Your purchase of any "Pro" product comes with a License Key. A Product License Key can be entered into the Automatic Upgrade panel in supporting software applications (i.e. in the pro version of themes/plugins that allow for automatic upgrades). If the automatic upgrader asks for your username/password @ websharks-inc.com, you can choose to use your Product License Key instead of your account password. The use of a License Key is recommended for improved security.
