Darrow Authentication

note: >-
  Darrow publishes no public API reference, so this profile is derived entirely from the
  OpenID Connect discovery document its Auth0 tenant serves anonymously. It describes how
  the Darrow customer portal authenticates users — it is NOT a published developer
  authentication scheme, and no API key, client-credential issuance flow or token
  documentation is available to the public.

  token_exchange: true
  request_parameter_supported: false
  request_uri_parameter_supported: false
observations:
- The tenant still advertises the legacy `password` and `implicit` grants alongside
  authorization_code + PKCE; both are discouraged by OAuth 2.1.
- HS256 remains in id_token_signing_alg_values_supported, so a symmetric-signed ID token
  is possible for clients configured that way.
- No /.well-known/oauth-protected-resource document is served (404), so there is no
  published resource-server metadata binding an API audience to this issuer.
