Technically, super cookies are not cookies. At least not the HTTP cookies most of us are familiar with which are placed in our browsers by websites in order to store and access information about us. The HTTP cookies we’re familiar with provide full visibility and transparency, they can be edited by the user, and of course, deleted.
The super cookie can contain a very large scope of data (up to 100 KB) concerning a user’s personal internet browsing. In fact, the super cookie can include data obtained from the user’s traditional HTTP cookies, including sensitive information like passwords, cached images, and more.
