Single Connect allows users to establish an SSH connection with a valid passphrase. To use an SSH Key, the **globalUsername** and **globalSshKeyPassphrase** need to be defined for the Device Group:

1. Navigate to **Device Management **> **Device Groups**.
2. Right-click the device group and select the **Show Properties** option.
3. Set the privileged target device username as **globalUsername**.
4. Set the SSH Key as **globalSshKeyPassphrase**.
