How to Check Configuration File Fingerprint

Check fingerprint CN

Ready to check if your profile fingerprint is secure? Checking your fingerprint is very simple, so let's get started right away!

Use these tools to check your browser fingerprint:

Whoer IP: Check your IP address and make sure it matches your expected location (default Multilogin checker)
MaxMind: Used to get the most accurate IP geolocation details
Pixelscan: Get detailed information about your browser fingerprint
BrowserLeaks: Detect any fingerprint inconsistencies that might expose your real identity

Can websites see that I visited the 'Whoer IP' page or other checkers?

No. If you’re concerned that a website could read its cookies and detect that you are a Multilogin user, we have good news for you!

Websites can only access cookies associated with their own domain. In other words, Multilogin cookies are only visible to Multilogin, while Facebook only recognizes its own cookies. This principle is called the "Same-Origin Policy" (SOP), a foundational concept dating back to the earliest web browsers.

Here’s how to check your fingerprint:

Open your Multilogin profile
Test your fingerprint using any of the tools mentioned above
Look for inconsistencies in your IP address, browser version, or operating system
Adjust settings in Multilogin to fix any mismatches

How to Handle Fingerprint Warnings

Fingerprint warning? Don't worry—it just indicates that there might be an issue with your settings. Investigating and fixing them is easier than you think.

Hardware Warning

This occurs when your actual operating system (OS) does not match your profile settings.

For optimal stealth: Use your native operating system in the fingerprint settings (for example, if your native operating system is Windows, select Windows as your profile OS)
Optional mix: If your fingerprint OS does not match your real OS, the reliability of the fingerprint will be reduced

Location and IP Warning

These are usually caused by global IP issues.

Quick fix: Use a top-tier residential or mobile global IP to completely mask your location (we recommend using our built-in solution – Multilogin Global IP)
Pro tip: Avoid using free or low-quality global IPs—they will only cause more problems

Browser Version Warning

Using outdated browser versions may make you look out of place (not a good thing), and it can even lead to certain website accounts being suspended.

Keep it updated: Always use the latest browser core version
Check your User-Agent: Ensure it matches the latest browser version and your emulated operating system

Customizing your User-Agent in the “Navigator” section? Cool, but be careful. Mismatches between the browser version and the emulated operating system may trigger warnings. Only adjust these settings if you know how to use fingerprinting.

Following these steps can improve your security and help you avoid unnecessary warnings.
