Official Cognito documentation says a lot about how to federate other OIDC providers in a user User Pool, but I cannot find proper documentation explaining how to use the User Pool as an OIDC provider by itself. This is for scenarios where Clients will authenticate against the Cognito User Pool with the OIDC protocol without involving any other Identity Providers.
It seems to be compatible, for the following endpoint exists:
https://cognito-idp.<region>.amazonaws.com/<user pool id>/.well-known/openid-configuration
Where's the documentation for that?
I can only find third-party articles about this, but no proper documentation from AWS.
I submitted some feedback via GitHub. The fact that it supports OIDC should be displayed more prominently and at a higher level in the page tree. It was difficult to find it without asking.
