GitHub - fingerprintjs/fingerprintjs: The most advanced browser fingerprinting library.

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.

FingerprintJS 是一款源码可用的客户端浏览器指纹库，它通过查询浏览器属性并计算生成哈希化的访客标识符。与 Cookie 和本地存储不同，该指纹在隐身/隐私模式下依然保持不变，即使清除浏览器数据后仍会保持相同。

<script>
  // Initialize the agent at application startup.
  // If you're using an ad blocker or Brave/Firefox, this import will not work.
  // Please use the NPM package instead: https://t.ly/ORyXk
  const fpPromise = import('https://openfpcdn.io/fingerprintjs/v4')
    .then(FingerprintJS => FingerprintJS.load())

  // Get the visitor identifier when you need it.
  fpPromise
    .then(fp => fp.get())
    .then(result => {
      // This is the visitor identifier:
      const visitorId = result.visitorId
      console.log(visitorId)
    })
</script>
