## Authentication with alternative package indexes

See the dedicated guides for authentication with popular alternative Python package indexes:

- [Azure Artifacts](../../guides/integration/azure.md)
- [Google Artifact Registry](../../guides/integration/google.md)
- [AWS CodeArtifact](../../guides/integration/aws.md)
- [JFrog Artifactory](../../guides/integration/jfrog.md)

## Hugging Face support

uv supports automatic authentication for the Hugging Face Hub. Specifically, if the `HF_TOKEN`
environment variable is set, uv will propagate it to requests to `huggingface.co`.

This is particularly useful for accessing private scripts in Hugging Face Datasets. For example, you
can run the following command to execute the script `main.py` script from a private dataset:

```console
$ HF_TOKEN=hf_... uv run https://huggingface.co/datasets/<user>/<name>/resolve/<branch>/main.py
```

You can disable automatic Hugging Face authentication by setting the `UV_NO_HF_TOKEN=1` environment
variable.
