        Maybe because they bought iPhones. ๐Ÿ˜‰ <ducking>

        With Android, it appears to generate a random MAC when first connected to an SSID and then use it for all future connections.

        I haven't lost my mind. It's around here...somewhere...

          LOL no ****, itโ€™s in the interest of Google to be able to track you by MAC address when ever you join a Wi-Fi network if the MAC stays consistent per SSID they are sorted.

            Both Android and iOS appear to do the same for new networks; use a random MAC but that keep using that for re-connections to that same network.
            The only thing that seems unclear is their behaviour when connecting to already known networks.
            It seems iOS is using a random MAC there too potentially breaking stuff.
            Android seems to retain the real MAC for existing networks as reported above.

              Yes, when I got my Pixel 2 and synced it to my previous phone, it also received my WiFi connections. They use the hardware MAC. A connection I set up a couple of weeks ago uses the random number.

                It is so funny to see some Netgate forum members always bring up TIN FOIL HAT every time someone asks or says about privacy & security.

                @bcruze, Mac Private address is just a layer of security. The same as T2 chip and read-only system volume in Catalina. Apple is aware that their previous devices were easy target for hacking. Not to mention the leaking on intel chip issue.

                  Security and Privacy are not the same thing. Just saying...

                    Let me explain the differences between them;

                    Security = Protection of a person, building, organization, or country against threats such as crime or attacks.

                    Privacy = Someone's right to keep their personal matters and relationships secret.

                    Everyone has the right for security and privacy.

                      Interested in your thoughts about things like:

                      Random MAC addresses may prevent you being identified across public WIFI networks (at the mall or airport, in whole foods) but that is small comfort when your cell service provider is handing over location data in bulk, with little or no legal process, to any interested party.

                      Targeted exploits are rare. The bad actors don't care about you unless you are a celebrity or other notable individual. It's much more likely, however, that you will get caught up in an exploit of some widely used service or device. It's not personal ;)

                      Risk vs Benefit. It shouldn't be as hard as it is to work that analysis through. It's understandable that a lot of people spend at least some amount of time in tin foil hat territory.

                      I've been intentionally vague to facilitate conversation. Of course I would prefer to not have Amazon forcing preventing me from using my cell providers network while in Whole Foods AND my cell provider to not be coughing up my location data.

                      I'm certain that I do regularly suffer from cognitive distortions and well informed conversation is the best way to mitigate that.

                          Yup. They block cell signals. I've never been able to get a cell signal inside a Whole Foods. If you want to use your prime account you have no choice but to use their wifi network. So, point taken, I could just pay full price and not access their network.

                          I'm not a RF engineer but it appears to be passive blocking (faraday cage). Step outside the building and I get a full strength signal.

                            I don't really recall noticing this last time I was in a whole foods.. Last time was before covid.. Quite often stop at their in store taverns.. Tuesday's is 2$ bottle and can day at their instore bars.. And they normally have a decent selection..

                            So stop there after work many a tuesday for couple of cold ones ;)

                            But sure it behooves stores like this to control your internet access while your in the store, can prevent you from doing price compares, etc. Or atleast make it way more difficult - since hey odd how you can't get to store xyz site while on the whole foods wifi ;)

                            Problem could also be cell coverage in the middle of a HUGE store might just be spotty? But do believe amazon a few years back had a patent on such thing as controlling people in their stores internet access..

                            But force prob not the right word, more like direct you to their connection ;) Nothing saying you can't just leave your phone at home or in the car, or just turn it off, or put in airplane mode, etc.

                              As I remember Best Buy was doing that at some point in time. Blocking access to mitigate using Best Buy stores as an Amazon showroom. Haven't been in a Best Buy in a dogs age so I can't comment on the current situation.

                                    Maybe you missed the part where I said I got your point. I'll repeat it here: "So, point taken, I could just pay full price and not access their network."

                                      Yeah persuade or direct, nudge might be better terms vs force ;)

                                      I can still just use them as amazon showroom... Without any internet access there, just know before hand what I want to look at.. Go look at them, and then order or not when get home.

                                      Saving a nickel on the all natural peanut butter though - this really is heavy handed forcing if you ask me ;) hehehe

                                            So true, so true.. But not only "security" privacy as well.. Do I really want to make it easy for store xyz to know my purchasing habits, for the X% discount they give me if I use their rewards card, etc.

                                            People screaming about privacy, yet give their info away freely if there is anything in it for them that they value more... Like 0.05% discount on purchases, or get 1 free after I buy 5.. etc..

                                            And then scream about getting ads for XYZ in the store app on their phone - how did they know I like that?

                                            You can not have your cake and eat it too.. The whole reason company gives you discount X, is they know they will pull you back more often, or can use that info to get you to buy more, or sell that info to someone else - So they end up making way more than the tiny discount/reward they give you..
