A third-party cookie is a cookie that is set by a website other than the one you are visiting. This means that the website you are visiting is using a third-party service, such as an advertisement or analytics service, that is setting its own cookies on your device.
Third-party cookies are used for a variety of purposes, including tracking your browsing activity and targeting advertisements to you. Some people have concerns about third-party cookies because they may be used to gather information about their online activities without their knowledge or consent.
In recent years, there have been efforts to limit the use of third-party cookies in order to protect users’ privacy. For example, some web browsers now block third-party cookies by default or offer users the option to block them. Additionally, some websites and online services have begun to use alternative technologies, such as “first-party cookies” or browser fingerprinting, to track users and gather data.
