Are there any lawyers here that can speak about the legal side of this? I could imagine a wifi provider that offers 30 minutes free wifi e.g. airports, has this covered in their terms and conditions or a country that could consider this as fraudulent?
iPhones and Android phones do this for awhile already. If you read the article you'll notice that the MAC stays the same for a SSID for a working day. This makes sure it doesn't break networking and as a side effect captcha portal limits still work.
In OpenBSD, it's just: # ifconfig iwn0 lladdr random Of course, iwn0 is your interface.
NetworkManager also includes more advanced modes which make the MAC address stable for a given hotspot, but random between them.

MAC address randomization is in fact built in to NetworkManager (edit: 1.4), so none of this work is really necessary (edit: if you are on 1.4 or later).

From the post: "I learned that NetworkManager 1.4.1+ can do MAC address randomization right out the box. If you’re using Ubuntu 17.04 upwards, you can get most of the way with this config file."
Here https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoof... is how you can do it with newer NetworkManager.
Earlier quoted context omitted.
I am pretty sure that when iPhone connects to an access point it uses the real mac, I don't know about android but it is probably the same. Some access points need your real mac to connect because they use that to authorize you, I think schools/universities use this method a lot.
I do not understand though. Whitelisting MAC addresses is something you can do, but 99.99% of the wifi spots out there don't have it enabled. Why should my phone leak my MAC address needlessly instead of just generating a new one every 5 minutes or so?
Here is the code I use for my mac to randomize my mac address: interface="en0" new_mac=$(openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/:$//; s/./0/2') # from stackoverflow sudo ifconfig $interface ether $new_mac Edit: What's the advantage of the solution in the post? If I just change my mac address every time I join a network (even the same one), they can't track me with my randomized mac addresses. So why would I pre…
For example, calling the hotel desk to get your device to work.
