 > [!WARNING]
 > By default, the output of Azure CLI commands is printed to the stdout stream. Without redirecting the stdout stream, contents in it will be stored in the build log of the action. Configure Azure CLI to _not_ show output in the console screen or print in the log by setting the environment variable `AZURE_CORE_OUTPUT` to `none`. If you need the output of a specific command, override the default setting using the argument `--output` with your format of choice. For more information on output options with the Azure CLI, see [Format output](https://learn.microsoft.com/cli/azure/format-output-azure-cli).

 > Avoid using managed identity login on self-hosted runners in public repositories. Managed identities enable secure authentication with Azure resources and obtain Azure AD tokens without the need for explicit credential management. Any user can open pull requests against your repository and access your self-hosted runners without credentials.
