1.) Login to your client area & select the server where you would like to reset your password.
2.) Click on "Change Password".
3.) Insert the new password (Please make sure you do choose a strong password consisting of lower and upper case, numbers and symbols) Otherwise Windows may not accept it and you won't gain access. It also protects you from hackers.
4.) The last thing you have to do is to 'Restart' the VPS in order the changes happen. This is very important otherwise the password won't reset. Please click on the 'Restart' button. (Turning off and turning on will not work).
5.) You're done!
