July 10th 2020 Apple announced that WiFi MAC Address randomization will be on by default in iOS 14:
https://support.apple.com/en-us/HT211227
I have tested the current iOS 14 beta and confirmed that it is on by default for all networks Open, WPA2 and WPA2-EAP:
- MAC Addresses are different per SSID
- Address changes are scheduled every 12 hours
- Address changes happen the next time a device reconnects to the network
- "Forgetting" and rejoining changes the MAC address each time
It also means that each random MAC consumes a DHCP lease.
For Hotspots which rely on MAC it means that trial/free periods are reset easily or automatically and paid vouchers are either lost, marked for overuse or require the user to login again.
How is Mikrotik Hotspot affected by this change? Are there mitigations/configurations to ease network management and user headbashing?
