Identity Providers

Introduction

The following sub-sections contain information on the Identity Provider (IDP) options supportedby this release of the OpenID Connect Provider from BankID. See general information on user experience that applies for the various IDP.

Each IDP option is associated with a Name and Level of Assurance (LoA) codified via attributes called amr (Authentication Method Reference) and acr (Authentication Context Class Reference), respectively. These attributes can be included in the request from an OIDC Client to the authorize endpoint at the BankID OIDC Provider to request either a particular IDP (amr) or any IDP at a particular LoA (acr). A standard and designated request parameter exists for the acr attribute (see authroize for details). As there is no corresponding request parameter for the amr attribute, the BankID OIDC Provider supports amr values codified as part of the login_hint parameter (more on this in the section below).


Successful authentication via one of the supported IDPs results in an ID Token being returned to the requesting OIDC Client. Note that an ID Token also contain values for the amr and acr attributes, corresponding to the IDP actually being used. These values may be different from corresponding values provided in the request from the OIDC Client to the authorize endpoint. One example is if more than one IDP option meet the amr/acr criteria of the authorize request. In this case, an IDP selector dialog is presented for the user to resolve which IDP to use.


The OIDC Provider also includes a JavaScript Connector supporting all IDPs. The JS Connector is a wrapper for the REST API that simplifies integration for front-end applications and ensures that the REST API is used in the intended way.

Login hints

The OIDC Provider from BankID supports codification of amr values as part of the login_hint request parameter to the authorize endpoint. Hence, pre-selection of the BankID IDP along with pre-selection of user-ID can be governed by suppling proper values as shown in the following table.
