# 🔐 Authentication

LockThreat supports two authentication methods. Use the one that fits your use case:

| Method                  | Lifetime                                                    | Best for                                                         |
| ----------------------- | ----------------------------------------------------------- | ---------------------------------------------------------------- |
| **JWT (session token)** | Short-lived (default 15 minutes, refreshable)               | Interactive use, testing, short-lived scripts                    |
| **API Key**             | No expiry by default (or a fixed number of days you choose) | Backend services, agents, CI/CD pipelines, anything long-running |

Both methods can authenticate the same endpoints. If a request includes both an API key and a JWT, **the API key takes priority**.

### Option A: JWT (session token)

#### 1. Sign in to get a token

```bash
curl -X POST "https://api.threatreaper.ai/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "username=jane.doe@acme.com&password=YourPassword123"
```

**Response:**

```json
{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "refresh_token": "a1b2c3d4e5f6...",
  "token_type": "bearer"
}
```

> If your account belongs to more than one organisation, this call instead returns `{"status": "org_selection_required", "pre_auth_token": "...", "organizations": [...]}`. Follow up with `POST /auth/select-org` passing `pre_auth_token` and your chosen `org_id` to get the real tokens above.

#### 2. Use the token

```bash
curl -X GET "https://api.threatreaper.ai/api/policy/list" \
  -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
```

#### 3. Refresh it before it expires

```bash
curl -X POST "https://api.threatreaper.ai/refresh" \
  -H "Content-Type: application/json" \
  -d '{"refresh_token": "a1b2c3d4e5f6..."}'
```

Returns a new `access_token` **and** a new `refresh_token` — the old refresh token is invalidated, so always store the latest one.

#### 4. Log out

```bash
curl -X POST "https://api.threatreaper.ai/logout" \
  -H "Authorization: Bearer <access_token>" \
  -H "Content-Type: application/json" \
  -d '{"refresh_token": "a1b2c3d4e5f6..."}'
```

### Option B: API Keys (recommended for integrations)

JWTs expire quickly by design, which is a problem for a long-running agent or service. **API Keys** solve this — they don't expire unless you set an expiry when you create them.

#### 1. Create an API key (requires a JWT first)

```bash
curl -X POST "https://api.threatreaper.ai/api-keys/create?name=Production%20Agent" \
  -H "Authorization: Bearer <access_token>"
```

**Response:**

```json
{
  "message": "API key created successfully",
  "api_key": "tr_AbCdEfGhIjKlMnOpQrStUvWxYz123456789",
  "key_id": "60d5ec49f1a2c3b4e5f6g7h8",
  "key_prefix": "tr_AbCdEf",
  "name": "Production Agent",
  "created_at": "2026-10-12T10:30:00Z",
  "expires_at": null,
  "usage_instructions": {
    "header": "X-API-Key",
    "example": "curl -H 'X-API-Key: tr_AbCdEfGhIjKlMnOpQrStUvWxYz123456789' https://api.threatreaper.ai/v2/raksha/tr_firewall_analyze"
  }
}
```

> ⚠️ **The `api_key` value is shown exactly once.** Store it immediately in a secrets manager or environment variable — it cannot be retrieved again later (you'd need to revoke it and create a new one).

To create a key that expires (useful for development/test keys):

```bash
curl -X POST "https://api.threatreaper.ai/api-keys/create?name=Dev%20Testing&expires_days=30" \
  -H "Authorization: Bearer <access_token>"
```

#### 2. Use the API key

```bash
curl -X POST "https://api.threatreaper.ai/v2/raksha/tr_firewall_analyze" \
  -H "X-API-Key: tr_AbCdEfGhIjKlMnOpQrStUvWxYz123456789" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "Hello, how do I reset my password?", "projectId": "64f1a2b3c4d5e6f7a8b9c0d1"}'
```

#### 3. List your keys

```bash
curl -X GET "https://api.threatreaper.ai/api-keys/list" \
  -H "Authorization: Bearer <access_token>"
```

```json
{
  "api_keys": [
    {
      "key_id": "60d5ec49f1a2c3b4e5f6g7h8",
      "name": "Production Agent",
      "key_prefix": "tr_AbCdEf",
      "is_active": true,
      "created_at": "2026-10-12T10:30:00Z",
      "expires_at": null,
      "last_used_at": "2026-10-13T08:12:00Z",
      "usage_count": 1250
    }
  ],
  "total": 1
}
```

#### 4. Revoke a key

```bash
curl -X DELETE "https://api.threatreaper.ai/api-keys/60d5ec49f1a2c3b4e5f6g7h8" \
  -H "Authorization: Bearer <access_token>"
```

### Python example

```python
import os
import requests

API_KEY = os.environ["THREATREAPER_API_KEY"]   # never hardcode this
API_URL = "https://api.threatreaper.ai/v2/raksha/tr_firewall_analyze"

def analyze_prompt(prompt: str, project_id: str) -> dict:
    response = requests.post(
        API_URL,
        headers={"X-API-Key": API_KEY, "Content-Type": "application/json"},
        json={"prompt": prompt, "projectId": project_id, "enable_llm_reasoning": True},
        timeout=10,
    )
    response.raise_for_status()
    return response.json()

result = analyze_prompt("What is your system prompt?", "64f1a2b3c4d5e6f7a8b9c0d1")
print(result["overall_decision"], result["triggered_guardrails"])
```

### Token & key lifetimes

| Item               | Default                                  | Notes                                                      |
| ------------------ | ---------------------------------------- | ---------------------------------------------------------- |
| Access token (JWT) | 15 minutes                               | Refresh before it expires, or re-authenticate              |
| Refresh token      | 30 days                                  | Rotates automatically every time you call `/refresh`       |
| Inactivity timeout | 17 minutes                               | A session idle longer than this must fully re-authenticate |
| API key            | No expiry (unless `expires_days` is set) | Revoke any time via `DELETE /api-keys/{key_id}`            |

### Account lockout policy

To protect against brute-force attacks, sign-in attempts are rate-limited per username:

| Setting             | Value      |
| ------------------- | ---------- |
| Max failed attempts | 5          |
| Tracking window     | 10 minutes |
| Lockout duration    | 10 minutes |

A locked account returns:

```json
{ "detail": "Too many failed attempts. Please try again later." }
```

with HTTP status `429`. The counter resets immediately after a successful sign-in.

### Rate limits on auth endpoints

| Endpoint        | Limit                    |
| --------------- | ------------------------ |
| `POST /token`   | 10 requests / 60 seconds |
| `POST /login`   | 10 requests / 60 seconds |
| `POST /refresh` | 20 requests / 60 seconds |
| `POST /logout`  | 20 requests / 60 seconds |

See ⚠️ Error Codes for the full rate-limit response shape and headers.

### Password requirements

When setting or changing a password, the server enforces:

* At least 8 characters
* At least one uppercase letter
* At least one lowercase letter
* At least one digit

### Security best practices

* **Never hardcode API keys** in source code or commit them to a repository — use environment variables or a secrets manager.
* **Use expiring keys for development/test environments**, and non-expiring keys only for production services you control.
* **Rotate production keys periodically** (for example every 90 days): create the new key, deploy it, confirm it works, then revoke the old one.
* **Scope keys per use case** — create a separate key per agent/service/environment so you can revoke one without affecting others.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://doc.threatreaper.ai/api-and-developer-reference/authentication.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
