The xID IDP in the OIDC Provider provides access to the xID Service at LoA2. An integral part of the xID IDP is to provide stepup to the BankID IDP whenever required. Note that such stepup is initated, and handled, by the xID IDP itself when the end-user cannot be determined via device detection. The merchant is not involved in any way for such a stepup. This is in contrast to any stepup from xID to BankID that the merchant may initiate for other business reasons. In the later case the OIDC Client for the merchant needs to be registered and configured both for the xID service and the BankID service.
Note that values for
id_token_hint request parameter.
An OIDC Client may also customize its use of the xID IDP.
