What is a browser fingerprint?

A browser fingerprint is a collection of attributes that uniquely identify your browser across sessions. Even without cookies, websites can combine your user-agent, screen resolution, timezone, language, and dozens of other attributes to create a unique identifier. Studies show that browser fingerprints can identify individual users with over 99% accuracy.

How to protect your fingerprint

Anti-detect browsers like ProxyNest create a unique fingerprint for each browser session. Each session gets its own user-agent, platform, language, timezone, and screen resolution — making it appear as a different device. Combined with a different proxy IP, each session is fully unlinked from your real identity. Learn more about ProxyNest →
