There are different ways to connect to a device via Kron PAM. One of them is to define the username and password of the Linux/Windows server. Global usernames and passwords are local user credentials already used for the Linux/Windows device. Admin users can define these credentials in Kron PAM.

The perks of this method are as below:

- Kron PAM’s privileged users won’t know the server’s password and can only reach the server over Kron PAM.
- It prevents password sharing and keeps all the logs of connected users.

`To define global username and password for the respective server, follow the steps below:`

1. Navigate to **Device Management** > **Device Groups**.
2. Go to the **Device Groups **tab.
3. Right-click on the device group containing the Linux/Windows Server and select** Show Properties**.
4. Select **globalUsername** from **the Property Key** section. Enter the username of the Linux/Windows Server User into the Value section and save
5. Select globalPassword from the Property Key section. Enter the password of the Linux/Windows Server User into the **Value** section and **Save**.
