A CLOSER LOOK

The details behind
the result.

Understand the format, the calculation, and what to look for.

OIDC

Compare HTTPS discovery endpoints and supported grants. JWT verification requires an explicit issuer, audience and trusted JWKS; no token-provided key URL is followed.

Service clients

Client Credentials sends one authorized request and masks token material. No production credential storage, refresh loop, automatic revocation or user-password collection occurs.

SAML scope

Metadata and assertion structure inspection only. XML signature, trust-chain, replay protection, PKCE login and SP-initiated sessions are not implemented by this inspector; parsing is never reported as authentication success.
