# Power BI Configuration

Mosaic must be authorised on your Power BI tenant to embed reports and execute DAX queries on behalf of your users.

There are three steps, in order:

1. [**Azure App Registration**](/mosaic/get-started/powerbi-configuration/azure-app-registration.md) — created automatically when you activate Mosaic; this page covers what was registered and how to verify
2. [**Power BI Admin Portal Configurations**](/mosaic/get-started/powerbi-configuration/powerbi-admin-portal.md) — enable the necessary tenant-level switches in the Power BI Admin Portal
3. [**Mosaic App Configurations**](/mosaic/get-started/powerbi-configuration/mosaic-app-configurations.md) — point Mosaic at your Power BI workspaces and curate the resource catalog

## Who runs these steps

You'll need:

* A user with the **Power BI Administrator** role (to change tenant settings)
* A user with **Microsoft Entra Application Administrator** rights (to verify the Mosaic enterprise application registration)
* A user with **Mosaic Tenant Admin** access (to curate the catalog inside Mosaic)

These are often three different people. Coordinate before you start.

## How long it takes

Plan to spend **\~30 minutes** the first time. Most of it is one-time setup that doesn't need to be repeated unless your Power BI capacity, tenant settings, or workspaces materially change.
