Summary

  • UserController::verify2FA now returns the recovery-codes standing (recovery_codes_remaining, recovery_codes_total, recovery_codes_low_threshold) alongside redirect_url, reusing RecoveryCodesStatus::toArray() exactly as verify2FARecovery does.
  • The login SPA extracts the warning decision into proceedAfterVerifiedLogin(), used by both onVerify2FA() and onVerifyRecovery(). The warning is shown before window.location.href is set; dismissal is remembered per browser session for both paths.
  • The warning block no longer depends on the recovery form being active, and TwoFactorForm is hidden while it shows, so it renders after an OTP verification.

Out of scope

Enrollment modal for 0 unused codes, and trusted-device sign-ins that skip the challenge.

Test plan

  • docker exec idp-app ./vendor/bin/phpunit tests/TwoFactorLoginFlowTest.php (66 tests, 0 failures)
  • yarn test:unit:ci (12 suites, 70 tests, 0 failures)
  • Manual: user with 2 unused codes signs in via email OTP and sees the warning before redirect; 3+ codes redirects directly; dismissed warning not shown again in the same session

Summary by CodeRabbit

New Features

  • Sign-in displays a warning before navigation when recovery codes are below the configured threshold. Recovery-code sign-in also warns when no codes remain; OTP sign-in does not warn when none remain.
  • Dismissing the warning suppresses it for the rest of the browser session.
  • Successful two-factor sign-in responses include recovery-code availability, counting only unused codes.

Bug Fixes

  • Sign-in can still complete if recovery-code availability cannot be retrieved; availability details are omitted in that case.

Walkthrough

Successful OTP and recovery-code verification responses now include recovery-code status when available. The login page uses that status to show a low-code warning or continue to the redirect destination. Status retrieval failures do not block sign-in.

Changes: Recovery-Code Warning

Layer / File(s) Summary
Return recovery-code status
app/Http/Controllers/UserController.php, tests/TwoFactorLoginFlowTest.php
Successful OTP and recovery-code responses use a shared helper to retrieve recovery-code status. If retrieval fails, the helper logs a warning and returns an empty array. Tests cover status counts and successful sign-in when status retrieval throws.
Share warning and redirect handling
resources/js/login/login.js, tests/js/login/login.mfa.test.js
Successful OTP and recovery-code verification use shared warning and redirect handling. The warning appears below the configured threshold, including zero remaining after recovery-code verification. The two-factor form is hidden while the warning is active. Tests cover threshold behavior and session dismissal.

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

Merge Risk: Low · previous review e5026

After email OTP sign-in, users with few recovery codes now see a warning before the redirect. Minor edge cases remain: blocked browser storage can stall the redirect, removing the account chip while the warning is open leaves a stale warning, and screen-reader users are not told the form was replaced. These are limited in scope and none is likely to break normal sign-in.

@romanetar romanetar self-assigned this Nov 5, 2026
verify2FA now returns the recovery-codes standing (same payload as
verify2FARecovery) and the login SPA shares one helper for both paths to
show the low-codes warning before navigating to redirect_url. The warning
block no longer depends on the recovery form so it renders after an OTP
verification too.
A user who passes the email OTP challenge with no unused recovery codes
most likely never generated any (codes are only created on enrollment or
explicit regeneration), so "you have 0 recovery codes left" is misleading
there. Only warn on the OTP path when 0 < remaining < threshold; the
recovery-code path still warns at 0, since the user just burned their
last code.
…ication

verify2FA() and verify2FARecovery() read the recovery-codes standing after
the second factor is redeemed, the session is established and postLogin()
may have consumed the OAuth2 memento. A failure there turned the sign-in
into a 500 without redirect_url. Log it and return redirect_url without
the status fields instead; the login page already navigates directly when
they are absent.

Review comments at @resources/js/login/login.js:
- Line 923: Update handleDelete and the account-removal flow so removing an
account during a pending redirect cannot leave lowRecoveryCodesWarning beside
the initial sign-in UI or let Continue use the previous account’s redirect URL.
Either prevent account removal until the redirect completes or cancel the
completed sign-in consistently, clearing its warning and stale redirect state.
- Line 923: Update the lowRecoveryCodesWarning rendering in TwoFactorForm’s
parent so the warning is announced when OTP verification hides TwoFactorForm,
and manage focus so users can proceed to Continue without losing keyboard
context. Add a rendered-component test covering this transition and verifying
the warning announcement and focus behavior.

…rect intact

Announce the warning (role=alert) and focus Continue when the verify form
unmounts, and hide the account chip's delete action while the warning is
pending: the sign-in already completed server-side, so removing the
account there left the warning beside a fresh sign-in form and cancelled
the OAuth2 request behind its redirect.
