I couldn't test it on all platforms and all update types, but knowing the technical background it should be the same after system updates.

if user performs factory reset, then seems the UUID gets changed.

@youngmob but does the keychain get reset? I think its known that the UUID can change, but this plugin doesnt rely on Device UUID and instead generates an Id and stores it in the keychain.

So what some of us are really trying to understand is under which circumstances is the keychain reset or cleared?

It seems that for windows os the UUID gets changed.
