Create a service account and configure authentication before running the collector.

## Before you begin

Role required: admin

## About this task

The collector connects to BigQuery using a service account associated with your project.

## Procedure

1. Create a [service account](https://cloud.google.com/iam/docs/creating-managing-service-accounts).  
   Assign the following roles to the service account:
   * [BigQuery Data Viewer](https://cloud.google.com/bigquery/docs/access-control#bigquery.dataViewer)
   * [BigQuery User](https://cloud.google.com/bigquery/docs/access-control#bigquery.user)
2. Create a key for the service account and download the JSON key file.  
   See the [Creating and managing service account keys](https://cloud.google.com/iam/docs/creating-managing-service-account-keys) documentation for details.
3. Place the key file on the machine where you plan to run the collector.  
   You need this file when configuring the collector.

## What to do next

See the [Google Cloud Platform predefined roles and permissions documentation](https://cloud.google.com/iam/docs/understanding-roles#predefined_roles) for additional information.
