Windows LAPS

Also known as: LAPS, Local Administrator Password Solution, Microsoft LAPS

Windows LAPS (Local Administrator Password Solution) is a built-in Windows feature that automatically gives each computer's local administrator account a unique, random password, changes it regularly, and stores it securely in Microsoft Entra ID or Active Directory.

IT staff can look up a password when needed. It stops a common attack where criminals crack one shared local admin password and use it to move across every PC. While LAPS is free and effective, many small businesses still use the same local admin password on every machine.

Windows LAPS, explained at three levels

At home

LAPS is like giving every hotel room its own unique key that changes regularly, instead of using one master key that opens every room.

At work

LAPS stops an attacker who gets into one PC from using the same admin password on all the others.

Real-world examples

At home

Fatima's brother uses the same admin password on every family computer. She suggested unique passwords for each, the same idea behind LAPS.

At work

Thomas manages a Gatineau accounting firm's 40 PCs. He enabled Windows LAPS through Intune, replacing a single local admin password every technician knew.

For analysts

In security assessments, I'd check whether local admin passwords are shared. It's a quick finding with a free, well-supported fix.

History & origin

For years, organizations often set the same local administrator password on every PC. In 2014, Microsoft fixed a flaw where passwords stored through Group Policy Preferences could be easily decrypted, leaving many companies without a safe way to manage local passwords. Microsoft released the original LAPS as a free add-on in 2015. In April 2023, Microsoft built a new version, Windows LAPS, directly into Windows 10, Windows 11, and Windows Server, adding support for cloud-based Entra ID, encrypted password storage, and automatic rotation after use. In my view, Windows LAPS is one of the easiest security wins in a Windows environment.
