Define the **Element Type** properties shown below, so that Kron PAM can identify the OS of the discovered instances:

1. Navigate to **Devices > Element Type.**
2. Create a new element type and add** a Google Cloud** tag.
3. Click the **Next **button of the related element type.
4. Fill in the **Gcp Element Type Pattern**, **Gcp Access Protocol**, and **Gcp SSH Username** properties.

| **Parameter Name**           | **Parameter Value**                                                                                                                                                           |

| **Gcp Access Protocol**      | Mandatory.<br />This property is used to determine the default access method for the discovered instances                                                                     |
| **Gcp Element Type Pattern** | Mandatory.<br />The pattern can be defined as multiple in one element.<br />This pattern is checked against the “Image” description of the instance to determine the OS type. |
| **Gcp SSH Username**         | Mandatory for logging in. Not required for device import.<br />This username is used as the default login credential.                                                         |
| <br />**Gcp Port Number**    | Optional.<br />Devices are imported with the defined port number value. If this value is not set, a default port number is used, such as 22 for SSH.                          |

:::hint{type="info"}
Defining a new Element Type for each OS type is required, for Kron PAM to autodetect devices.&#x20;
Ex: CentOS Linux, Ubuntu Linux, etc.
