# Signed embedding
> Authenticate iframe-embedded Cube content with secure, server-generated sessions.
Signed embedding is available on [Premium and Enterprise plans](https://cube.dev/pricing).
Signed embedding is designed for **external, customer-facing analytics**. It uses secure, server-generated sessions for authentication, making it ideal for:
* Embedding analytics in your SaaS application for customers
* White-label analytics solutions
* Multi-tenant applications where each customer sees their own data
* Public-facing dashboards with controlled access
Users authenticate through your application without needing Cube accounts, providing a seamless experience. The session tokens are cryptographically signed to ensure secure access with user-specific permissions.
Use signed embedding to embed:
* [Dashboards](/embedding/iframe/dashboards)
* [Analytics Chat](/embedding/iframe/analytics-chat)
* [Creator Mode](/embedding/iframe/creator-mode) (signed embedding is required)
## How it works
Signed embedding works through a two-step authentication flow:
1. **Generate a session** – Your backend generates a temporary session using the Cube API
2. **Exchange for a token** – The iframe automatically exchanges the session for a long-lived access token
**Session lifecycle:**
* **Sessions** are valid for **5 minutes** and must be exchanged within this window
* **Tokens** are valid for **24 hours** after exchange
* Sessions are single-use and expire after being exchanged
This ensures secure authentication while maintaining a smooth user experience.
## Getting started
### Get your API key
To use signed embedding, you need an [API key][ref-api-keys]:
* Go to **Access → API Keys** in your Cube admin panel
* Generate or copy your existing API key
* You'll use this key to authenticate API calls for generating embed sessions
### Generate an embed session
Use the [Generate Session API][ref-generate-session] to create a session for your user. This endpoint will automatically create (insert) or update the external user based on the `externalId` provided.
Accounts are limited to 10,000 external users. To increase this limit, please
contact support.
#### Example (JavaScript)
```javascript theme={null}
const API_KEY = "YOUR_API_KEY";
const DEPLOYMENT_ID = 32;
const session = await fetch(
"https://your-account.cubecloud.dev/api/v1/embed/generate-session",
{
method: "POST",
headers: {
"Content-Type": "application/json",
Authorization: "Api-Key ${API_KEY}",
},
body: JSON.stringify({
deploymentId: DEPLOYMENT_ID,
externalId: "user@example.com",
userAttributes: [
// optional - enables row-level security
{
name: "city",
value: "San Francisco",
},
{
name: "department",
value: "Sales",
},
],
}),
},
);
const data = await session.json();
const sessionId = data.sessionId;
```
### Embed via iframe
Use the session ID to embed the dashboard or chat UI in your application. See [Dashboards](/embedding/iframe/dashboards) and [Analytics Chat](/embedding/iframe/analytics-chat) for the full iframe snippets.
#### Complete example
Here's a complete HTML example that demonstrates the full flow for embedding a dashboard:
```html theme={null}
```
## User attributes
User attributes enable row-level security and personalized chat responses by filtering data based on user permissions. The attributes you pass during session generation automatically filter data queries and responses.
User attributes must first be configured in your Cube admin panel. See the
[User Attributes documentation](/admin/users-and-permissions/user-attributes) for
setup instructions.
**How it works:**
1. **Configure attributes** in your admin panel (e.g., `city`, `department`)
2. **Pass attributes** during session generation
3. **Data is automatically filtered** based on user permissions through access policies
4. **AI responses are personalized** to the user's context
**Example use cases:**
* Sales reps only see data for their assigned territory
* Regional managers see data filtered by their city
* Department heads see only their department's metrics
## Example application
For a complete working example of signed embedding, check out the [cube-embedding-demo](https://github.com/cubedevinc/cube-embedding-demo) repository. This demo application provides:
* A full working example of iframe embedding
* Implementation of signed iframe embedding with session generation
* A React-based UI for testing embedding functionality
* Backend server that securely handles API key authentication
You can clone the repository, configure it with your Cube credentials, and run it locally to test embedding functionality or use it as a reference implementation for your own application.
