Configuring the client registration for Pega Infinity Mobile Client authentication against an external OIDC server

Configure client registration to increase the security of your application, by enabling authentication against an external OpenID Connect (OIDC) identity provider (IdP) for Pega Infinity Mobile Client.
Before you begin: Register your application with an external OIDC IdP, for example, Google, and then obtain the parameters that you must then enter in Pega Platform. For the list of parameters to gather, see Custom parameters for direct authentication against an external OIDC server.
Note: Ensure that the OIDC IdP derives the Audience claim from the Client ID value. For more information, see the documentation for the selected OIDC IdP.
