To use a Service Account instead of OAuth2 token flow, enter the pathto your Service Account credentials at the service_account_fileprompt during rclone config and rclone won't use the browser basedauthentication flow. If you'd rather stuff the contents of thecredentials file into the rclone config file, you can setservice_account_credentials with the actual contents of the fileinstead, or set the equivalent environment variable.
