What’s a browser fingerprint?

Think of your browser fingerprint like your device’s digital ID card. It’s a mix of info your browser shares with websites, like your IP address, browser version, screen size, operating system, fonts, and more. All these little details combine to make a 
unique fingerprint that websites use to recognize you – even if you clear your cookies or switch accounts.

Why should you care about browser fingerprints?

Because websites are basically digital detectives. They use fingerprints to:

• Spot and block sketchy or fake activity
• Stop fraud and fake accounts
• Track what you do across different visits

So if you want to stay under the radar and dodge bans – especially when juggling multiple accounts – keeping your fingerprint 
clean and consistent is a must.

How to check your browser fingerprint

Want to see what your browser is showing off? Use these tools to check your fingerprint and catch any weird stuff:

• Whoer IP: check your IP address and make sure it matches your intended location (default Multilogin checker)
• Pixelscan: get a detailed view of your browser fingerprint
• BrowserLeaks: spot any fingerprint inconsistencies that might expose your real identity

Here’s the process:

1. Start your Multilogin profile
2. Use one of the tools above to test your fingerprint
3. Look for inconsistencies in IP address, browser version, or OS
4. Adjust your settings in Multilogin to fix any mismatches

Will websites know I’m checking my fingerprint?

Nope! Websites can only peek at cookies that belong to their own domain. So:

• Multilogin cookies? Only Multilogin can see those
• Facebook cookies? Only Facebook’s business

This is called the Same-origin policy (SOP) – the browser’s way of keeping your info locked down.
