Use Cognito as primary identity provider for non-AWS-hosted applications?

Question

Hello,

Is it possible to use Cognito as primary identity provider for non-AWS-hosted applications?

AUTHENTICATION: It seems to be possible to do authentication via the Cognito User Pools.
I see it returns an access token after authentication:

DOWNSTREAM AUTHORIZATION: Assuming trust with the downstream non-AWS-hosted service provider, I'm not sure how any authorization could happen within this service provider considering I don't see any standard token (SAML...) being provided by Cognito. Any way to forward a standard token to a downstream non-AWS-hosted service provider?

Thanks!

Accepted Answer

You can accomplish custom authorization in your downstream apps by using the Cognito User Pool Groups. You can place your users into groups on the Cognito side. The JWT ID Token will contain the role values associated with the user in the cognito:roles claim. You will then grant the appropriate authorization level based on the role that the user is assigned.
