A fingerprint warning means a checker found a browser, device, or network signal it considers unusual or mismatched. It doesn’t automatically mean your profile is broken.

➡️ Start with the exact signal that was flagged: right-click the profile → select “Edit” → check “Proxy” for network issues or “Fingerprint” for browser and device signals.

If you didn’t customize the flagged setting, don’t change it just to satisfy a checker.

Before you change anything

Use one simple rule:

• You customized the flagged value – check your changes first and make sure the value still makes sense with the rest of the profile
• You left it at the default – don’t change it just to make a checker happy

Then find the type of warning below.

Network and location warnings

Start here if something looks wrong with your IP, country, WebRTC, timezone, or geolocation.

Wrong IP or country

First, make sure the intended proxy is connected and working.

If the IP is correct but the country or location looks wrong, check the same IP with another lookup tool before changing your profile. IP location databases can sometimes disagree.

WebRTC, timezone, or geolocation

If you customized these values, make sure they still make sense with the proxy you’re using.

If you left them at their defaults, Multilogin handles them automatically based on the proxy setup. If the mismatch keeps showing, contact support rather than changing unrelated settings.

Browser and operating system warnings

Check this section if the checker flags your OS, browser version, User-Agent, platform, or Navigator.

Operating system

The profile OS should match the computer where you run it.

For example:

Windows profile + Windows computer ✅
Windows profile + macOS computer ⚠️

The operating system can’t be changed after the profile is created, so choose it carefully when setting up a new profile.

Browser version

Multilogin manages the browser core for you.

• Mimic: it may sometimes be slightly behind the latest Chrome release while the next tested core update is being prepared
• Stealthfox: it’s a legacy browser and no longer receives new browser cores – its final available core is version 146

You don’t need to manually pick a browser core.

User-Agent and Navigator

If you’ve customized these values, make sure they tell the same story.

For example, the browser, platform, operating system, and hardware information shouldn’t contradict each other.

Intel and Apple Silicon on Mac

Seeing Intel wording on an Apple Silicon Mac doesn’t automatically mean you’ve found a mismatch.

Chrome uses compatibility values for some macOS browser signals. You may see:

User-Agent: Macintosh; Intel Mac OS X 10_15_7
navigator.platform: MacIntel
WebGL: Apple M-series hardware

That combination can be normal.

Device setup warnings

Use this section if the checker flags screen resolution, fonts, or media devices.

Screen resolution

Make sure the profile resolution fits the computer you’re using.

A smaller profile resolution on a larger screen is fine. The problem is the other way around – for example, a 1920 × 1080 profile on a 1366 × 768 display.

If you use the same profile on several computers, choose a resolution that fits the smallest screen.

Fonts

A shared font hash doesn’t automatically mean two profiles are linked.

Don’t try to force a different result just because a checker shows the same hash in several profiles.

Media devices

Cameras, microphones, and audio outputs should make sense for the device setup.

If you’re using “Real”, switching computers can naturally change what the browser sees – your laptop and desktop probably don’t have exactly the same cameras, microphones, and speakers.

Canvas, WebGL, WebGPU, and AudioContext warnings

These signals can depend on the browser, operating system, graphics hardware, audio environment, and the way the profile is configured.

The most important thing to remember is:

Shared isn’t automatically bad, and unique isn’t automatically good.

Two real computers can share the same graphics hardware or produce similar results. At the same time, making every profile artificially different can create combinations that don’t look natural.

So don’t change Canvas, WebGL, WebGPU, or AudioContext just to get a different hash or a “100% unique” result.

If you’ve customized one of these settings, check whether it still fits the browser, OS, and hardware represented by the profile.

What if two checkers disagree?

That happens.

Fingerprint checkers use different tests and scoring methods, so Whoer IP, Pixelscan, BrowserLeaks, or another tool may not show exactly the same result.

Focus on the specific signal being flagged rather than trying to make every checker show the same score.

Does a warning mean my account will be restricted?

No.

A warning only means the checker found something it thinks is worth reviewing. It can’t predict how a specific website will evaluate your browser profile or social profile.

When should I contact support?

Contact support if:

• You didn’t customize the flagged setting and the warning keeps appearing
• You can’t tell which signal is causing the mismatch
• The result changed unexpectedly after switching computers

Open the live chat widget in the Multilogin app or on the website, or email [email protected].

Send:

• The checker name
• A screenshot of the result
• Your browser profile ID
• Whether you recently opened the profile on another computer
