In many cases, you must be logged in with a Hugging Face account to interact with the Hub. Refer to the [Authentication](../quick-start#authentication) section of the documentation to learn more about authentication methods on the Hub.  
It is also possible to log in programmatically by passing your `token` as an argument to [`HfFileSystem`]:  
```python
>>> from huggingface_hub import HfFileSystem
>>> fs = HfFileSystem(token=token)
```
