In `@packages/cli-core/src/commands/security/catalog.ts`:
- Around line 313-316: Update the lockout-threshold check around enabled and
attempts so a missing auth_attack_protection.user_lockout.max_attempts remains
unknown rather than becoming 0. Only report met when the setting is present and
attempts is at most 10; preserve the existing behavior when lockout is disabled
and ensure the displayed attempts value does not imply a configured zero.
- Line 215: Rename the shared check IDs from client-trust to device-trust and
block-disposable-email to block-disposable throughout the CLI commands, JSON
output, documentation, and tests, preserving their existing behavior and
aligning them with the Dashboard catalog.
In `@packages/cli-core/src/commands/security/load.ts`:
- Line 18: Update resolveInstanceId to validate literal linked-profile instance
IDs against app.instances and throw a CliError when the ID is absent; preserve
the existing resolution for valid IDs and eliminate the downstream "unknown"
environment path in resolveEnvironmentType.
In `@packages/cli-core/src/commands/security/README.md`:
- Around line 162-164: Update the security recommendations description to state
that every check except password-min-length, allowlist-on-sign-in, and
oauth-custom-credentials mirrors the Dashboard, correcting the current row-based
grouping.
In `@test/e2e/security-audit.test.ts`:
- Around line 48-50: Set an explicit timeout on the live E2E test containing the
security audit CLI invocation, using the test framework’s per-test timeout
configuration and a value long enough for cold CLI startup and Platform API
calls. Keep the existing command and environment setup unchanged.
- Line 44: Guard the cleanup in afterAll so rmSync is called only when configDir
has been assigned. Preserve recursive, forced removal for valid configDir values
while allowing setup failures to surface their original error.

Grade a Clerk instance against 19 security recommendations read from its Platform API config document, and apply the fixes as one config patch. - `clerk security [audit]` prints the grade, findings grouped by severity with their ids, and exits 1 on unmet gaps at or above --fail-on. JSON in agent mode carries the exact config patch per finding, the suggested decision for MFA and passwordless, and a pinned fix command. - `clerk security fix` opens a checklist; ids, --all (critical and recommended), and --good-to-have select explicitly. mfa and passwordless-auth ask which factors or strategy, or take --factors and --strategy from agents. Patches apply through applyConfigPatch (diff, confirmation, server-side --dry-run) and the result is re-scored from the server's response. - `clerk security checks` lists the catalog offline. Checks match the backend: MFA enrollment is required_for_sign_up, backup codes cannot be the only factor, sign-in breach enforcement needs HIBP on. zxcvbn strength scores and the inactivity timeout are deliberately absent.

[MEDIUM] Choosing email-link here enables magic-link sign-in without turning on email_link_require_same_client
This patch sets auth_email.used_for_sign_in: true and adds email_link to sign_in_strategies. The control that stops cross-device magic-link abuse lives in a separate check, email-link-same-client, which is classified good-to-have — so fix --all skips it (fixableIds(findings, goodToHave) gets false unless --good-to-have is passed) and the interactive picker leaves it unticked. clerk security fix passwordless-auth --strategy email-link --yes therefore turns on email-link sign-in with email_link_require_same_client: false and then reports an improved grade via formatScoreTransition.
The resulting attack is the one the email-link-same-client check's own docsUrl describes: the attacker starts a sign-in in their browser with the victim's email, the victim receives a legitimate Clerk sign-in email and clicks it, and verifying the link completes the attempt that originated in the attacker's browser, giving them a session for the victim's account. It is worse on a phone-signup instance, where appliesTo: ({ config }) => emailEnabled(config) keys off auth_email.used_for_sign_up and drops the check from the report entirely, so a follow-up audit never surfaces the gap the fix just created.
Suggest including auth_attack_protection: { email_link_require_same_client: true } in this patch when the resolved strategy is email-link, or promoting email-link-same-client out of good-to-have once email-link sign-in is on.
