How to remove browser version in order to get the same visitorId even if the version changes?

[bergmp]

I am trying to identify users with fingerprintjs. However, when browser version changes visitorId changes but the user is the same.
How to solve that?

Hi @bergmp!
The specific browser version is not an entropy component (or signal) for the visitorId. However, it's plausible, an update of the browser can change some entropy sources. To identify which entropy component affects the final visitorId I'd recommend comparing the result object. Then you can easily exclude the specific entropy source.

// ...

const result = await fp.get()

// The `languages` and `audio` components will be excluded
const { languages, audio, ...components } = result.components

// Optionally, you can make a visitor identifier from your custom list of components
const visitorId = FingerprintJS.hashComponents(components)

Nevertheless, please note, by excluding some entropy sources you might affect sensitivity (the number of unique fingerprints).

Thanks for your support.
