Workspace Security

Hi DKHUghes55,

Yes, it is possible to identify which workspaces a user or security group has access to, but this cannot be done directly in Power BI Desktop. There are two main approaches:

Option 1 – Power BI Service Admin Portal

1. Access the Admin Portal.
2. Navigate to Workspaces.
3. Export the complete list of workspaces and their associated users or groups.
   • Use the Export to CSV feature for further analysis.

• This returns all workspaces.
• For each workspace, retrieve the members:

  GET https://api.powerbi.com/v1.0/myorg/groups/{groupId}/users

Combine the results to obtain a complete list of workspaces per user or group.

• Register an application in Azure Active Directory.
• Grant permissions to the Power BI API.
• Authenticate using OAuth2.

Hi DKHUghes55 ,

Thank you for reaching out to Microsoft Fabric Community.

Thank you Zanqueta for the prompt response.

Yes, you can identify which workspaces a user or group has access to, but a few clarifications are important:
The Admin Portal does not provide a direct export of users/groups per workspace or a list of workspaces for a specific user-you can only check access one workspace at a time.Power BI also doesn’t offer a single API that returns "workspaces for User X"; you need to list all workspaces and then check members for each.Tenant-wide results are only available if you are a Power BI Admin or a service principal with Admin permissions-otherwise the API shows only workspaces you can access.For admins, PowerShell is often the easiest option: Get-PowerBIWorkspace -All ,Get-PowerBIWorkspaceUser.API and PowerShell output will include users, security groups, M365 groups, and service principals.
