Question 1

What is a browser fingerprint?

Accepted Answer

A browser fingerprint is a unique identifier created by combining dozens of technical attributes your browser exposes - screen resolution, installed fonts, graphics card details, timezone, language settings, and more. Even without cookies, websites can use this combination to recognize and track you across sessions with surprising accuracy.

Question 2

Can I prevent browser fingerprinting?

Accepted Answer

Complete prevention is difficult, but you can reduce your uniqueness. Use the Tor Browser or Firefox with privacy.resistFingerprinting enabled, which normalizes many values. Privacy-focused browsers like Brave also add noise to canvas and audio fingerprints. VPNs do not help with fingerprinting since it is based on browser properties, not your IP address.

Question 3

What is a canvas fingerprint?

Accepted Answer

A canvas fingerprint works by drawing hidden text and shapes using the HTML5 Canvas API. Because every device renders graphics slightly differently due to differences in GPU, drivers, fonts, and OS rendering engines, the resulting pixel data produces a near-unique hash. This hash persists across browser sessions and cannot be blocked by clearing cookies or using private browsing mode.
