## Connect

1. Open **Connections**, choose to connect a service, and select **Hugging Face** with the uses listed above.
2. Give the connection a recognisable name.
3. Fill the settings below in the connection form. Secret fields belong in the credential form, never in chat.
4. Check the connection status and run a connection test where offered.
5. Select this saved connection in the app, workflow step, storage browser, or Assistant task that needs it.

## Connection settings

| Setting | Type | Required | Secret | Explanation |
| --- | --- | --- | --- | --- |
| Access token (optional) (`token`) | password | no | yes | A read-scoped token from huggingface.co/settings/tokens. Optional — anonymous search works with lower limits. |

## Update credentials

Rotate credentials on the saved connection, then test and check a dependent task. A hidden stored secret is not an empty secret. Supply a replacement only when you intend to change it.

## Diagnose a failure

Check the connected account, its permission to the target, the selected folder, table or collection, and the connection’s current status. A successful sign-in is not proof that a particular resource is shared with that account. An empty search or folder page is not necessarily an authentication error. Revoke access when it is no longer needed; deleting the connection can also affect its tools and synced data. See [connection lifecycle](/docs/connections/revoke-and-delete).
