# DeviceLock CSP

This policy is deprecated. Use [Policy CSP](policy-configuration-service-provider.md) instead.

<!-- 12.16.2021 mandia: Commenting out, as this CSP is specific to Windows Phone 8.1.

The DeviceLock configuration service provider is used by the enterprise management server to configure device lock related policies. This configuration service provider is supported by an enterprise management server.

> [!Note]
> For Windows 10 devices, use [Policy CSP](policy-configuration-service-provider.md) for various device lock settings. You can continue to use DeviceLock CSP for Windows Phone 8.1 GDR devices. The DeviceLock CSP will be deprecated some time in the future.

 

The DevicePasswordEnabled setting must be set to 0 (device password is enabled) for the following settings to take effect:

-   AllowSimpleDevicePassword
-   MinDevicePasswordLength
-   AlphanumericDevicePasswordRequired
-   MaxDevicePasswordFailedAttempts
-   MaxInactivityTimeDeviceLock
-   MinDevicePasswordComplexCharacters

The following information shows the DeviceLock configuration service provider in tree format.

```console
./Vendor/MSFT
DeviceLock
--------Provider
----------ProviderID
-------------DevicePasswordEnabled
-------------AllowSimpleDevicePassword
-------------MinDevicePasswordLength
-------------AlphanumericDevicePasswordRequired
-------------MaxDevicePasswordFailedAttempts
-------------DevicePasswordExpiration
-------------DevicePasswordHistory
-------------MaxInactivityTimeDeviceLock
-------------MinDevicePasswordComplexCharacters
----------DeviceValue
-------------DevicePasswordEnabled
-------------AllowSimpleDevicePassword
-------------MinDevicePasswordLength
-------------AlphanumericDevicePasswordRequired
-------------MaxDevicePasswordFailedAttempts
-------------DevicePasswordExpiration
-------------DevicePasswordHistory
-------------MaxInactivityTimeDeviceLock
-------------MinDevicePasswordComplexCharacters
```

<a href="" id="provider"></a>**Provider**  
Required. An interior node to group all policy providers. Scope is permanent. Supported operation is Get.

<a href="" id="---------------providerid"></a> ***ProviderID***  
Optional. The node that contains the configured management server's ProviderID. Exchange ActiveSync policies set by Exchange are saved by the Sync client separately. Scope is dynamic. The following operations are supported:

-   **Add** - Add the management account to the configuration service provider tree.
-   **Delete** - Delete all policies set by this account. This command could be used in enterprise unenrollment for removing policy values set by the enterprise management server.
-   **Get** - Return all policies set by the management server.

> [!NOTE]
> The value cannot be changed after it's added. The **Replace** command isn't supported.

 

<a href="" id="providerid-devicepasswordenabled"></a>***ProviderID*/DevicePasswordEnabled**  
Optional. An integer value that specifies whether device lock is enabled. Possible values include:

-   0 - Device lock is enabled.
-   1 (default) - Device lock not enabled.

The scope is dynamic.

Supported operations are Get, Add, and Replace.

<a href="" id="providerid-allowsimpledevicepassword"></a>***ProviderID*/AllowSimpleDevicePassword**  
Optional. An integer value that specifies whether simple passwords, such as "1111" or "1234", are allowed. Possible values include:

-   0 - Not allowed.
-   1 (default) - Allowed.

Invalid values are treated as a configuration failure. The scope is dynamic.

Supported operations are Get, Add, and Replace.

<a href="" id="providerid-mindevicepasswordlength"></a>***ProviderID*/MinDevicePasswordLength**  
Optional. An integer value that specifies the minimum number of characters required in the PIN. Valid values are 4 to 18 inclusive. The default value is 4. Invalid values are treated as a configuration failure. The scope is dynamic.

Supported operations are Get, Add, and Replace.

<a href="" id="providerid-alphanumericdevicepasswordrequired"></a>***ProviderID*/AlphanumericDevicePasswordRequired**  
Optional. An integer value that specifies the complexity of the password or PIN allowed.

Possible values include:

-   0 - Alphanumeric password required
-   1 - Users can choose a numeric or alphanumeric password
-   2 - Users can choose no password, numeric password, or alphanumeric password

Invalid values are treated as a configuration failure. The scope is dynamic.

Supported operations are Get, Add, and Replace.

<a href="" id="providerid-devicepasswordexpiration"></a>***ProviderID*/DevicePasswordExpiration**  
Deprecated in Windows 10.

<a href="" id="providerid-devicepasswordhistory"></a>***ProviderID*/DevicePasswordHistory**  
Deprecated in Windows 10.

<a href="" id="providerid-maxdevicepasswordfailedattempts"></a>***ProviderID*/MaxDevicePasswordFailedAttempts**  
Optional. An integer value that specifies the number of authentication failures allowed before the device will be wiped. Valid values are 0 to 999. The default value is 0, which indicates the device won't be wiped, whatever the number of authentication failures.

Invalid values are treated as a configuration failure. The scope is dynamic.

Supported operations are Get, Add, and Replace.

<a href="" id="providerid-maxinactivitytimedevicelock"></a>***ProviderID*/MaxInactivityTimeDeviceLock**  
Optional. An integer value that specifies the amount of time (in minutes) that the device can remain idle before it's password locked. Valid values are 0 to 999. A value of 0 indicates no time-out is specified. In this case, the maximum screen time-out allowed by the UI applies.

Invalid values are treated as a configuration failure. The scope is dynamic.

Supported operations are Get, Add, and Replace.

<a href="" id="providerid-mindevicepasswordcomplexcharacters"></a>***ProviderID*/MinDevicePasswordComplexCharacters**  
Optional. An integer value that specifies the number of complex element types (uppercase and lowercase letters, numbers, and punctuation) required for a strong password. Valid values are 1 to 3 for Windows client. The default value is 1.

Invalid values are treated as a configuration failure. The scope is dynamic.

Supported operations are Get, Add, and Replace.

<a href="" id="devicevalue"></a>**DeviceValue**  
Required. A permanent node that groups the policy values applied to the device. The server can query this node to discover what policy values are applied to the device. The scope is permanent.

Supported operation is Get.

<a href="" id="devicevalue-devicepasswordenable-----mindevicepasswordcomplexcharacters"></a>**DeviceValue/DevicePasswordEnable, …, MinDevicePasswordComplexCharacters**  
Required. This node has the same set of policy nodes as the **ProviderID** node. All nodes under **DeviceValue** are read-only permanent nodes. Each node represents the current device lock policy. For detailed descriptions of each policy, see the ***ProviderID*** subnode descriptions.

## Remarks


All node values under the **ProviderID** interior node represent the policy values set by the management server.

-   An **Add** or **Replace** command on those nodes returns success in the following cases:

    -   The value is applied to the device.

    -   The value isn't applied to the device because the device has a more secure value set already.

        From a security perspective, the device complies with the policy request that's at least as secure as the one requested.

-   A **Get** command on those nodes returns the value the server pushes down to the device.

-   If a **Replace** command fails, the node value is set back to the value that was to be replaced.

-   If an **Add** command fails, the node isn't created.

The value applied to the device can be queried via the nodes under the **DeviceValue** interior node.
