When you use the Internet, websites track your activity by storing data on your computer. They can do this by connecting to various services that use a device identifier known as a browser fingerprint. Your computer collects information about what you view and how you interact with websites to create your unique browser fingerprint.

For instance, if you use the Internet to watch a video on YouTube, the website will collect information about your browser and device, and combine that with your YouTube login to create your unique browser fingerprint. The fingerprint is then used to track you as you move from website to website.

In addition to cookies and other tracking technologies that websites use to track you, a number of websites also use fingerprinting techniques to improve their user experience. These techniques are used by websites such as Google Maps, Facebook, and Google Analytics.

These techniques are less effective than cookies because they collect less information. As a result, you can use them to create a unique browser fingerprint that will allow a website to track you without using cookies.
