BigQuery customers have the option of using OAuth for BigQuery connections. (The other option is service accounts). These connections are "directly integrated" with GCP Identity and Access Management (IAM). This provides user-level authentication (OAuth) and authorization (IAM). Every query is run as if that user was running the same SQL when directly logged in to the BQ console.
