In the world of web scraping, multi-account management, and online privacy, the concept of a browser fingerprint has become a critical factor. While using a proxy server is the first step toward anonymity, it is no longer enough. Sophisticated websites and social networks can still identify you even if you change your IP address.
This guide will explain what a browser fingerprint is, how tools like BrowserScan can help you verify your anonymity, and why combining this verification with high-quality Nstproxy Residential Proxies is the only way to ensure your online identity remains unique and untraceable.
What Is a Browser Fingerprint?
A browser fingerprint is a unique online identifier created by collecting a vast array of data points exposed by your web browser and operating system. While deleting cookies and changing your IP address (via a proxy) can hide your location, your fingerprint remains constant.
Studies show that between 80-90% of web browsers have a unique fingerprint [1]. This means that social networks can easily link multiple accounts to the same user, even if each account uses a different proxy IP.
Data points that contribute to your unique fingerprint include:

- User-Agent String
- Screen Resolution and Color Depth
- Canvas and WebGL Fingerprint Data
- Hardware Details (CPU cores, graphics card)
- Browser Extensions and Ad-Blockers
