How can I check my fingerprint?
There are several resources that you can use.
- Our own in-built checker: https://app.multiloginapp.com/WhatIsMyIP
- Such websites as www.whoer.net, www.browserleaks.com, www.pixelscan.net, and others
Why should I update the browser core?
For websites, a browser core update in Multilogin looks like typical behavior of a regular user who updates their Chrome or Firefox browser to the latest version. This action doesn't cause any restrictions or logouts.
Remember: browser updates affect more than 80% of all trackable users. Since browser versions are not unique, by using the latest available core, you fall into a large segment of regular users who do the same.
Can websites see the WhatIsMyIP page?
No. If you are worried that websites will read its cookies and find out that you are a Multilogin user, we've got good news for you :)
Websites can only see those cookies that belong to the domain that requests them. This means that Multilogin cookies can be seen by Multilogin, Facebook will see cookies from Facebook, etc. This is called the same-origin policy (SOP), which exists since the creation of browsers.
Therefore, there is no need to worry that other websites will see that you’ve visited this page: https://app.multiloginapp.com/WhatIsMyIP.
Why is the real canvas fingerprint better than the masked one?
By default, canvas noise is disabled in Multilogin browsers, which allows websites to read the real canvas hash of your device. This approach is advantageous for the majority of popular websites that react badly to 100% unique or blocked canvas readouts.
Canvas fingerprint hashes are not unique, since multiple copies of your device setup exist elsewhere in the world. So by revealing your real canvas, you only fall within the same segment of users who have the same hardware setup. Furthermore, by altering other fingerprints, you can increase the entropy so that websites see your browser profiles as separate identities.

If I open a profile on different computers, will it have the same fingerprints?
If those computers have different hardware, there can be a hardware fingerprint mismatch. You can get non-changing read-outs on multiple devices using one of the solutions below.
- Run Multilogin on identically configured Virtual Machines (VM) or Virtual Private Servers (VPS) with Hardware fingerprints set to Noise
- Run Multilogin on identical PC models with the same hardware, driver, and OS setup
- Run Multilogin on the same Mac computers

Can I use the same profile on different computers at the same time?
We don't recommend it, as this may corrupt your session data and result in the hardware fingerprint mismatch. In order to avoid simultaneous launches, you can use groups for your browser profiles distribution.
Additionally, Team and Scale plans have the active session lock feature, which prevents users from accessing the same profiles if they are already running.
Can websites see my MAC address?
According to our research, websites cannot detect your MAC address through a browser. It is a part of the low-level network stack and is not propagated from one subnet to another. We also have a blog post on this topic here.
