Browser fingerprinting is a powerful tracking technique that collects a unique "snapshot" of your device based on its specific configuration. Unlike cookies, which are files stored on your computer, fingerprinting gathers data 📊 that your browser naturally shares with websites, such as your screen resolution, installed fonts, operating system, and even the way your hardware renders graphics.

Because the combination of these settings is so specific, it can create a highly accurate digital ID that identifies you across different websites, even if you use a VPN or clear your browsing history. It is often used for fraud prevention and security 🔐 but more commonly for invasive advertising and persistent user tracking without consent.
