A Minimum ID Token returned by the OIDC Provider from BankID contains a minimum set of standardized claims marked by (tick) and (warning), among which sub is the only claim that is linked to the actual user. Claims marked by (warning) are currently not supported but will be added. A minimum ID Token can be used by OIDC Clients that need to authenticate end-users in an anonumous way. The sub value does not identify the user unless it is linked by the OIDC Client to other claims about the end user associated with that sub value.

An Enlarged ID Token adds some basic (and standardized) claims about the end user to the ID Token, depending on the scopes and claims actually requested by the OIDC Client. Additional claims about the authenticated user beyond this basic set is available via Userinfo associated with the Additional Information service. The basic claims from the enlarged ID Token are duplicated in the reponse from Userinfo. Note that the basic claims of the enlarged ID Token are returned without requesting an explicit consent from the end-user. This is in contrast to additional claims available via Userinfo that as a rule-of-thumb demand explicit consent from the user.
