feat(2fa): recovery-code enrollment modal and batch acknowledgment - #183
Implements ClickUp 86bcy7rv7 against SDS idp-mfa.md rev 2.5 and rev 2.6 (ftn-docsnsklz PR #179, still a draft).
Based on feat/mfa-phase1---migrations--and--interfaces (#125), so the diff is a single commit.
Problem
A group-enforced admin who never opens the profile has no recovery codes, and the system cannot tell whether a user ever saved the batch it showed (the profile counts unused rows, so an unsaved batch reads "10 of 10 remaining"). POST 2fa/enable also let an enforced admin mint a batch without the password.
What changes
A user who requires 2FA and has no usable batch (none, exhausted or unacknowledged) is challenged at every sign-in, trusted device included, and gets the non-dismissable "Save Your Recovery Codes" modal right after the challenge. A batch counts as usable only after the user confirms it, bound to the exact batch shown. See ADR 0002 (supersedes 0001).
RecoveryCodesBatch: the generation methods return the codes and the batch id read inside the same locked transaction, so a concurrent regeneration cannot pair dead codes with another batch's id.
Every path that writes or deletes codes (generation, acknowledgment, redemption) locks the users row first and re-hydrates the entity (lockUserRow()); a plain EntityManager::lock() would leave stale state.
POST recovery-codes/enroll (inside two_factor.recovery_enrollment_window of a real challenge, 5 per 15 min per authenticated user) and POST recovery-codes/acknowledge. 2fa/enable answers 412 for users who already require 2FA. regenerate accepts a user without a password inside the window.
Authenticate stops redirecting JSON requests to the session backurl.
Frontend
Login page enrolls, shows the modal and navigates only after the batch is acknowledged; an enrollment failure never blocks the sign-in.
Profile panel renders the server's status keys and enrolls only when the user clicks "Set up recovery codes", never on load.
Deviation from the ticket: CSRF token
The ticket's gotcha says the login page CSRF token survives Auth::login(). It does not: SessionGuard::updateSession() calls Session::regenerate(true), which also rotates the token. The enroll and acknowledge calls the page makes right after the challenge would get a 419. verify2FA and verify2FARecovery therefore return the current csrf_token and login.js sends it. The ticket's "token is the same before and after verify2FA" assertion cannot hold, so the test asserts that it rotates and that the response carries the new one.
Also added recovery_codes_window_open to the profile view: the ticket's recovery_codes_enrollment_available does not tell a user without a password whether they can regenerate inside the window once the batch is already acknowledged.
2fa/disable / 2fa/method rules belong to ticket 14.
Test plan
phpunit full suite: 760 tests, 4 failures (OAuth2EndSessionTest, PasswordChangeRevokeTokenTest), which fail identically without these changes.
New PHP tests: enrollment service matrix, window, backfill migration, endpoints, rate limit right after verify2FA, backurl handling, trusted-device gate.
Concurrency tests with real child processes (two generations leave one batch; a replaced code is rejected during regeneration). With the lock disabled all four fail and generation leaves 20 rows.
yarn test:unit:ci: 97 tests pass.
Playwright against http://localhost:8001: the new recovery-code-enrollment.spec.ts (real sign-in, real CSRF), auth-code-flow and login-mfa-flow all pass. The docker e2e profile cannot sign in locally because the session cookie is secure over plain http://nginx.
CI adds mfa-enroll@test.com to the seeded e2e users (both frontend workflows).
Deployment Notes
Migration: Version20261105120000 adds nullable users.recovery_codes_acknowledged_at and backfills it in postUp() for users who already hold unused recovery codes. Run it before the new code serves traffic; the column is nullable, so the old code tolerates it.
Doctrine: User gained a mapped field. Regenerate the proxies and clear the metadata cache (./update_doctrine.sh), or the cached mapping will miss the column.
Config / env (optional, defaults shown):
TWO_FACTOR_RECOVERY_ENROLLMENT_WINDOW=600 (seconds after a 2FA challenge during which codes can be enrolled/regenerated without a password)
TWO_FACTOR_MAX_ENROLL_REQUESTS=5
TWO_FACTOR_ENROLL_WINDOW_MINUTES=15
Run php artisan config:clear (or config:cache) if config is cached.
Frontend: yarn build (login page and profile bundles changed).
User-facing impact: after deploy, every user who requires 2FA and has no unused recovery codes is challenged at the next sign-in, even on a trusted device, and must save the new codes in a modal they cannot dismiss. The same applies to users who never had codes or used them all. Users with unused codes are backfilled as acknowledged and see no change.
This change adds recovery-code enrollment and acknowledgment after MFA challenges. Recovery-code batches now include identifiers and acknowledgment status. The change also adds enrollment-window and rate-limit controls, login and profile flows, persistence updates, and tests.
Changes: Recovery-code enrollment and acknowledgment
Recovery-code generation returns a batch ID with its plaintext codes. The service tracks acknowledgment and enrollment status, checks the post-MFA enrollment window, and locks the user row before recovery-code operations. The migration adds and backfills acknowledgment timestamps. Tests cover enrollment status, migration backfill, and concurrent generation and redemption.
MFA verification records a completion marker and returns a fresh CSRF token and recovery-code status. Authenticated endpoints enroll and acknowledge batches. Enrollment uses configurable limits and is required before device trust can bypass an MFA challenge. JSON authentication requests continue without consuming the session back URL.
The login and profile interfaces send enrollment and acknowledgment requests and display batches in a modal. The modal handles pending, error, retry, and acknowledgment states. JavaScript and end-to-end tests cover the enrollment flow; the frontend test workflows create an MFA test account.

Merge Risk: Low · previous review c2e01
After a replaced recovery-code batch, users can confirm the new codes without the intended brief delay. One OAuth e2e test may also be flaky. Both are small fixes that can be made before merge or as a follow-up.

- Around line 933-944: Ensure RecoveryCodeModal restarts its acknowledge
countdown when recoveryEnrollment is replaced with a new code batch, even while
the modal remains open. Tie the modal’s countdown lifecycle to the batch
identity, using an existing batch identifier if available, so the new codes
cannot be acknowledged until their countdown completes.
Review comments at @tests/e2e/tests/oauth2/auth-code-flow.spec.ts:
- Around line 94-102: Update the OAuth code-flow setup around
acknowledgeRecoveryCodesModal and page.goto to prevent the
acknowledgment-triggered navigation from racing the test redirect. Preserve the
browser’s original origin when resolving the redirect, rather than using the
app’s potentially different configured domain, and ensure the navigation
sequence does not interrupt page.goto.

… for the post-acknowledge navigation in e2e
Review feedback on #183.
- RecoveryCodeModal: the 5 second read-before-confirm delay restarted only when
`open` changed. On the login page a 412 from acknowledge re-enrolls and swaps
the codes while the modal stays open, so the new batch could be confirmed
immediately. The countdown now also restarts when the displayed codes change
(keyed by content, so an equal array passed again does not reset it).
- e2e helper acknowledgeRecoveryCodesModal: optional `expectNavigation` waits for
the load event of the navigation the login page starts after acknowledging,
so the page.goto that follows cannot race it. Used by the login flows; the
profile panel does not navigate, so it keeps the default.
…them only once acknowledged
A user who requires 2FA and has no usable batch of recovery codes (none,
exhausted or unacknowledged) is now challenged at every sign-in, trusted
device included, and gets the non-dismissable "Save Your Recovery Codes"
modal right after the challenge. A batch counts as usable only after the
user confirms it, and the confirmation is bound to the exact batch shown
(SDS idp-mfa.md rev 2.5 + 2.6, ClickUp 86bcy7rv7).
Backend
- users.recovery_codes_acknowledged_at with a backfill migration.
- RecoveryCodesBatch: the generation methods return the codes and the batch
id read inside the same locked transaction, so a concurrent regeneration
cannot pair dead codes with another batch's id.
- Every path that writes or deletes codes (generation, acknowledgment,
redemption) locks the users row first and re-hydrates the entity.
- POST recovery-codes/enroll (window after a real challenge, 5 per 15 min
per authenticated user) and recovery-codes/acknowledge; 2fa/enable is
rejected for users who already require 2FA; regenerate accepts a user
without a password inside the enrollment window.
- Auth::login() regenerates the session CSRF token, so verify2FA and
verify2FARecovery return the current csrf_token for the calls that follow.
- Authenticate no longer redirects JSON requests to the session backurl.
Frontend
- Login page enrolls, shows the modal and navigates only after the batch is
acknowledged; enrollment failures never block the sign-in.
- Profile panel renders the server's status keys and enrolls only when the
user clicks "Set up recovery codes".

…rver
jest covers every panel state in isolation; this spec proves the pieces work
together on the profile page: the real status keys of the profile view, the
real CSRF check on enroll / regenerate / acknowledge, nothing generated on
load or reload, the batch not counted until it is acknowledged, and the
panel's buttons never submitting the page's enclosing form.
It is a single test made of steps because the steps share the signed-in
session and the account's recovery codes. CI seeds its user,
mfa-profile@test.com, in both frontend workflows.
