Register an Azure Active Directory Security Principal – PowerShell

An Azure service principal is a security identity used by applications, services, and automation tools to access designated Azure resources. The service principal is a ‘user identity’ (username and password) with an assigned role/permissions in Azure Active Directory (AAD).
