of the right kind for subsequent access to various resources at supported Resource Servers. See the description of specific scopes and claims for each supported Value-added Service (VAS). The TINFO service is of particular importance since it implements the standard scopes address, phone and email as defined by the OpenID Connect specification itself.
The scope named offline_accesaccess is a standard scope with implication on session handling. See also the description on Refresh Token for further information on the effect of this particular scope.
