 [Microsoft Entra ID](https://learn.microsoft.com/en-us/entra/identity/) is a cloud-based identity and access management service that can be used for authentication in the Telerik Report Server for .NET. 
 
 In this article, we will explain how to set up and enable the Microsoft Entra ID authentication for the users of the Telerik Report Server for .NET. Besides the enhanced authentication security, this approach also improves the user experience, because the users who are already registered in Microsoft Entra will be able to log into Report Server Manager UI without entering their login credentials each time.
