Azure Service Principal Skill

This skill creates and configures Azure Service Principals with workload identity federation for secure, passwordless authentication.

Overview

Creates an Entra ID App Registration and Service Principal configured for workload identity federation (no secrets). Grants Contributor role on resource groups and prepares for Cognitive Services User role assignment on AI Services resources.
