Ory Hydra is an OAuth 2.0 and OpenID Connect server; a candidate must satisfy client and token behavior. For Ory Hydra alternatives, test in an isolated environment.
- Exercise authorization code with PKCE, refresh, logout, and token revocation as applicable.
- Verify scopes, audiences, consent, and key rotation.
- Test multiple clients and redirect URI validation, including failure cases.
- Inspect audit logs, rate limits, high availability, and backup.
- Plan migration of clients and sessions without exposing secrets.
A provider with a polished login screen can still be incompatible with existing applications. Use protocol tests and real clients to decide.
