Scraping content behind login
There is no any futher steps needed to scrape content behind login.
You log in the target website without your account, and then start NDS to define or execute recipes. If only the browser keeps you logged in, NDS can follow your instructions to scrape the content behind login. Here NDS will not touch your account and cookie. The cookie is managed by browser so the scraping activity itself will update your cookie status to avoid timeout.
