To verify that the responses are coming from us, there is a so-called ".wellknown" endpoint that you can use to access information. Inside this endpoint, you can find the "jwks_uri" which is a path to the keys that can be used to verify that the response you receive is from our server.
An example of a .wellknown endpoint (replace "pfzww" with your Base URL):
https://pfzww.audkenni.is/sso/oauth2/realms/root/realms/audkenni/.well-known/openid-configuration
This endpoint will give you a response similar to this:
