Need an unique id

Unity Engine
1

I know that deviceUniqueIdentifier is not supported for webGL. So I used Guid.NewGuid() and I save it to PlayerPrefs. My question tho, is there a way to have the same “id” for the device? Now I have a different key for Chrome and Firefox. Is it also possible to not save it to PlayerPrefs, so something like deviceUniqueIdentifier?

Unfortunately there is no way to identify a machine on the web using any kind of JavaScript/Web API. The feature does not exist by design - it is called “fingerprinting”, and is generally considered a violation of web privacy.

Though big companies do that all the time via different methods, e.g.:

So if you do want to identify a device, you’ll need to do that by some clever means like illustrated above.
