# Prerequisites

### **Identity Providers**

HYBR supports two different authentication Identity providers to integrate on it. That is, Microsoft Entra ID & Active Directory Federation Service (ADFS). It allows users to authenticate HYBR Admin and Tenant Portals.

Please prepare Pre-requisites based on the Identity provider you are going to use (Microsoft Entra ID or ADFS).
