Overview

OpenID Connect (OIDC) allows your {% data variables.product.prodname_actions %} workflows to authenticate with PyPI to publish Python packages.

This guide gives an overview of how to configure PyPI to trust {% data variables.product.prodname_dotcom %}'s OIDC as a federated identity, and demonstrates how to use this configuration in the pypa/gh-action-pypi-publish action to publish packages to PyPI (or other Python package repositories) without any manual API token management.

Prerequisites

{% data reusables.actions.oidc-link-to-intro %}

{% data reusables.actions.oidc-security-notice %}

Adding the identity provider to PyPI

To use OIDC with PyPI, add a trust configuration that links each project on PyPI to each repository and workflow combination that's allowed to publish for it.

  1. Sign in to PyPI and navigate to the trusted publishing settings for the project you'd like to configure. For a project named myproject, this will be at https://pypi.org/manage/project/myproject/settings/publishing/.

  2. Configure a trust relationship between the PyPI project and a {% data variables.product.prodname_dotcom %} repository (and workflow within the repository). For example, if your {% data variables.product.prodname_dotcom %} repository is at myorg/myproject and your release workflow is defined in release.yml with an environment of release, you should use the following settings for your trusted publisher on PyPI.

    {% note %}

    Note: Enter these values carefully. Giving the incorrect user, repository, or workflow the ability to publish to your PyPI project is equivalent to sharing an API token.

    {% endnote %}

    • Owner: myorg
    • Repository name: myproject
    • Workflow name: release.yml
    • (Optionally) a {% data variables.product.prodname_actions %} environment name: release

Updating your {% data variables.product.prodname_actions %} workflow

Once your trusted publisher is registered on PyPI, you can update your release workflow to use trusted publishing.

{% data reusables.actions.oidc-deployment-protection-rules %}

The pypa/gh-action-pypi-publish action has built-in support for trusted publishing, which can be enabled by giving its containing job the id-token: write permission and omitting username and password.

The following example uses the pypa/gh-action-pypi-publish action to exchange an OIDC token for a PyPI API token, which is then used to upload a package's release distributions to PyPI.

jobs:
  release-build:
    runs-on: ubuntu-latest

    steps:
      - uses: {% data reusables.actions.action-checkout %}

      - uses: {% data reusables.actions.action-setup-python %}
        with:
          python-version: "3.x"

      - name: build release distributions
        run: |
          # NOTE: put your own distribution build steps here.
          python -m build

      - name: upload windows dists
        uses: {% data reusables.actions.action-upload-artifact %}
        with:
          name: release-dists
          path: dist/

  pypi-publish:
    runs-on: ubuntu-latest
    needs:
      - release-build
    permissions:
      id-token: write

    steps:
      - name: Retrieve release distributions
        uses: {% data reusables.actions.action-download-artifact %}
        with:
          name: release-dists
          path: dist/

      - name: Publish release distributions to PyPI
