FingerprintJS is a free and open-source JavaScript library that can be used to generate a unique identifier for each user. This identifier is based on a variety of factors, including the user's browser, operating system, and hardware. FingerprintJS is used by a variety of websites and applications to track users and prevent fraud. It is also used by researchers to study user behavior.

FingerprintJS is a powerful tool that can be used to improve the security and usability of your website or application. It is easy to implement and can be used to track users across multiple devices.

FingerprintJS: FingerprintJS is a source-available, client-side, browser fingerprinting library that queries browser attributes and computes a hashed visitor identifier from them. Unlike cookies and local storage, a fingerprint stays the same in incognito/private mode and even when browser data is purged. Since FingerprintJS processes and generates the fingerprints from within the browser itself, the accuracy is limited (40% - 60%). For example, when 2 different users send requests using identical (i.e. same version, same vendor, same platform), browsers, FingerprintJS will not be able to tell these two browsers apart, primarily because the attribitutes from these browsers will be identical. Fingerprint Identification is a closed-source, commercial device identification product designed for fraud detection, device identification, marketing attribution, and analytics.
