When it comes to online privacy and avoiding detection, there’s a common myth that every single browser fingerprint needs to be masked. But that’s not the case. Multilogin takes a research-backed approach to fingerprint masking, ensuring that only relevant parameters – the ones websites actually track – are customized.

The myth of total anonymity

Some users run advanced fingerprinting tests and notice similarities between Multilogin browsers and regular browsers in certain parameters. This leads them to ask: 

Why doesn’t Multilogin mask this specific value?

The reason is simple: not every fingerprint parameter matters. Some values are either invisible to websites or not checked at all. Trying to disguise every detail can actually make your fingerprint more suspicious rather than blending in.

Multilogin is the only company in this space that invests heavily in research and development to truly understand how antibot and antifraud systems operate. Instead of blindly masking everything, we focus on what websites actually track.

Non-essential fingerprint parameters

MAC address

Your MAC address is not visible to websites through a browser. It’s part of your local network and doesn’t get passed along when browsing. There’s speculation that Google could theoretically extract it through Chrome, but there’s no real evidence of this happening. If you have concrete proof, we’d love to hear about it.

SIM card ID

Websites cannot extract your SIM card ID when using a 4G connection. This data is not accessible via browsers.

Glyph hash

Glyph fingerprinting depends on factors like browser version, window size, and OS. Many users end up with the same glyph fingerprint, making it useless for tracking. 

ClientRects

This parameter reflects how a browser renders HTML elements at the pixel level. While some fingerprinting tools display this value, there’s no real evidence that major tracking systems (like Cloudflare or FingerprintJS) rely on it. 

JA3 hash / TLS/SSL fingerprint

Masking this would give you a unique fingerprint, making you stand out. Multilogin ensures your TLS/SSL fingerprint matches your browser profile’s User-Agent, helping you blend in naturally.

The bottom line

Multilogin only includes fingerprint masking features that actually matter. If a parameter isn’t being disguised, it’s because: 

• Websites can’t see it 
• It’s not checked 
• Masking it would make you stand out more

Instead of obsessing over every tiny fingerprint value, focus on what truly impacts detection. That’s the smarter, safer approach.
