Easiest way to change your MAC address (unrooted)

[Paul B. Andersen]

What is the easiest way to temporarily change your MAC address
(for privacy reasons) on an unrooted iOS or Android device?

As you all know, the hardwired MAC address of your WiFi NIC is
(essentially) unique, and therefore, can be used to "tag" all
your communications when you are away from home.

That means that anyone at a Starbucks, McDonalds, public library,
etc., or even someone driving next to you on the freeway, can
uniquely identify that device as being a device they've seen
before (or not) if they simply bother to record the MAC address.

Therefore, it would be nice to change the MAC address daily,
as I already automatically do on my laptops.

But I don't know *how* to change the MAC address on my smaller
unrooted mobile devices, such as my iPads and my Android phones.

Googling, I easily find MAC address spoofing freeware which
requires a rooted device, such as:
Wireless Mac Address Changerm Osama Abukmail
https://play.google.com/store/apps/details?id=com.wireless.macchanger&hl=en

It's harder to find iOS MAC address changer software, but it
must exist.

Don’t change it daily, set it to 00:50:43:00:45:3e. Safety in numbers,
and all that.

"In iOS 8, Wi-Fi scanning behavior has changed to use random, locally
administrated MAC addresses," reads the slide, which can be
downloaded from Apple's servers as part of the presentation. "The MAC
address used for Wi-Fi scans may not always be the device零 real
(universal) address."

If you turn off the WiFi on your smartphone no-one will be able to
detect the MAC number or anything else. Only enable it when you want to
use it. There's at least one Android app that can turn your WiFi on and
off according to your location - "Wi-Fi Matic" by GZ Systems Ltd.

I know that doesn't change your MAC. But if you don't trust a router
with your MAC, don't connect to it.

You're on to something there, with the "safety in numbers",
If we all use the same MAC address, we can better hide.
Yes, I know we can't be on the same network, but, there's not much chance
of that since there aren't that many of us.

I like DE:AD:BE:EF:CA:FE myself.
It's the "foo" of MAC addresses.

It's not only the router you connect to, it's every single person in the
public library also.

It's probably easier to change the MAC address than to kick everyone else
out of the public library whenever you use their wifi. :)

I found this article which says "Android Terminal Emulator" freeware
will do the trick on half my systems:
http://www.techpluto.com/how-to-temporarily-change-android-mac-address-without-rooting/

They suggest Terminal Emulator for Android by Jack Palevich
https://play.google.com/store/apps/details?id=jackpal.androidterm

0. Find your MAC address in the settings about menu
1. Start the "Terminal Emulator for Android"
2. Get out your reading glasses because the text output is tiny!
3. Find the name of your WiFi card
4. Change the MAC address

Example on my system:
0. My WiFi MAC was 5c:0a:5b:a1:ff:00
1. I started the terminal emulator (& put on my reading glasses)
2. I typed "ip link show" (or "ip link show | grep -i 5c:")
3. That MAC address showed up as "wlan0"
4. I typed "ip link set wlan0 address de:ad:be:ef:cafe"
and "ip link set broadcast de:ad:be:ef:ca:fe"

The only catch was that I got an error "Operating not permitted",
so, it didn't work (yet).

If so, what's the "bar"? or the "Kung" :-) ? Cheers, -- tlvp

Personally, I think the web page was a scam.
You'll notice the guy who wrote it was:
a) Indian
b) Marketing major
c) Copied the information from a 2008 Android discussion
d) Selling advertisements

Given that, I am almost positive the web page (there is a duplicate
on another site by the same Indian author) is simply a dumb site
merely to generate user views, so as to sell advertising space.

I don't think, after researching this, that you *can* change the
MAC address without first rooting the phone.

Then, any of a number of methods work (e.g., ifconfig or set ip).

Here is the 2008 discussion the Indian marketing scammer probably
stole the information from in 2015 to generate page hits:
https://superuser.com/questions/91699/spoof-mac-address-from-ip-command

Notice the Indian marketing scammer didn't even correct the
erroneous command to set the "broadcast" address to
ff:ff:ff:ff:ff:ff (which isn't even needed because that's the default).

Anyway, I have concluded two things:
a) The Indian marketing scam web page is a lie,
b) You can't change the MAC address without booting to a rooted OS

If I'm wrong, I will be perfectly happy for someone to prove me
wrong, as I'd *love* to be able to change my MAC address without
having to root the thing.

BTW, what does "buck up" mean?

Anyway, here's another idiotic reference to the exact same
text, in this case, from 2014 (which again, probably just
copied the erroneous 2008 information):

http://androidforums.com/threads/how-to-spoof-mac-address.78668/

At least since that was on a forum, people refuted it in
the subsequent posts.

It's only on the Indian Marketing Scammer's blog that you can't
refute what the guy says. It has a comment section, but, I'll
bet the guy deletes all the comments because there are none, and,
you'd have expected at least one person to refute the information.

It's a NE Americanese phrase of encouragement, replacing "chin up", "cheer
up", "be of good cheer", "don't be disheartened", &c. HTH. Cheers, -- tlvp

Which sounds reasonable doesn't it? If a malicious app on your phone
randomly changed the MAC address (which it could do if there was no
requirement to be root), couldn't it play havoc with your
communications, giving you a denial of service problem?

Unfortunately, this kind of scam is run by people in the U.S. and
elsewhere in addition to people in India. I don't think it's India
specific.

To make the scam work, people use Google's adsense system. If you
complain to Google and provide the evidence that the website is just a
plagiarization of other sites, Google may cut them off from the adsense
program, but they might very well come back under a different name.

One of the funny things about this kind of scam is that the people who
do it typically aren't stupid and could probably make more money with an
honest job. Maybe it's the thrill of scamming people that attracts
them. Maybe dishonest work attracts them more than honest work, even if
it pays less.

Turning Wi‑Fi off only shut down internet connectivity on android. It will still connect to the first available open Wi‑Fi point, even if the whole phone is off.
