Prompt Authentication

method: probed

scope_note: >-
  Prompt publishes no public API reference, so there is no OpenAPI securitySchemes block to derive
  from. What IS publicly served, from a host Prompt controls, is the OpenID Connect / RFC 8414
  discovery document for the identity provider that fronts the Prompt application. This artifact
  records that surface verbatim from the probe. It describes how a user or a registered client
  authenticates to Prompt's platform — it does NOT document a public product API, and no public
  documentation identifies which resource servers accept these tokens.

observations:
- >-
  `client_credentials` is advertised, which means machine-to-machine tokens are issuable against
  this tenant — the mechanism an integration API would use. No public documentation names the
  audience/resource server, so this cannot be confirmed as a customer-usable API path.
- >-
  The legacy `password` and `implicit` grants remain enabled on the tenant. Both are discouraged by
  OAuth 2.1 / RFC 9700 (BCP 240); `password` is disallowed outright.
- >-
  `plain` is still listed alongside `S256` in code_challenge_methods_supported, a weaker PKCE
  challenge method than S256-only.
- >-
  HS256 is offered as an id_token signing algorithm alongside RS256/PS256.
- No security.txt, OAuth protected-resource metadata, or api-catalog is served on any Prompt host.
