Summary

Follow-up to #184 for the login page, based on the MFA branch because it restructures the login components.

Once a user reaches the failed-attempts threshold, the password and OTP login forms render Turnstile. When the Turnstile iframe cannot be loaded (for example a network error reaching challenges.cloudflare.com), the widget never renders and onError is not always invoked. The password form then answered a submit with "you must check CAPTCHA" while there was nothing to check.

Changes

  • PasswordInputForm and OTPInputForm use the shared TurnstileCaptcha component and useTurnstileCaptcha hook from #184:
    • submitting before a token exists shows "Please wait while we verify you are human, then submit again." and does not post
    • no token after 15 seconds, or a Turnstile error, shows "We couldn't load the security check…" with a Retry security check button
    • an expired token re-runs the widget
    • below the threshold, or with no site key, nothing renders and the form submits as before
  • The OTP form is now gated on the token as well. UserController::postLogin already requires cf-turnstile-response for both flows above the threshold, so the client used to post OTP forms the server would reject.
  • LoginPage no longer holds captcha state: captcha_value, its three handlers, the "you must check CAPTCHA" branch in handleAuthenticateValidation and the componentDidUpdate that only reset it are gone. Each form owns its captcha and remounts when the flow changes.
  • resources/js/components/turnstile_captcha.js, tests/js/components/turnstile_captcha.test.js and tests/js/helpers/turnstile_mock.js are the same files as in #184, so they merge cleanly once both land on main. If fix(auth-ui): recover from Turnstile load failures on auth forms #184 changes in review, these copies need the same change.

#132 (server-side login captcha counter) also touches login.js, so whichever merges second will need a small rebase.

Tests

  • tests/js/login/components/login-captcha.test.js, for both forms: no captcha below the threshold; no onAuthenticate before a token and the waiting message shown; authenticates once a token is issued; retry on error; no gating without a site key. 6 of these fail against the current forms.
  • Full JS suite: npx jest tests/js gives 92 passing, including login.mfa.test.js.

Manual check on the local stack with Cloudflare's always-pass test site key, the login page past the threshold and the challenge iframe blocked: submitting shows the waiting message and sends no POST; after 15 seconds the failure message and retry button appear; unblocking and pressing retry issues a token and clears the message.

Summary by CodeRabbit

  • New Features
    • Added Turnstile CAPTCHA verification to password and one-time-code sign-in when required.
    • Sign-in is blocked until verification succeeds, with status messages while verification is pending.
    • Failed or timed-out verification offers a retry option.

Once the failed-attempts threshold is reached the password and OTP login
forms render Turnstile. When its iframe cannot be loaded the widget never
renders and onError is not always invoked, and the password form answered
a submit with "you must check CAPTCHA" while there was nothing to check.

Use the shared TurnstileCaptcha component and useTurnstileCaptcha hook in
both forms: submitting before a token exists asks the user to wait, no
token after 15s or a Turnstile error shows a failure message with a retry
action, and an expired token re-runs the widget. The OTP form is gated
too, matching UserController::postLogin, which requires the token for
both flows above the threshold.

The captcha state moves out of LoginPage (captcha_value, its three
handlers, the validation branch and the componentDidUpdate reset that only
cleared it): each form owns it and remounts on a flow change.

The shared component, its test and the Turnstile test double are the same
files as in the registration fix (#184).

Walkthrough

The change adds a shared Turnstile CAPTCHA hook and component. Password and OTP login forms use it to block submission until verification succeeds. CAPTCHA state and provider callbacks are removed from the parent login component.

Changes: Login CAPTCHA

Layer / File(s) Summary
Shared CAPTCHA verification
resources/js/components/turnstile_captcha.js, tests/js/components/turnstile_captcha.test.js, tests/js/helpers/turnstile_mock.js
The hook tracks CAPTCHA verification and submission attempts, handles timeouts, errors, and retries, and exposes status messages. The component renders the Turnstile widget and a retry button for failed verification. Tests cover these behaviors.
Login form submission gating
resources/js/login/components/otp_input_form.js, resources/js/login/components/password_input_form.js, resources/js/login/login.js, tests/js/login/components/login-captcha.test.js
The password and OTP forms use the shared CAPTCHA hook and component. They block submission when a required token is unavailable. The parent login component no longer stores CAPTCHA values or passes provider callbacks. Tests cover CAPTCHA-required and CAPTCHA-optional submissions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Low · up to 80e85

Login forms now block submission until a Turnstile token exists and offer a retry when loading fails. The retry-after-script-failure path is not tested against the real widget library, but the library appears to support it, so the risk is small. This is mergeable, and a real-library retry test would be a worthwhile follow-up.

A failed Turnstile script download leaves both login forms blocked despite retries, while the watchdog incorrectly reports a load failure during an ongoing interactive challenge.

What changed in this PR

Moves login CAPTCHA handling into a shared component and hook, extending the recovery approach from #184 to password and OTP login forms.

Changes:

  • Gates both login flows on a Turnstile token when CAPTCHA is required and configured.
  • Adds waiting and failure messages, a retry button, and token-expiry handling.
  • Removes page-level CAPTCHA state and adds shared-component and login-form tests.
File Description
tests/​js/​login/​components/​login-captcha.test.js Tests CAPTCHA gating and recovery in both login forms.
tests/​js/​helpers/​turnstile_mock.js Provides a reusable Turnstile test double.
tests/​js/​components/​turnstile_captcha.test.js Tests shared CAPTCHA states, timeout, retry, and expiry.
resources/​js/​login/​login.js Removes page-level CAPTCHA state and handlers.
resources/​js/​login/​components/​password_input_form.js Uses the shared CAPTCHA component and submission gate.
resources/​js/​login/​components/​otp_input_form.js Adds token gating through the shared CAPTCHA component.
resources/​js/​components/​turnstile_captcha.js Implements shared CAPTCHA status, timeout, and retry handling.

Review effort: Balanced

…retry

Same change to the shared Turnstile component as in
#184 (444cde1), so both copies stay identical:
an interactive challenge is no longer timed out as a load failure, and
retry reloads api.js when the script itself never loaded.

The login captcha test now simulates a loaded api.js, so retry exercises
the widget reset path.

Test retry with the real Turnstile component.

The retry test uses a mock that does not inject api.js, so it cannot detect a failure to reload the script. Add a test that uses @marsidev/react-turnstile and checks that retry inserts a new script and allows the widget to initialize.
