# Stacks Authentication & Authorization The `@stacksjs/auth` package provides comprehensive authentication and authorization for Stacks applications, built on `@stacksjs/ts-auth`. ## Key Paths - Core package source: `storage/framework/core/auth/src/` - Configuration: `config/auth.ts` - Security config: `config/security.ts` - Hashing config: `config/hashing.ts` - Application gates: `app/Gates.ts` - Application middleware: `app/Middleware/` - Middleware aliases: `app/Middleware.ts` - Auth types: `storage/framework/core/types/src/auth.ts` ## Source Files ``` auth/src/ ├── index.ts # All re-exports ├── authentication.ts # Auth class - core auth logic ├── authenticator.ts # 2FA and personal access client ├── client.ts # Client re-exports ├── middleware.ts # Auth middleware handler ├── rate-limiter.ts # RateLimiter class (5 attempts, 15min lockout) ├── passkey.ts # WebAuthn/Passkey support ├── password/reset.ts # Password reset flow ├── register.ts # User registration ├── user.ts # Auth user helpers ├── tokens.ts # Token CRUD, scopes, refresh tokens, OAuth clients ├── gate.ts # Authorization gates & policies ├── policy.ts # BasePolicy class + discovery ├── authorizable.ts # User authorization mixin ├── rbac.ts # Full RBAC system ├── email-verification.ts # Email verification flow └── session-auth.ts # Session-based SPA auth ``` ## Auth Class (authentication.ts) — Static Methods ### Login & Authentication - `Auth.attempt(credentials: AuthCredentials): Promise<boolean>` — validate credentials without creating token - `Auth.validate(credentials: AuthCredentials): Promise<boolean>` — alias for attempt - `Auth.login(credentials: AuthCredentials, options?: TokenCreateOptions): Promise<{ user, token } | null>` — login and create token - `Auth.loginUsingId(userId: number, options?: TokenCreateOptions): Promise<{ user, token } | null>` — login by user ID - `Auth.logout(): Promise<void>` — revoke current token - `Auth.once(credentials: AuthCredentials): Promise<boolean>` — one-time auth without token - `Auth.requestToken(credentials, clientId, clientSecret): Promise<{ token } | null>` — OAuth token request ### User State - `Auth.user(): Promise<UserModel | undefined>` — get authenticated user from bearer token - `Auth.check(): Promise<boolean>` — is user authenticated? - `Auth.guest(): Promise<boolean>` — is user a guest? - `Auth.id(): Promise<number | undefined>` — get authenticated user ID - `Auth.setUser(user: UserModel): void` — manually set user ### Token Creation - `Auth.createTokenForUser(user, options?: TokenCreateOptions): Promise<NewAccessToken>` - `Auth.createToken(user, name?, abilities?): Promise<AuthToken>` ### Token Validation - `Auth.validateToken(token: string): Promise<boolean>` — validate bearer token -

`define<T>(ability: string, callback: GateCallback<T>): void` - `policy(model: string | { name }, policyClass: new () => Policy): void` - `before(callback): void` — run before any gate check - `after(callback): void` — run after any gate check -
