OpenID Discovery Viewer

Retrieve and analyze OpenID Provider configuration from the well-known discovery document.

Retrieves /.well-known/openid-configuration from the issuer.

What is OpenID Discovery Viewer?

OpenID Connect discovery publishes a well-known JSON document describing authorization endpoints, JWKS URI, and supported capabilities for an identity provider.

How it works

Enter an issuer URL. PacketWizard retrieves /.well-known/openid-configuration and presents the configuration for federation troubleshooting.

Common issues

  • Trailing slash issuer mismatches

    Issuer strings must match exactly between discovery and tokens. Trailing-slash differences are a common Entra/Auth0 integration bug.

Frequently asked questions

Is discovery required for OAuth?

OAuth 2.0 can work with manual endpoint config. OIDC discovery reduces misconfiguration by advertising endpoints and capabilities centrally.
