LAPS for Azure Arc: Local Admin Password Security Across Hybrid—at Scale

This article discusses LAPS for Azure Arc, a capability that enhances local administrator password security across hybrid IT environments. It explains how Azure Arc integrates with Windows LAPS to generate unique, random passwords per machine, enforce rotation schedules, and store credentials securely in Microsoft Entra ID or Active Directory. Using Azure Policy and Machine Configuration, organizations can audit and enforce LAPS settings at scale across Azure VMs and Arc-enabled servers on-premises, edge, or other clouds. The article covers audit-first and enforce modes, default security configurations aligned with NIST and CIS guidance, and tuning options like password length and rotation frequency. It provides a technical guide for IT professionals managing hybrid infrastructure security.
