To create a Trusted Devices list, navigate to **Policies -> Trusted Devices -> Create**.

![Deploy Policy](https://www.manageengine.com/products/desktop-central/help/images/dc-td2.png)

1. **Policy name:**  
   Enter a name for the device list to be created.
2. **Description (optional):**  
   Add a description to clarify the device list's purpose.

There are three ways to create a device list:

1. [Add Existing Devices](#add-existing-devices)  
2. [Add New Devices](#add-new-devices)  
3. [Import files](#import-files)

## Add Existing Devices

Add Existing Devices allows the admin to select devices already recognized within the network, simplifying the process of building a trusted device list.

1. Select the device type.
2. From the list of recognized devices, click on **"Add"** to include the device in the device list.
3. Click on **"Save"** to confirm and store the device list.

## Add New Devices

1. Select the device type.
2. Choose a method for adding a device: you can add a device using its ID and serial number, or by specifying the device path.
3. For **"IDs and Serial Number"**: Enter the Vendor ID, Product ID, and Serial Number.
4. For **"Device Path"**: Enter the Parent device instance path and the device instance path.
5. Enter a custom name for the new device.
6. Click **"Add"** to include the device in the device list and then click **"Save"**.

## Add Trusted Devices using Wildcard Pattern

Instead of specifying individual devices, use a common wildcard pattern to trust an entire group of similar devices.

![Wild Card pattern](https://www.manageengine.com/products/desktop-central/help/images/dc-td6.png)

To create a wildcard pattern:

1. Navigate to **Policies -> Trusted Devices -> Create New -> Add New Devices**.
2. Choose **ID's and Serial Number** method.
3. Provide the Product and Vendor ID, and then specify the wildcard pattern `"*"` and `"?"` for Serial Number and click **"Add"**.

**Note:**  
Use `?` to replace a single variable character.  
Use `*` to replace more than one variable character.

## Import files

![CSV](https://www.manageengine.com/products/desktop-central/help/images/dc-td5.png)

1. Select the device type.
2. Select the CSV file containing trusted devices data and click **"Add"**.  
   CSV files can be uploaded in two supported formats. Refer to the format examples provided [here](https://www.manageengine.com/products/desktop-central/help/device-control/csv-format.html).
3. Once devices are added to the list, click **Save** to confirm and store the changes.
