Authentication flows and authenticators should be protocol agnostic. We
currently support both OIDC and SAML. In the future we may add more as well.
With that regards there needs to be a protocol agnostic concept of step-up
authentication. We have some design ideas around it, which involves having
conditions within the authentication flows that handles it rather than
having authenticators to it themselves.
Take a look at https://issues.jboss.org/browse/KEYCLOAK-847 that links to a
Google Doc with some notes
