In Microsoft’s Security, Compliance, and Identity guidance, Azure AD Privileged Identity Management (PIM) is the service used to manage, control, and monitor access to important resources in Azure and Microsoft 365. The documentation explains that PIM enables “just-in-time” and “time-bound” activation of privileged roles, requiring users to elevate only when needed and for a limited duration. PIM policies can require approval before a role is activated, enforce multifactor authentication, capture business justification, send notifications, and maintain detailed auditing and access review records. These controls are designed to reduce the risk associated with standing administrative privileges by ensuring that elevation is temporary, approved, and tracked.
By contrast, Windows Hello for Business provides strong, device-bound authentication; Azure AD Identity Protection focuses on detecting and remediating risky sign-ins and users; and Azure AD Access Reviews periodically reattest existing assignments but do not provide the on-demand, approval-based, time-limited activation of roles. Therefore, when the requirement is approval-based, time-bound role activation, Microsoft’s prescribed capability is Azure AD PIM, which delivers just-in-time elevation with approvers, duration limits, and audit/logging to support least privilege and Zero Trust operational practices.
