# [Azure Artifacts](#azure-artifacts)

uv can install packages from [Azure Artifacts](https://learn.microsoft.com/en-us/azure/devops/artifacts/start-using-azure-artifacts?view=azure-devops&tabs=nuget%2Cnugetserver), either by using a [Personal Access Token](https://learn.microsoft.com/en-us/azure/devops/organizations/accounts/use-personal-access-tokens-to-authenticate?view=azure-devops&tabs=Windows) (PAT), or using the [`keyring`](https://github.com/jaraco/keyring) package.

To use Azure Artifacts, add the index to your project:

pyproject.toml

```
[[tool.uv.index]]
name = "private-registry"
url = "https://pkgs.dev.azure.com/<ORGANIZATION>/<PROJECT>/_packaging/<FEED>/pypi/simple/"
```

## [Authenticate with an Azure access token](#authenticate-with-an-azure-access-token)

If there is a personal access token (PAT) available (e.g., [`$(System.AccessToken)` in an Azure pipeline](https://learn.microsoft.com/en-us/azure/devops/pipelines/build/variables?view=azure-devops&tabs=yaml#systemaccesstoken)), credentials can be provided via "Basic" HTTP authentication scheme. Include the PAT in the password field of the URL. A username must be included as well, but can be any string.

For example, with the token stored in the `$AZURE_ARTIFACTS_TOKEN` environment variable, set credentials for the index with:

```
export UV_INDEX_PRIVATE_REGISTRY_USERNAME=dummy
export UV_INDEX_PRIVATE_REGISTRY_PASSWORD="$AZURE_ARTIFACTS_TOKEN"
```

Note

`PRIVATE_REGISTRY` should match the name of the index defined in your `pyproject.toml`.

## [Authenticate with `keyring` and `artifacts-keyring`](#authenticate-with-keyring-and-artifacts-keyring)

You can also authenticate to Artifacts using [`keyring`](https://github.com/jaraco/keyring) package with the [`artifacts-keyring` plugin](https://github.com/Microsoft/artifacts-keyring). Because these two packages are required to authenticate to Azure Artifacts, they must be pre-installed from a source other than Artifacts.

The `artifacts-keyring` plugin wraps the [Azure Artifacts Credential Provider tool](https://github.com/microsoft/artifacts-credprovider). The credential provider supports a few different authentication modes including interactive login — see the [tool's documentation](https://github.com/microsoft/artifacts-credprovider) for information on configuration.

uv only supports using the `keyring` package in [subprocess mode](../../../reference/settings/#keyring-provider). The `keyring` executable must be in the `PATH`, i.e., installed globally or in the active environment. The `keyring` CLI requires a username in the URL, and it must be `VssSessionToken`.

```
# Pre-install keyring and the Artifacts plugin from the public PyPI
uv tool install keyring --with artifacts-keyring

# Enable keyring authentication
export UV_KEYRING_PROVIDER=subprocess

# Set the username for the index
export UV_INDEX_PRIVATE_REGISTRY_USERNAME=VssSessionToken
```

Note

The [`tool.uv.keyring-provider`](../../../reference/settings/#keyring-provider) setting can be used to enable keyring in your `uv.toml` or `pyproject.toml`.

Similarly, the username for the index can be added directly to the index URL.

## [Publishing packages](#publishing-packages)

If you also want to publish your own packages to Azure Artifacts, you can use `uv publish` as described in the [Building and publishing guide](../../package/).

First, add a `publish-url` to the index you want to publish packages to. For example:

pyproject.toml

```
[[tool.uv.index]]
name = "private-registry"
url = "https://pkgs.dev.azure.com/<ORGANIZATION>/<PROJECT>/_packaging/<FEED>/pypi/simple/"
publish-url = "https://pkgs.dev.azure.com/<ORGANIZATION>/<PROJECT>/_packaging/<FEED>/pypi/upload/"
```

Then, configure credentials (if not using keyring):

```
$ export UV_PUBLISH_USERNAME=dummy
$ export UV_PUBLISH_PASSWORD="$AZURE_ARTIFACTS_TOKEN"
```

And publish the package:

```
$ uv publish --index private-registry
```

To use `uv publish` without adding the `publish-url` to the project, you can set `UV_PUBLISH_URL`:

```
$ export UV_PUBLISH_URL=https://pkgs.dev.azure.com/<ORGANIZATION>/<PROJECT>/_packaging/<FEED>/pypi/upload/
$ uv publish
```

Note this method is not preferable because uv cannot check if the package is already published before uploading artifacts.
