Browser Fingerprint Test
This page reads the same signals any website can read from your browser — no login, nothing stored. It shows how identifiable you are, and why every account you open on this device looks like the same person.

What is a browser fingerprint?
A browser fingerprint is the combination of dozens of small details — your Canvas and WebGL rendering, fonts, timezone, screen size, hardware — that together identify your device almost uniquely, even without cookies. This is how e-commerce and ad platforms link multiple accounts back to one person and ban them, even if you use a different proxy or clear cookies.
Fingerprint test — FAQ
What does this browser fingerprint test check?
It reads your user agent, platform, languages, timezone, screen and device properties, plus your Canvas and WebGL rendering signatures — the same signals a website's anti-fraud system reads. It combines them into a single signature so you can see how identifiable your browser is.
Does clearing cookies or using a VPN change my fingerprint?
No. Cookies and IP address are separate from the fingerprint. Clearing cookies or switching VPN leaves your Canvas, WebGL, fonts and hardware signals identical, so accounts can still be linked. Only changing the fingerprint itself — what an antidetect browser does per environment — actually separates them.
How does Nox Core change my fingerprint?
Nox Core assigns each isolated environment its own unique Canvas, WebGL, Audio and Navigator fingerprint plus its own SOCKS5 proxy, so every account runs on what looks like a distinct real device. You can verify it by opening two Nox Core environments and re-running this test in each.
