font-fingerprint v1.0.1

font-fingerprint

font-fingerprint is a library that generates a unique identifier for each visitor based on the installed fonts of the browser.

Almost fingerprint libraries are based on the various browser features. Even with the same device, different browser types can generate different identification values.

font-fingerprint is free from these constraints because it only considers the types of installed fonts.

This library is inspired by fingerprintjs.

Install

npm install font-fingerprint

or

<script src="https://cdn.jsdelivr.net/npm/font-fingerprint@1.0.0/dist/index.min.js"></script>

Usage

import getFingerprint from "font-fingerprint";
