If you ever forget the root (Linux) or the Administrator (Windows) password to your VPS then you can reset it through your Cloud VPS Management Panel.
Simply click the settings tab, then Change Password.
Enter your New Password, then Retype New Password. And press the below, blue confirmation button.
You will then need to Stop, Power Off and Start the VPS to apply the changes. Please ensure these steps are followed as password changes are written to the server in the Power Off stage.
