What are cookies?

Cookies are small pieces of data sent from a website and stored in the user’s web browser while the user is browsing. Cookies were designed to be a reliable mechanism for websites to remember stateful information (such as items added in the shopping cart in an online store) or to record the user’s browsing activity (including clicking particular buttons, logging in, or recording which pages were visited in the past). They can also be used to remember arbitrary pieces of information that the user previously entered into form fields such as names, addresses, passwords, and credit card numbers.

Other kinds of cookies perform essential functions in the modern web. Perhaps most importantly, authentication cookies are the most common method used by web servers to know whether the user is logged in or not, and which account they are logged in with. Without such a mechanism, the site would not know whether to send a page containing sensitive information, or require the user to authenticate themselves by logging in.

The tracking cookies, and especially third-party tracking cookies, are commonly used as ways to compile long-term records of individuals’ browsing histories – a potential privacy concern. European law requires all websites targeting European Union member states gain “informed consent” from users before storing non-essential cookies on their device.
