How can I check my fingerprint?

There are multiple publicly available resources that you can choose from. Among them are whoer.net, browserleaks.com, our own in-built checker app.multiloginapp.com/WhatIsMyIP and many more.

Why should I update the browser core?

A browser core update in Multilogin looks the same to websites as a regular user updating their Chrome or Firefox. This action doesn't cause any restrictions or logouts.

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 access cookies associated with their own domain. In other words, Multilogin cookies are visible only to Multilogin, while Facebook recognizes solely its own cookies. This principle is known as the "Same-origin policy" (SOP), a foundational concept dating back to the creation of first browsers.

Why is the real WebGL and canvas fingerprint better than the masked one?

By default, noise is disabled in Multilogin profiles, which allows websites to read the real WebGL and canvas hashes of your device. This approach is advantageous for the majority of popular websites that react badly to 100% unique readouts.

WebGL and canvas fingerprint hashes are not unique: multiple copies of your device setup exist elsewhere in the world. So by revealing your real hash, you only fall within the segment of users with the same hardware setup. 

If I open one profile on different computers, will its fingerprint stay the same?

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 "Masked" and "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 a hardware fingerprint mismatch. To avoid simultaneous launches, you can use groups for your browser profiles distribution.

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.

Why does my font hash remain the same?

Curious why the font hash remains constant in both regular and Multilogin browsers? Don't worry, it's perfectly normal!

Picture this: your computer has standard fonts A, B, C, D, and E. A website, however, checks for specific fonts A, C, and E. If they're present, they get hashed; otherwise, the remaining fonts are hashed.

Now, let's say you've expanded your font collection with new additions like X and Y. Despite the larger font set, the website still checks only for fonts A, C, and E. Consequently, the hash remains untouched. This principle holds true for Multilogin as well; even if you add extra fonts to emulate typical user behavior, the hash might stay unaltered.

The only way to alter the hash in this scenario would be removing one of the standard fonts. However, doing so might compromise your antidetect strategy. Therefore, having an identical font hash in both regular and Multilogin browsers should not be a cause for concern.
