-By default, the Databricks SDK for Python initially tries [Databricks token authentication](https://docs.databricks.com/dev-tools/api/latest/authentication.html) (`auth_type='pat'` argument).

+By default, the Databricks SDK for Python initially tries [Databricks token authentication](https://docs.databricks.com/dev-tools/api/latest/authentication.html) (`auth_type='pat'` argument). If the SDK is unsuccessful, it then tries Workload Identity Federation (WIF) based authentication with support for GitHub Actions (`auth_type: "github-oidc"`) and Azure DevOps Pipelines (`auth_type: "azure-devops-oidc"`).
 
 - For Databricks token authentication, you must provide `host` and `token`; or their environment variable or `.databrickscfg` file field equivalents.
 - For Databricks OIDC authentication, you must provide the `host`, `client_id` and `token_audience` _(optional)_ either directly, through the corresponding environment variables, or in your `.databrickscfg` configuration file.
+- For Azure DevOps OIDC authentication, the `token_audience` is irrelevant as the audience is always set to `api://AzureADTokenExchange`. Also, the `System.AccessToken` pipeline variable required for OIDC request must be exposed as the `SYSTEM_ACCESSTOKEN` environment variable, following [Pipeline variables](https://learn.microsoft.com/en-us/azure/devops/pipelines/build/variables?view=azure-devops&tabs=yaml#systemaccesstoken)
