An overpowered JavaScript browser fingerprinting library
OPFS is a browser fingerprinting library for creating persistent, unique and long-lasting digital fingerprints without depending on ever-changing variables such as the user agent string commonly used in other browser fingerprinting libraries. As such, the fingerprint does not change most of the time when a user upgrades their browser to the current version. OPFS uses some novel methods not well known before the publishing of this repo that allow the creation of a likely completely unique device fingerprint in Google Chrome, Microsoft Edge and other Chromium-based browsers. This also applies to Firefox as long as it is not resisting fingerprinting. The library is able to detect and mitigate the effects of browser-based anti-fingerprinting technologies introduced to certain browsers in the past few years with the release of Brave Browser and Safari 13.
