### Recommended App Registration per Azure App

For most customers, we recommend creating a **separate Azure App Registration for each Blockbrain agent or capability** (e.g. one for SharePoint, one for Outlook, one for OneDrive).

This approach gives you:

* **Least privilege:** Each App Registration only holds the Microsoft Graph scopes it actually needs, so no agent is over-permissioned.
* **Separation of concerns:** A misconfigured or unused agent cannot accidentally affect another agent's access.
* **Easy secret rotation and revocation:** You can rotate or revoke the client secret for a single capability without disrupting the others.
* **Cleaner audit trail:** Entra ID sign-in and audit logs are scoped per App Registration, which makes incident review and access reviews simpler.

{% hint style="warning" %}
While this documentation provides detailed steps we recommend a brief setup call with our expert team to ensure a smooth implementation.

Though not mandatory, experience has shown that a 15-20 minute setup call can significantly accelerate your integration and help avoid potential configuration issues.

To schedule a setup call please contact your Key Account Manager.
