The identifier's limits: Apple's support page explains that a device identifies itself to a Wi-Fi network by a unique network address called a Media Access Control (MAC) address and that its Private Wi-Fi Address feature exists so that one address is not used across all networks; Android's documentation describes persistent and non-persistent MAC randomisation and states that if the user disables it, the factory MAC address is used.
