# bkend.ai Authentication & Security Guide

## Auth Methods

| Method | Description |
|--------|-------------|
| Email + Password | Email/password signup and login |
| Social (Google) | OAuth 2.0 social login |
| Social (GitHub) | OAuth 2.0 social login |
| Magic Link | Email link login (no password) |

## JWT Token Structure

- **Access Token**: 1 hour validity
- **Refresh Token**: 7 days validity
- Auto-refresh: `POST /v1/auth/refresh`

## Password Policy

8+ characters, uppercase + lowercase + numbers + special characters

## MCP Auth Workflow

bkend MCP does NOT have dedicated auth tools. Use this workflow:

1. **Search docs**: `search_docs` with query "email signup" or "social login"
2. **Get examples**: `search_docs` with query "auth code examples"
3. **Generate code**: AI generates REST API code based on search results

### Searchable Auth Docs
| Doc ID | Content |
|--------|---------|
| `3_howto_implement_auth` | Signup, login, token management guide |
| `6_code_examples_auth` | Email, social, magic link code examples |

### Key Pattern
```
User: "Add social login"
  → search_docs(query: "social login implementation")
  → Returns auth guide with REST API patterns
  → AI generates social login code
```

## REST Auth API (Core Endpoints)

For the complete endpoint list, use `search_docs` or check Live Reference.

| Method | Endpoint | Description |
|--------|----------|-------------|
| POST | /v1/auth/email/signup | Sign up |
| POST | /v1/auth/email/signin | Sign in |
| GET | /v1/auth/me | Current user |
| POST | /v1/auth/refresh | Refresh token |
| POST | /v1/auth/signout | Sign out |
| GET/POST | /v1/auth/:provider/callback | Social login callback |
| POST | /v1/auth/password/reset/request | Password reset |
| POST | /v1/auth/password/reset/confirm | Confirm reset |
| POST | /v1/auth/password/change | Change password |
| GET | /v1/auth/sessions | List sessions |
| DELETE | /v1/auth/sessions/:sessionId | Remove session |
| DELETE | /v1/auth/withdraw | Delete account |

**Additional endpoints** (MFA, invitations, user management): use `search_docs` or Live Reference.

## RBAC (Role-Based Access Control)

| Group | Description | Scope |
|-------|-------------|-------|
| admin | Full CRUD | All data |
| user | Authenticated user | Full read, own write |
| self | Owner only | createdBy-based |
| guest | Unauthenticated | Read only (usually) |

## RLS (Row Level Security)

- Per-table row-level access control
- 4-level policies: admin/user/self/guest
- Auto-filtering based on createdBy field

## Session Management

- Per-device session tracking
- `GET /v1/auth/sessions` - List sessions
- `DELETE /v1/auth/sessions/:sessionId` - Remove session
