iOS 14 adds actually random MAC addresses: https://support.apple.com/en-us/HT211227

Thank you (and the other responder for the Android information too).

I stand corrected.

The observed behavior on my Pixel is that it generates a new, random MAC whenever you connect to a new network. It reuses that MAC for that network going forward. It does not ever use the "real" MAC unless you specifically select that in the settings.

> In Android 10, MAC randomization is enabled by default for client mode, SoftAp, and Wi-Fi Direct.

It randomizes per-SSID, so you get a random MAC per SSID you remember on your phone, this ensures privacy while not breaking DHCP / static IP etc.

What happens if you hit forget network? Does it also forget the MAC address for that network so you use a new MAC if you join the network again?

Just tested on my home network and it picked a new random MAC.
