Chrome and Microsoft Edge authentication extension

Enterprise Authentication & NetLog Inspector

Troubleshoot the browser-visible authentication story, from the first protected-resource request through redirects, credentials, tokens, cookies, callbacks, and the final application return.

Selected-request evidence and complete-flow context

See what happened. Keep the evidence attached.

Move from raw browser traffic to a correlated assessment without losing the exact request, response, cookie, token, certificate, or correlation identifier behind each conclusion.

Protocol-aware, vendor-aware

One investigation surface for mixed enterprise identity stacks.

Authentication failures rarely stay inside one product boundary. The inspector keeps evidence from redirects, cookies, headers and payloads in a single sequence.

SAML

Federation messages

HTTP-POST and Redirect bindings, assertions, conditions, signatures, attributes and embedded certificates.

OIDC

OAuth and OpenID Connect

Authorization, callbacks, JWT claims, state, nonce, PKCE, issuer, audience and token lifetime signals.

OAM

OAM and WebGate

Protected resources, server endpoints, authentication cookies, request IDs, ECIDs and application returns.

WNA

Kerberos and NTLM

Negotiate challenges, browser responses, NTLMSSP/Kerberos token classification, fallback detection, and repeated authorization failures.

X.509

Client certificates

Credential-collection endpoints, forwarded certificate headers and browser-visible certificate metadata.

IDP

Okta and Entra ID

Provider recognition, tenant or organization context, provider errors and log correlation identifiers.

NET

Chromium NetLog

Classify Kerberos versus NTLM fallback from client-token evidence, trace challenge retries and outcomes, or investigate TLS, DNS, proxy, socket, HTTP/2, QUIC and raw events.

A repeatable investigation path

From capture to an engineer-ready assessment.

Work live in DevTools, open the toolbar Offline Viewer for a saved HAR or Firefox SAML-tracer JSON export, or investigate a Chromium NetLog. Export a sanitized report for collaboration or retain full correlation values for controlled diagnostic work.

Read the documentation
  1. 01

    Capture or import

    Record the active inspected tab, load the Network HAR, or open Offline Viewer from the extension toolbar to import a saved HAR, Firefox SAML-tracer JSON export, Inspector JSON, or Chromium NetLog trace.

  2. 02

    Reduce the noise

    Filter by protocol, hide static resources and search across browser-visible requests and responses.

  3. 03

    Correlate the evidence

    Use Flow Analysis for authentication transactions or open contextual NetLog investigations for DNS, proxy, TLS, sockets, HTTP and transport failures.

  4. 04

    Share the assessment

    Export sanitized or full-diagnostic Markdown with timelines, correlation keys and server-log guidance.

Privacy by design

Authentication data stays in your browser.

Analysis runs locally inside the extension. Captured traffic, cookies, tokens, SAML messages, authentication headers and imported HAR or NetLog data are not sent to the developer or third parties.

The inspector analyzes browser-visible evidence. Server-to-server exchanges, KDC traffic, backend logs and cryptographic trust validation remain outside that scope.
