Browser Fingerprint
The combination of browser and device attributes that together identify a specific browser instance.
A fingerprint is assembled from signals such as user agent, screen resolution, installed fonts, timezone, language, and how the device renders canvas and WebGL content. Individually these are unremarkable; combined, they are often unique enough to re-identify a browser even without cookies. Anti-detect browsers exist to give each profile a distinct, internally consistent fingerprint.
In practice
- Two accounts flagged as linked despite different IPs, because both reported an identical canvas hash
