This question already has an answer here:. 2 answers I have searched other results and read many of them but I could not get an enough information. My question is that can a website see my MAC address or can they have an information about that I'm the same person under these conditions:.

I am using a VPN and I use two IPs: first one is normal one, the second one is the VPN's IP. I use two browsers to hide behind browser fingerprinting. I use both browsers with Incognito Mode. I always use one for normal IP, one for the VPN IP.

I do not know that if the website uses cookies or not. But can they collect an enough information to prove that these two identities belong to same person?

Is there any other way for them to see that I am the same person? I use different IPs, different browsers and I use both browsers in incognito mode. I even changed one of browsers language to only English.

So even if they collect my info from browser, they will see two browsers using different languages. (Addition after edit): So I have changed my IP and browser information and the website can not reach this information anymore to prove that I am the same person using two accounts. Then let's come to the title: Can they see my MAC address? Because I think that it is the last way that they can identify me and my main question is that. I wrote the information above to mention that I changed IPs and I have some precautions to avoid browser fingerprinting (btw my VPN provider already has a service about blocking it). I wrote them because I read similar advices in some related questions but my question is that can they see my MAC address (or anything else that can make me detected) despite all these precautions.

And lastly,. Is there an extra way to be anonymized that I can do? For example, can my system clock or anything else give an information?

Thanks in advance. No Daniel, my question is about MAC address actually. The things I mentioned in my question details are because of that I already changed the IP and then there will not be a problem about using same IP. This title is wrong now because my question is about MAC address. I already said that my IPs are different in two different browsers. The thing I wanna know is that if they can see my MAC address or not despite all these things I do.

So I will be glad if the title is changed back to MAC address because my main question is that. – Aug 24 '14 at 21:33. The only web sites that can access MAC addresses, are sites that have you download a software component to interface with them, which allow the site to circumvent the usual rules. So you technically have to give permission first by doing that. ActiveX & WMI (Windows Interface via Windows Management Instrumentation) for Internet Explorer and Java are methods used that could pass on a MAC address. ActiveX requires WMI is installed for this to work.

Here is a script using WMI that reads MAC addresses: NOTE: this link is now dead, but the script previously hosted at that location did the job for WMI enabled Windows-based computers so still needed as information for this question. Here is a question with code to do this in Java on StackOverflow: As mentioned in the comment below by Hennes, MAC addresses are internal only. Web servers do not generally pass on that information.

Just the IP addresses, and even then- users often only show the IP address of their location. If you are going to a web site for example, in a coffee shop, the IP shown is that of the coffee shop, not a user on the network. Regarding IP addresses- JavaScript can use WebRTC (these examples for newer versions of Chrome and Firefox) now to show internal IP addresses as explained in this article: See live working examples here: and one that attepts to detect all ip addresses in your local range here: This is not to be confused with MAC address data. If your JavaScript is turned off this will not work of course. Since it was mentioned in the question, JavaScript reads the time from the clock on your system.

When you post from one page to another in a form, it could post the time from javascript, giving away the time zone you are in. Applications that use real-time like online bid applications do that. If that is different than the time the server sees that would be a 'flag' so to speak. The solution is to kill JavaScript or change your clock time.

By itself it doesn't give much out though. Not everyone has their clock set properly but most have them auto-sync with real timeservers especially mobiles.

In the comments below, specializt mentioned that WMI can be disabled. So can ActiveX, JavaScript, and Java which can simply be uninstalled. The cookies by themselves get server time, not the time from the web browser. If you want client-side time, the JavaScript method I mentioned above is a way to do it. If you are looking at a site, and two web browsers come up from the same ip (which yours would if you did not use proxies)- it would not be necessary to check a cookie to know they came from the same location. The IP log tells them that. They cannot know it was from the same computer in the 'lab', but it may be guessed because they are in the same time slot in the web log.

That may not help - one person or a person with an accomplice. It could be seen in that light. Proxies would resolve the server log IP problem of course. Both browsers using a different proxy location like you mentioned is great. Firstly, thanks for your answers Jeff and Hennes. They are the bests I saw so far. @Hennes, I heard that the MAC of computer cant go out of router, but still the router's MAC address information is going to the ISP and then to the website etc.

I mean, they can not see my computer's MAC but still they can identify me by seeing the same MAC of the same router I think, am I wrong? In addition to all, what ways can a website reach to prove that two accounts belong to the same person else than IP, browser information (language, screen res etc.) and MAC? Am I anonymized and safe? – Aug 24 '14 at 21:57. The others have already answered you main technical questions and my comment to some of them answer your doubts about MAC address.

So I'll just concentrate on this: And lastly, Is there an extra way to be anonymized that I can do? For example, can my system clock or anything else give an information? Yes, there is one more thing that can trip you up: your personality. What you're trying to do is called sockpuppeting. You may have noticed that some sites like Stackoverflow and Reddit have moderators. They're the last-line defence against sock puppets.

And in my personal experience is that they base their detection primarily on 'hunch'. Once they have a hunch that something is fishy they'll usually dig your posting history and find phrases or political views or mispellings or any pattern that's consistent. That is how sock puppet detection is done once you get past auto-detectors like referrer detection or IP address detection or username similarity detection (it's amazing how some people insist on using discoverable patterns when choosing usernames) etc. Against another human it's quite hard to avoid detection unless your second account does not do anything at all that's related to your first account. Then again, that generally defeats the purpose of sock puppets.

A client's MAC address is used by the layer 2 protocol, eg ethernet, to uniquely identify each node on the local network. It is most likely that the web site that you are reaching is NOT on your local area network and hence will not see your MAC address. For sake of illustration lets say you have a PC on a LAN and you want to access a web site, eg google.com. First thing you need to do is find the best route to google.com. This will be via a router. Most likely some sort of broadband router. If you are on ethernet, your networking systems places an ethernet frame round chunks of data in your request.

In each frame there will be a to MAC address and a from MAC address. The to MAC address is the MAC address of your router and the from MAC address is your PC MAC. The router, when it receives the frame will strip off the frame and reframe it for the next leg of the journey. I don't know much about ADSL framing but there will still be a frame used - some sort of dsl type frame. This time the to MAC address will be the MAC of the next node on the route to google.com. The from MAC will be the MAC of the broadband side of your router. So you see, google.com will never see your PC's MAC address.

It sees your IP address, sure, but not your MAC. I think it's fairly obvious that software running within your computer can provide virtually any information needed to break your annonymity. So, it may be software accidentally installed. If it has access to the network later and the software layer, it can probably talk to itself to establish a connection through both networks and give your identity up. I believe that running two virtual machines is a slightly stronger method, although not perfect. There's very little chance of software within a virtual machine speaking to another virtual machine if you set it up right, however, of course software within the virtual machine may broadcast the MAC address to something that can be matched up. At the end of the day they may still match similar usernames, or other patterns, and there is little you can do about that.

It depends on the web site you are accessing and what special scripts run on their servers. For example: When you connect to a wifi hotspot, you will first be directed to a login web page where you have to enter your credentials to be given farther access to the Internet.

If you check the address bar of that login page, you will discover your MAC address in there and most likely the MAC address of the router you are connecting to. You don't need to have installed any special software on your computer. A script, which is downloaded by the browser from the server where the login web page is located, does that.

That is, the script reads the information about your network adapter and creates the complex string placed in the browser address bar. After you login, the information about your MAC address sent by your computer and your credentials (user id and password) are placed in a database by the wifi hotspot provider. From that moment, on every time you connect to that wifi network (regardless of the physical hotpsot), your MAC address will be checked against the database. If the credentials are still current and valid you will be given access to the Internet, without the need of another login. Your MAC address and/or your credentials can be farther used by the wifi hotspot provider to monitor and limit your access to the network based on length of access, time of access, amount of data transferred, type of data accessed, etc.

To answer the original question, a web site can read your MAC address, but they need to have special scripts on their servers and force your browser to download them.
