With the Centovacast control panel, you have an administrator password
and a source password. The administrator password is for logging into the control panel and admin areas of your server. The source password is for your DJ's to use purely to broadcast to the server (along with the hostname / port). You can change the source / administrator passwords from the 'Configure Server > Stream' area of your control panel. Make your source password different from your administrator password and give the source password to your DJ's. You can then change your source password to block out your DJ's if need be at a later date.
