### Authentication Flow

#### 1. User Authentication

Users can authenticate by sending the `authenticate` event:

```javascript
socket.emit('authenticate', 'api-key');

socket.on('authenticated', (response) => {
    console.log(response);
    // response:
    // {
    //     "status": "success",
    //     "account": "account"
    // }
});
```

#### 2. Unauthenticate

```javascript
socket.emit('unauthenticate', 'api-key');
```
