Glad this feature is built into most modern operating systems these days.

For MacOS (Sequoia+) you can just forget the network and reconnect to get a new MAC address [1].

Android's documentation for if it decides to generate a new address per connection is a little vague [2], but I'm guessing forgetting and reconnecting works as well, you may also need to flip the "Wi-Fi non-persistent MAC randomization" bit in developer settings.

On Windows, flipping the "Random hardware address" switch seems to cause it to generate a new seed/address for me.

Per [1], this only works once per 24 hours on new iOS/macOS versions, and only once per two weeks on older ones though.

Yeah I had to flip the developer setting toggle, but worked flawlessly for my flight (American Airlines has a watch an ad for 20 minutes of free internet that only works once per MAC)

		Are you saying that on IOS 18 if you enable developer mode then each time you forgot the network it gets a new Mac? But without developer mode it does not get a new Mac each time you forget it? The Apple docs linked elsewhere in this thread suggest it only gets a new Mac once per 24 hours when you forget the network normally. I’m going on a long boat trip in the next week where this trick might work for me if so!

I have a generic Android phone from many years ago where the manufacturer didn't even bother to program the WiFi NVRAM, so every time you load and unload the driver, you get a new randomly generated MAC address. Interesting that that has become a feature these days.

I think the rotating address is limited to 3, right? The script here generates one at random.
