Yes – the same browser profile can show different fingerprint results on another computer. The saved profile stays the same, but signals that depend on the computer’s screen, graphics, audio, or media devices can change.

➡️ For the most consistent results: use one main computer when you can. If you switch, keep the same operating system, use a resolution that fits both screens, and avoid very different devices.

Why can the result change?

Say you normally run a profile on a Windows laptop. Then you open it on another Windows computer with a different screen, graphics card, camera, and microphone.

Some fingerprint signals depend partly on that real device underneath the browser. So even though the profile itself is the same, the final read-outs can look different.

What can change?

Screen resolution

The profile resolution needs to fit the screen where you run it.

For example:

Profile: 1920 × 1080
Screen: 3840 × 2160
✅ No problem – the screen has enough room

But:

Profile: 1920 × 1080
Screen: 1366 × 768
⚠️ The profile is larger than the available display

Browsers can read the screen size and available display area, so it’s better when those values make sense together.

Media devices

Media devices are set to “Real” by default.

That means the browser sees the cameras, microphones, and audio outputs available on the computer you’re using.

Your laptop might have a built-in webcam and microphone. Your desktop might have a USB camera, external mic, and headset.

Switch devices – and those results can naturally change.

WebGL

WebGL has two different parts:

• “WebGL + WebGPU metadata” – masked
• “WebGL graphics” – uses persistent noise

The metadata covers details such as the graphics vendor and renderer.

The graphics result is different because the computer still has to do the actual rendering. If you move the profile to another GPU or graphics environment, the result underneath the noise can change.

Think of noise like an Instagram filter. Put the same filter on two different photos and you’ll still get two different final images.

So “Noise” doesn’t mean “show exactly the same result on every computer.”

Canvas and AudioContext

Canvas and AudioContext are “Real” by default.

Their results can depend partly on the computer and software environment, so switching devices can affect them too.

They also don’t need to be unique. Plenty of real users naturally share the same or similar results.

Why doesn’t Multilogin just mask everything?

Because more masking isn’t automatically better.

A fingerprint is made from lots of signals that need to tell one believable story. Changing one value is easy. Making every browser, hardware, and device signal agree with that change is much harder.

For example, forcing one graphics value while other signals point to a completely different setup can create an odd combination.

How can I switch computers with fewer changes?

You don’t need matching laptops. Just keep the setup reasonably consistent:

• Keep the OS the same – run a Windows profile on Windows, a macOS profile on macOS, and so on
• Avoid huge hardware differences when possible – graphics, audio, cameras, and displays can affect more signals
• Use a resolution that fits every screen – your smallest display is the safest limit
• Stick to one main computer when you can – fewer device changes mean fewer unexpected checker results

What if a checker shows a different result after I switch?

First, check which signal changed.

If it’s screen resolution, media devices, WebGL, Canvas, or AudioContext, the new computer may explain the difference.

A changed read-out doesn’t automatically mean the profile is broken or that its fingerprint was replaced.

If the checker reports a real mismatch, see How to fix browser fingerprint inconsistencies.

Can I run the same profile on two computers at once?

No. If the profile is already running on another device, you’ll see a lock icon instead of the start button.

Stop the profile on the first computer before starting it somewhere else.

Can switching computers get my account restricted?

Switching devices can change some fingerprint signals, but that alone doesn’t tell us how a specific website will react.

For a more predictable setup, avoid moving the same profile between very different computers more often than you need to.
