# Setting up PyPI

1. Create the following environment variables depending on the authentication method:
   
   {% list tabs group=registry_auth %}
   
   - IAM token {#iam-token}
   
     1. Get an [IAM token](../../../iam/concepts/authorization/iam-token.md) for the [Yandex account](../../../iam/operations/iam-token/create.md) or [service account](../../../iam/operations/iam-token/create-for-sa.md) you are going to use for authentication.
     1. Create the `REGISTRY_USERNAME` and `REGISTRY_PASSWORD` environment variables:
   
         ```bash
         export REGISTRY_USERNAME="iam"
         export REGISTRY_PASSWORD="<IAM_token>"
         ```
   
         Where:
   
         * `REGISTRY_USERNAME`: Authentication method.
         * `REGISTRY_PASSWORD`: Body of the previously obtained IAM token.
   
     {% note info %}
   
     The IAM token's [lifetime](../../../iam/concepts/authorization/iam-token.md#lifetime) is limited to 12 hours.
   
     {% endnote %}
   
   - API key {#api-key}
   
     1. [Create](../../../iam/operations/authentication/manage-api-keys.md#create-api-key) an API key for the [service account](../../../iam/concepts/users/service-accounts.md) you are going to use for authentication.
     1. Create the `REGISTRY_USERNAME` and `REGISTRY_PASSWORD` environment variables:
   
         ```bash
         export REGISTRY_USERNAME="api_key"
         export REGISTRY_PASSWORD="<API_key>"
         ```
   
         Where:
   
         * `REGISTRY_USERNAME`: Authentication method.
         * `REGISTRY_PASSWORD`: Body of the previously created [API key](../../../iam/concepts/authorization/api-key.md).
   
     {% note info %}
   
     The API key maximum [lifetime](../../../iam/concepts/authorization/api-key.md#scoped-api-keys) is set manually when you create the key.
   
     {% endnote %}
   
   {% endlist %}
1. In the user’s root directory, create a file named `~/.pypirc` with the following content and specify the token in it:

    {% list tabs group=registry_auth %}

    - IAM token {#iam-token}

      ```text
      [distutils]
      index-servers =
          cloud-registry

      [cloud-registry]
      repository = https://registry.yandexcloud.net/pypi/<registry_ID>/legacy/
      username = iam
      password = <IAM_token>
      ```

    - API key {#api-key}

      ```text
      [distutils]
      index-servers =
          cloud-registry

      [cloud-registry]
      repository = https://registry.yandexcloud.net/pypi/<registry_ID>/legacy/
      username = api_key
      password = <API_key>
      ```

    {% endlist %}
