The BankID IDP in the OIDC Provider is a multi-tennant service having the capability to host several BankID merchant certificates. In its default configuration all OIDC Clients share a common BankID merchant certificate associated with the BankID OIDC Service itself. Alterntively, an OIDC Client may be configured with its own BankID merchant certificate. The BankID IDP supports each of the BankID B2C Services (netcentric and mobile).

There are several benefits for merchants integrating BankID over OIDC rather than using a legacy integration via a locally installed BankID-server:

• The integration interface is the same for each of the BankID B2C Services  (netcentric and mobile).
• The merchant does not need to implement any GUI for BankID on mobile since it is taken care of by the OIDC Provider itself
• The merchant does not need to implement a selector dialog for netcentric vs. mobil since the OIDC Provider offers such a selector dialogue.
• The integration interface is based on an industry-standard REST API being much more convenient than implementing via the legacy BankID-server.
• The merchant may have access to Supplementary Services that are not available via the legacy BankID server.

An OpenID Client make use of BankID either via login hints directly in the REST API or via integration with the BankID Connector.
