Connection sharing, which device is identified?

Hello,

We can always "ping" your IP address, or trace the route... but I don't think we can get the MAC address..??

However, wifi analyzers installed on an Android are capable of seeing all the IPs and MAC addresses and SSIDs of your network...

If you want to avoid these risks, install a 4G router with Ethernet ports... and connect your devices via Ethernet.

The SIM card from your iPhone being in this router...

Good evening @jeannets StatutContributeur and thank you for your response.

I think I understand what you mean, and what I would like in this specific example is to prevent the MAC address of the iPhone (yes, I only have 2 iPhones ^^') that shares the connection from being detected by the website in question, and that only the iPhone receiving the share is detected as such. I think that since the "transmitting" iPhone only shares its network, technically we shouldn't see anything about it, other than the network it shares, but I just want to be sure. I want to ensure that the site in question does not identify the device that is sharing the connection, but only the one that receives it.

Beyond that, I don't know how websites are made, regardless of whether they are sales sites or anything else; it's just the question I'm asking and what I want to make sure of.

Hello,

I'm wondering why you're worried, everything you're saying is impossible without adding spyware to the phone:

there's no MAC address on the mobile network side and behind a router (with the mobile in tethering) you can't see the MAC addresses on the other side of the router.

However, a website, through cookies and other means, can install something to recognize you when you visit it.

So there it is ....

But goodness, those line breaks are so annoying!!

Hello to you @brupala StatutMembre and thank you for taking the time to respond

The reason I'm asking all this is simply because there are a few people in my circle who have been on all kinds of websites and are no longer allowed to access them for reasons I don't know, but they've told me that their devices have been blacklisted, so I'm not really sure what that means and I've tried to find out a bit about it, and it seems to mean that it's their devices whose MAC address has been banned. I think we can all agree that every device has an email address on its network card, whether it's a PC or even a mobile

So I think that any website, no matter which one, can identify a mobile with the MAC address as long as it's connected to a modem via Wi-Fi, for example!

But I simply didn't know if a mobile, an iPhone more specifically, that shares its own connection can be identified on the site, even if it's not the one visiting the site in question. I know it's a bit complex as a request, but let's say I'm trying to formulate my question as clearly as possible

@brupala StatutMembre Let's take a more concrete example so you can explain your solution or your explanation a bit. Suppose I create an account on a selling site, you know, eBay! Etsy, whatever, I make my account, I create my listings, and suddenly my account is suspended, like, permanently. You see, even though I haven't done anything illegal or wrong, by the way.

Knowing that I imagine they have taken almost all my information and collected most of the data about me, I change:

– my IP address, dynamic IP

My phone number because I have two lines

Email address and that's it, and I create another account with all this changed information! And I get my account automatically suspended not even five minutes later… How can you explain that?

Because everything has been changed, except for the device which retains the same MAC address since it is a unique identity for each device.

I took the example on a selling site, but it could be on any website, so let's say it's not a blacklist of the device's MAC address in question, but what could it be because there aren't many things, especially if we change all the information… So could it be something related to cookies as you would say, and if so… What is the link to the device given that we've changed absolutely everything?

Hello

especially if we change all the information

And what about the cloud and device synchronization?

You shouldn't reload information that you've deleted, either.

@Tsuyoi StatutMembreUh, I'm suddenly lost!

Do I need to log out?

Well, if your boyfriend is in a situation where you are not, he must have made a mistake somewhere.

If you handle it well, that's fine.

Well, that's exactly the problem. The thing is, maybe he made a mistake somewhere, and I would really like to avoid that mistake, actually... So apparently, I'm being told that if I go to a website using a shared connection from another phone, only the phone that's accessing the site will be "identified" in terms of hardware or any level, and not the phone that's providing the connection... At least, that's what I understood. After that, I didn't really grasp what was said regarding cookies and all that, and I didn't quite understand the relation... So I'm waiting for a little clarification.

Cookies are placed on your computer by websites.

If there are none, two computers cannot connect on the internet.

You request a page from a site; without the cookie, the server doesn't know which computer to send it back to.

And there are others that allow you to store more information either on your computer or on the site.

There are settings in your browser, for example, that allow you to delete all cookies when closing the browser or by clicking a button in the settings.

If you synchronize your devices, you can re-download information from another device, like the computer, regarding your browser to your phone, including the bookmarks you saved on the computer that weren't yet on the phone.

Well, you say you don't have a computer, which isn't possible if you are coming from a computer, but your friend might have one.

@tsuyo StatutMembre So, I know that he was doing it directly with the mobile app, yeah because he was on the sales sites or whatever, but with an app, so let's forget the app, since it's the kind of thing that gets stuffed with cookies and various info about us so..

As for me, if I go on sales sites like that, to be protected and not to "jump," I think it will be in private browsing, without accepting cookies, with a VPN or sharing a connection since the phone that will do the sharing won't be compromised, so I think if I do that, in my opinion, it should be good?

For my colleague, he didn't do anything special, normal browsing, accepting all the cookies, downloading the app & others, me, let's say I'll take a little more precautions.

So, if I refuse all cookies, the server in question won't know where I'm coming from, or where the device in question is coming from, whether it's on Wi-Fi or through sharing a connection, well, if I summarized the whole thing correctly? (refusal of cookies + private browsing)

@tsuyo StatutMembre @brupala StatutMembre do you think that sales websites check the banks to which the bank accounts are linked? Because in the case where a profile is in one name but the bank account in another for X reasons, I don't think that could be a problem?
