Branded key or whitelabel difference

By purchasing the reseller packages you will have whitelabel keys ... or keys that do not have the upgrader mark at the beginning, for example: XXXX-XXXX-XXXX-XXXX
Unlike the single keys that are generated with an initial brand, called branded key: UPGRADER-XXXX-XXXX-XXXX

So if you are interested in reselling spotify, using whitelabel keys, you will not allow your customers to find our site.
