Authentication ensures that only the authorized users are allowed to connect to a Google BigQuery instance.

The Google BigQuery driver supports the following methods of authentication:

  • OAuth 2.0 authentication allows the user to authenticate to a Google BigQuery instance without having to specify user ID and password.
  • Service account authentication. It allows the users to authenticate to a Google BigQuery instance using a service account, which is a type of Google account that represents an application instead of an individual end user.
