A cookie is a small piece of text sent to your browser by a website you visit. It helps the site remember information about your visit, which can make it easier to visit the site again and make the site more useful to you. Data stored in a cookie is created by the server you connect to. This data is assigned an ID unique to you and your computer. When the cookie is exchanged between your computer and the network server, the server reads the ID and knows what information to specifically serve to you.
Functionality. Cookies used for functionality allow users to interact with a service or site to access features that are fundamental to that service. Things considered fundamental to the service include preferences like product optimizations that help maintain and improve a service and maintaining information relating to a user’s session.
Some cookies are used to maintain a user’s preference during a specific browsing session. For example ‘t_consent’ is used to remember user preference. This cookie lasts for as long as the user keeps their browser open.
Security. These cookies limit the scope of the cookie to "secure" channels. When a cookie has the Secure attribute, it will be included only if the request is transmitted over a secure channel. Cookies used for security authenticate users, prevent fraud, and protect users as they interact with a service.
Analytics. Cookies help collect data that allows services to understand how users interact with a particular service. These insights allow services both to improve content and to build better features that improve the user’s experience.
