@n_dimension Apple does one unique MAC address per SSID unless it's an insecure/open network, and then it rotates your MAC address once every 14 days. It doesn't constantly change like people assume because that would be a great way to kill a poorly configured DHCP server with too small of a pool and too long lease expiration.
Android requires developer mode setting to make it always change, otherwise it only changes once per 24 hours or when the lease expires on an open network with no captive portal. Even deleting the SSID and re-adding it doesn't roll you a new MAC; it keeps the MAC address you used for that SSID forever unless you factory reset your phone
There probably are some slight variations on this behavior depending on vendor, but you wouldn't want to constantly have your MAC change.
and neither of these features even existed in 2013 --
For Android it was 2017, for Apple it was 2014
