Why are you so unwilling to read anything on that page except that specific paragraph. The next paragraph says:

> Preferences cookies — Also known as “functionality cookies,” these cookies allow a website to remember choices you have made in the past, like what language you prefer, what region you would like weather reports for, or what your user name and password are so you can automatically log in.

and further down the page a little bit:

> Receive users’ consent before you use any cookies except strictly necessary cookies.

I sincerely hope that nobody reading this thread follows any of your terribly incorrect advice.
