# Local Administrator Password Solution CSP

The Local Administrator Password Solution (LAPS) configuration service provider (CSP) is used by the enterprise to manage back up of local administrator account passwords. This CSP was added in Windows 11 as of version 25145.

> [!IMPORTANT]
> Windows LAPS currently is available only in [Windows 11 Insider Preview Build 25145 and later](/windows-insider/flight-hub/#active-development-builds-of-windows-11). Support for the Windows LAPS Azure Active Directory scenario is currently in private preview, and limited to a small number of customers who have a direct engagement with engineering. Once public preview is declared in 2023, all customers will be able to evaluate this AAD scenario.

> [!TIP]
> This article covers the specific technical details of the LAPS CSP.  For more information about the scenarios in which the LAPS CSP would be used, see [Windows Local Administrator Password Solution](/windows-server/identity/laps/laps).

The following example shows the LAPS CSP in tree format.

```xml
./Device/Vendor/MSFT
LAPS
----Policies
--------BackupDirectory
--------PasswordAgeDays
--------PasswordLength
--------PasswordComplexity
--------PasswordExpirationProtectionEnabled
--------AdministratorAccountName
--------ADPasswordEncryptionEnabled
--------ADPasswordEncryptionPrincipal
--------ADEncryptedPasswordHistorySize
--------PostAuthenticationResetDelay
--------PostAuthenticationActions
----Actions
--------ResetPassword
--------ResetPasswordStatus
```

The LAPS CSP can be used to manage devices that are either joined to Azure AD or joined to both Azure AD and Active Directory (hybrid-joined). The LAPS CSP manages a mix of AAD-only and AD-only settings. The AD-only settings are only applicable for hybrid-joined devices, and then only when BackupDirectory is set to 2.

|Setting name|Azure-joined|Hybrid-joined|
|---|---|---|
|BackupDirectory|Yes|Yes
|PasswordAgeDays|Yes|Yes
|PasswordLength|Yes|Yes|
|PasswordComplexity|Yes|Yes|
|PasswordExpirationProtectionEnabled|No|Yes|
|AdministratorAccountName|Yes|Yes|
|ADPasswordEncryptionEnabled|No|Yes|
|ADPasswordEncryptionPrincipal|No|Yes|
|ADEncryptedPasswordHistorySize|No|Yes|
|PostAuthenticationResetDelay|Yes|Yes|
|PostAuthenticationActions|Yes|Yes|
|ResetPassword|Yes|Yes|
|ResetPasswordStatus|Yes|Yes|

> [!IMPORTANT]
> Windows supports a LAPS Group Policy Object that is entirely separate from the LAPS CSP. Many of the various settings are common across both the LAPS GPO and CSP (GPO does not support any of the Action-related settings). As long as at least one LAPS setting is configured via CSP, any GPO-configured settings will be ignored. Also see [Configure policy settings for Windows LAPS](/windows-server/identity/laps/laps-management-policy-settings).

|5|Reset password and reboot|The managed account password will be reset and the managed device will be immediately rebooted.|

If not specified, this setting will default to 3.

> [!IMPORTANT]
> The allowed post-authentication actions are intended to help limit the amount of time that a LAPS password may be used before being reset. Logging off the managed account - or rebooting the device - are options to help ensure this. Abrupt termination of logon sessions, or rebooting the device, may result in data loss.

> [!IMPORTANT]
> From a security perspective, a malicious user who acquires administrative privileges on a device using a valid LAPS password does have the ultimate ability to prevent or circumvent these mechanisms.
