AuthTailor 1.0.0 is out (8 November 2026): the SAML & OIDC tracer as an extension of its own – free, no account, no server. What’s inside → +43 664 1964199Contact →

Live capture

The quickest way to a finding: click Record live, log in in the tab next to it, Stop. AuthTailor records only the login requests and masks secrets as it goes.

Start a recording

The box Record live in the browser sits at the top of Auth Trace. No upload: start, then log in in any tab – only SAML, OAuth and OIDC requests are recorded.

Box Record live in the browser with the Record live button and the options Also bearer tokens and Headers
Before starting: the button and two options.
  1. Record live starts the recording.
  2. Also bearer tokens – JWTs from the Authorization header of API calls, e.g. to see why an API answers 401. Off whenever the panel opens.
  3. Headers – request and response headers of the login steps, masked. On by default; the panel remembers your choice.
  1. Choose the options. They cannot be changed while recording.
  2. Click Record live. The first time, allow access to all https sites.
  3. Trigger the login in the tab next to it – open the app, click Sign in, log in at the identity provider.
  4. Wait until the app is signed in, then click Stop in the panel.

If you refuse the access, the panel says “Without the permission the browser cannot record – paste or drop a HAR instead.” The HAR route is described in Paste and examples.

While recording

Running recording with a red marker, the Recording line and the Stop button
The recording is running.
  1. Recording keeps count – without bearer tokens the login requests, with the option as here all captured requests. Below: “Log in now in a tab. Stops by itself in 30 min.” and how many requests the browser has seen in tabs in total.
  2. Stop ends the recording.

You log in as usual in a tab. The images of these docs show a made-up app “Acme Orders” with the identity provider login.acme.example:

Login page Acme Demo Login of the made-up identity provider in the tab next to the panel
The login runs in a normal tab – here a made-up demo.

As soon as login requests arrive, the result appears while recording and grows:

Running recording with eight captured requests, the line Authorization headers seen and the verdict below
With “Also bearer tokens”: login and API calls in one recording.
  1. With Also bearer tokens the line counts requests captured (login and bearer tokens).
  2. Authorization headers seen: how many were JWTs, opaque tokens or Basic. AuthTailor only takes JWTs.
  3. The verdict is already there – here the API rejects the token with insufficient_scope.

After stopping

After stopping: buttons Record again, Save cleaned HAR, Copy report, links Clear and Back to paste, verdict and security rating
After stopping: result, actions and notes about the recording.
  1. Record again starts a new recording and replaces the old one.
  2. Save cleaned HAR saves the recording masked as authtrace-live.sanitized.har; next to it Copy report copies verdict, rating, flows, findings and steps as Markdown.
  3. Clear discards the recording, Back to paste shows the paste field again. Behind them: what the recording contains and what not.
  4. The verdict – how to read it is described in Reading the result.
  5. The Security rating as a traffic light per area.

What is recorded

RecordedNot recorded
SAML in URL or form (SAMLRequest, SAMLResponse, RelayState)Response bodies – use a HAR for token responses
OAuth and OIDC parameters (code, state, nonce, PKCE, redirect_uri, errors)Requests that are not part of the login (images, scripts, app data)
Token, discovery and JWKS calls, logoutsBasic credentials and opaque tokens
With Headers: request and response headers of these steps, masked; without the option only LocationCookie values, passwords, client secrets (masked)
With Also bearer tokens: Authorization: Bearer with a JWT, the response’s WWW-Authenticate, DPoP proofsRefresh tokens in clear – only a short hash, so rotation stays visible

Everything stays in the panel’s memory while it is open. Close the panel and the recording is gone. More in Permissions and privacy.

Limits

  • A recording ends by itself after 30 minutes and holds up to 300 requests.
  • Server-to-server flows (client credentials, SAML bearer, on-behalf-of) are invisible to the browser. Paste the token request or the token instead.
  • Token responses carry their content in the response body. The recording does not read it – but with Also bearer tokens you see the tokens in the API calls, or you export a HAR.

Frequently asked

Short answers.

Do I need to export a HAR first?
No. The live capture replaces the export from the DevTools. You only need a HAR to see response bodies such as the token response.
Does the recording continue when I switch tabs?
Yes. A running recording continues as long as the panel is open. Closing the panel ends it.
Does the host access stay granted after recording?
No. AuthTailor requests the access when starting and gives it back when stopping. About › Permissions shows the current state.
