Is the browser window size a parameter for generating the fingerprint?

[Chevindu]

Hi,
I saw in one of the discussions that the user's screen resolution and browser's frame coordinates (positioning I assume) are considered as parameters for generating the fingerprint. I was wondering if the browser's window size is also a parameter for this. I hope it's not a foolish question, because I am not aware of the technology behind this.
Thank you.

HI @Chevindu! It's not a foolish question at all :)

Screen resolution is one of the signals used for fingerprinting, but window size and position are not. You can have a look at the FingerprintJS demo: https://fingerprintjs.github.io/fingerprintjs/
which shows a JSON of all the data that is hashed into a fingerprint.

You can try resizing your browser window and reloading the demo page, you will see that the fingerprint does not change. However, dragging the browser window to a second monitor with a different screen resolution than the first one will change the fingerprint.

The visitorId provided by Fingerprint Pro (as opposed to the open-source Fingerprint JS) is much more stable: https://fingerprint.com/demo/
