+> [!Important]
+> The DeviceLock CSP utilizes the [Exchange ActiveSync Policy Engine](/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/dn282287(v=ws.11)). When password length and complexity rules are applied, all the local user and administrator accounts are marked to change their password at the next sign in to ensure complexity requirements are met. For additional information, see [Password length and complexity supported by account types](/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/dn282287(v=ws.11)#password-length-and-complexity-supported-by-account-types)).
