auth

Start with @warlock.js/auth — JWT auth, Auth base model, authMiddleware route gate, authService (login / logout / refresh), AccessToken + RefreshToken persistence, multi-user-type support. Triggers: `Auth`, `authMiddleware`, `authService`, `AccessToken`, `RefreshToken`, `authMigrations`; "set up auth in a new app", "which auth skill do I need", "JWT authentication overview", "wire warlock auth"; typical import `import { authMiddleware, authService, Auth, authMigrations } from "@warlock.js/auth"`. Skip: routing — `@warlock.js/auth/protect-routes/SKILL.md`; login — `@warlock.js/auth/handle-login-and-logout/SKILL.md`; competing libs `passport`, `next-auth`, `lucia-auth`, `auth0`.

Override the persisted AccessToken / RefreshToken models to add columns (multi-tenant `organization_id`, device metadata), rename, or change storage — without forking the package. Extend the model + `schema.extend(...)`, register it under `config.auth.accessToken.model` / `config.auth.refreshToken.model`, override `issue()` to populate the new column, and add a migration. Triggers: `accessToken.model`, `refreshToken.model`, `AccessToken.issue`, `RefreshToken.issue`, `accessTokenSchema`, `refreshTokenSchema`, "add a column to the token table", "multi-tenant tokens", "organization_id on access token", "override the token model", "custom token storage"; typical import `import { AccessToken, accessTokenSchema } from "@warlock.js/auth"`. Skip: multiple user TYPES (not token storage) — `@warlock.js/auth/customize-user-type/SKILL.md`; the token lifecycle API — `@warlock.js/auth/manage-tokens/SKILL.md`; the config blocks themselves — `@warlock.js/auth/auth-basics/SKILL.md`.

Support multiple user types (user / admin / client / staff) in one auth system — each Auth subclass overrides userType, config.auth.userType.<slug> maps slug to model class, authMiddleware('admin') gates per type. Triggers: `Auth`, `userType`, `config.auth.userType`, `Authenticable`, `@RegisterModel`, `confirmPassword`; "add admins and users", "multiple user types", "separate client and vendor personas", "per-type login"; typical import `import { Auth } from "@warlock.js/auth"`. Skip: `authMiddleware` semantics — `@warlock.js/auth/protect-routes/SKILL.md`; login flow — `@warlock.js/auth/handle-login-and-logout/SKILL.md`; RBAC libs `casl`, `accesscontrol`, `rbac`.

Run the full login flow via authService.login(Model, credentials, deviceInfo?) — verify password, create access + refresh token pair, fire events. Logout via authService.logout(user, accessToken?, refreshToken?) revokes tokens. Triggers: `authService.login`, `authService.logout`, `authService.attemptLogin`, `authService.refreshTokens`, `authService.revokeAllTokens`, `authEvents`; "build a login endpoint", "POST /login controller", "logout from all devices", "verify credentials and issue tokens"; typical import `import { authService, authEvents } from "@warlock.js/auth"`. Skip: token internals — `@warlock.js/auth/manage-tokens/SKILL.md`; sign-up — `@warlock.js/auth/register-user/SKILL.md`; competing libs `passport-local`, `next-auth` credentials.

Token lifecycle — generateAccessToken, createRefreshToken, createTokenPair, refreshTokens (with rotation + replay detection), revokeAllTokens, revokeTokenFamily, cleanupExpiredTokens, getActiveSessions. Triggers: `createTokenPair`, `refreshTokens`, `revokeTokenFamily`, `cleanupExpiredTokens`, `getActiveSessions`, `jwt.generate`, `jwt.verify`, `AccessToken`, `RefreshToken`; "rotate refresh tokens", "detect token replay", "logout from all devices", "list active sessions", "clean up expired tokens"; typical import `import { authService, jwt } from "@warlock.js/auth"`. Skip: login flow — `@warlock.js/auth/handle-login-and-logout/SKILL.md`; CLI cleanup — `@warlock.js/auth/run-auth-commands/SKILL.md`; competing libs `jsonwebtoken`, `jose`, `fast-jwt`.

Front-door orientation for `@warlock.js/auth` — JWT authentication for Warlock apps: the `Auth` base model, `authMiddleware` route gate, `authService` (login / logout / refresh with token rotation + replay detection), persisted AccessToken + RefreshToken, multi-user-type support, auth lifecycle events, and two CLI commands. Coupled to `@warlock.js/core`. TRIGGER when: code imports anything from `@warlock.js/auth`; user asks "what does @warlock.js/auth do", "how do I add login to my Warlock app", "JWT auth in Warlock", "protect a route", "multiple user types / admin + user", "refresh token rotation"; package.json adds `@warlock.js/auth`. Skip: specific task already known — load the matching task skill directly (`auth-basics`, `protect-routes`, `handle-login-and-logout`, `register-user`, `manage-tokens`, `customize-user-type`, `run-auth-commands`); non-Warlock apps (this package depends on core); session-cookie auth (this is JWT/token-based).

Two bundled CLI commands — warlock jwt.generate (creates strong JWT secret + writes to .env) and warlock auth.cleanup (removes expired refresh tokens). Register via registerJWTSecretGeneratorCommand() and registerAuthCleanupCommand(). Triggers: `registerJWTSecretGeneratorCommand`, `registerAuthCleanupCommand`, `warlock jwt.generate`, `warlock auth.cleanup`, `cleanupExpiredTokens`, `command`; "generate JWT secret", "bootstrap .env JWT_SECRET", "cron job for expired tokens", "schedule auth cleanup"; typical import `import { registerJWTSecretGeneratorCommand, registerAuthCleanupCommand } from "@warlock.js/auth"`. Skip: programmatic cleanup — `@warlock.js/auth/manage-tokens/SKILL.md`; in-process scheduling — `@warlock.js/scheduler/scheduler-basics/SKILL.md`; competing tools `dotenv-cli`, `node-cron`.

Brute-force / credential-stuffing protection via `loginThrottleMiddleware` — a failure-aware route gate that counts only failed logins (resets on success), locks per-account and per-source after a threshold, and rejects pre-controller with 429 so the DB lookup and bcrypt verify are skipped. Cache-backed (shared across replicas), fixed-window, fails open on a cache outage. Triggers: `loginThrottleMiddleware`, `AuthErrorCodes.TooManyAttempts`, `EC004`, "rate limit login", "brute force protection", "lock account after failed logins", "throttle login attempts", "too many login attempts 429"; typical import `import { loginThrottleMiddleware } from "@warlock.js/auth"`. Skip: generic per-route request rate limiting that counts every request (use core `middleware.rateLimit`); gating a route by auth — `@warlock.js/auth/protect-routes/SKILL.md`; issuing tokens — `@warlock.js/auth/handle-login-and-logout/SKILL.md`.

Gate HTTP routes via authMiddleware(allowedUserType) — the argument is required and a valid token is always required: [] allows any authenticated user, a user-type restricts to those types. Sets request.user + request.decodedAccessToken on success, 401 on failure. Triggers: `authMiddleware`, `request.user`, `request.decodedAccessToken`, `AuthErrorCodes`, `MissingAccessToken`, `InvalidAccessToken`; "how do I protect a route", "restrict route by user type", "require any logged-in user"; typical import `import { authMiddleware } from "@warlock.js/auth"`. Skip: multi-user-type config — `@warlock.js/auth/customize-user-type/SKILL.md`; issuing the token — `@warlock.js/auth/handle-login-and-logout/SKILL.md`; competing libs `passport`, `express-jwt`, `next-auth` middleware.

Sign up a new user and issue the initial token pair — User.create({...password: await hashPassword(plain)}) then authService.createTokenPair(user). Triggers: `User.create`, `hashPassword`, `verifyPassword`, `authService.createTokenPair`, `toJsonColumns`, `strongPassword`, `authEvents`; "build a register endpoint", "POST /register controller", "sign up a new user", "hash password on signup", "email verification flow"; typical import `import { authService } from "@warlock.js/auth"; import { hashPassword } from "@warlock.js/core"`. Skip: login — `@warlock.js/auth/handle-login-and-logout/SKILL.md`; token internals — `@warlock.js/auth/manage-tokens/SKILL.md`; competing libs `bcrypt`, `bcryptjs`, `argon2`.
