Hello guys,
I would like to know how private can the use of different users is.
for example, I use facebook on the main user account on my Pixel phone, and I create a new user that I will name Tom, I install facebook and create a new account on the Tom User.
Does facebook know that the two accounts (mine and the freshly created Tom's account) are using a similar phone? if yes how? is it because of IMEI, MAC adress...?
Assuming that I use a VPN for Tom's account
Many thanks
