1. The “Orphaned Report” Trap
When a user is deleted from the organization, their owned reports don’t disappear, but they become unowned and may not be accessible. If a report uses the “Owner’s Credentials” for a data source, the dependent reports/dashboards will break immediately upon the user’s account suspension. You may refer here about what data will be deleted when user is deleted.
-
Tip: Before deletion, use the Looker Studio Asset Manager (available to Workspace Admins) to filter by the departing user and bulk-transfer ownership to a service account or a team lead. More details are here. You will see this option while deleting the user and select both check boxes under Looker Studio to transfer all reports and dependent data sources.
-
Trick: If you’ve already deleted the user, you have a 20-day window to restore the account in Google Admin Console to reclaim and transfer assets before they become permanently unmanageable. For more details on restore options refer here. Restore the recently deleted user, then try deleting again, this time make sure to transfer the assets as described in first step.
2. Decouple Data via Service Accounts
For BI Admins, the biggest headache is credential expiration. If a GCP Project Admin deletes a user who authorized a BigQuery connector, every dashboard downstream fails.
- The Pro Move: Shift all production data sources to Service Account credentials.
- How: Instead of “Owner’s Credentials,” use a JSON key or a service account identity to authorize the BigQuery/GA4 connection. This makes the workflow immune to individual staff turnover.
3. The Proactive “Offboarding Group”
Managing individual permissions is a scaling nightmare.
- The Strategy: Use Google Groups for Looker Studio permissions rather than individual emails.
- The Workflow: When a user leaves, you simply remove them from the “BI-Viewers” or “BI-Editors” Google Group. They lose access instantly, but the underlying asset structure remains intact because the Group still holds the permission.
4. Permission Hierarchy & Cleanup
It is vital to understand where the “kill switch” lies for different admin roles:
| Admin Role | Action Point | Impact |
|---|---|---|
| Google Workspace Admin | Admin Console User Deletion | Revokes app access; triggers 20-day asset recovery window. |
| GCP Project Admin | IAM & Admin Panel | Revokes access to underlying data (BigQuery, Cloud Storage). |
| Looker Studio Admin | Asset Manager | Transfers ownership of specific reports and data sources. |
5. Audit Logging for Compliance
IT Admins often need to prove that a revoked user no longer has eyes on sensitive data.
- Tip: Enable Looker Studio events in the Google Workspace Audit Logs. This allows you to filter by
User_IDand see exactly which reports they accessed or modified in their final 30 days. - Trick: Use the Looker Studio Pro “Team Workspaces” feature. Assets in a Team Workspace are owned by the organization, not the individual, which bypasses the “Orphaned Report” issue entirely during deletion.
