A browser fingerprint is a set of browser and device details websites can read, like your browser version, operating system, screen size, fonts, timezone, language, and graphics data.

In Multilogin, fingerprints are used in browser profiles. Each browser profile keeps its own fingerprint, cookies, proxy settings, and saved session data, which helps keep website accounts separated.

➡️ To check one, start a Multilogin browser profile → open Whoer IP or another fingerprint checker → look for signals that don’t match, like IP location, timezone, browser version, or operating system.

Why browser fingerprints matter

Websites don’t only look at cookies. They can also read browser and device details like screen size, timezone, language, fonts, graphics data, and operating system.

One matching detail is normal. But if many accounts share the same setup, they may start looking connected.

That’s where Multilogin browser profiles help. Each profile has its own setup, so your web accounts aren’t all walking in with the same “hi, it’s me again” signals.

The goal isn’t to make every profile look wildly different. The goal is to keep each one consistent, believable, and matched to how you actually use it.

How to check your browser fingerprint

Want to see what your browser profile is showing? Use these tools to spot mismatched signals before they become a problem:

• Whoer IP: check your IP address, location, timezone, and basic browser signals (default Multilogin checker)
• Pixelscan: check browser fingerprint consistency and possible mismatches
• BrowserLeaks: review detailed browser, device, WebRTC, canvas, font, and system signals

Here’s the process:

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

Good to know:

Don’t change fingerprint settings randomly just to “look different”. A browser profile should look consistent, not chaotic.

If you change proxy location, timezone, language, or operating system signals, make sure they still make sense together. Weird mismatches can look more suspicious than a simple setup.
