How to Use BrowserScan to Check Your Browser Fingerprint and Avoid Detection

In today’s digital landscape, websites, advertisers, and platforms have become experts at identifying users online. Even if you change your IP address with a proxy, your browser leaves behind a unique “fingerprint” that can still expose your identity. This fingerprint is made up of dozens of data points—like fonts, screen resolution, WebGL rendering, and time zones—that create a near-unique profile of your device.

That is exactly where BrowserScan comes into play. It is a testing tool designed to reveal whether your IP address is leaking and how identifiable your browser fingerprint really is. This guide explains everything you need to know about BrowserScan in 2026—what it is, how it works, what it tests, how to interpret your results, and how to fix the issues it uncovers.

Part 1: What Is BrowserScan?

BrowserScan is an advanced browser fingerprint analysis tool that examines your browser’s fingerprints and gives you a fingerprint authenticity score. This score is pivotal: a figure below 90% flags potential privacy risks, indicating you may be divulging traces that could be exploited to track your online movements or link your multiple accounts, leading to possible account suspensions.

How BrowserScan Works

BrowserScan works by running a series of tests inside your browser and your network connection. It doesn’t anonymize you on its own—instead, it acts as a diagnostic platform. Its purpose is to show what information your browser and network are exposing whenever you visit a website.

When you run a BrowserScan test, the platform checks:

• Browser attributes – such as user agent, installed fonts, screen resolution, and operating system
• Rendering technologies – WebGL and canvas fingerprinting that generate unique patterns
• Audio and font identifiers – that differ across systems
• IP address data – what the outside world sees when you connect

Put simply, it helps answer the question: How trackable am I?

Why People Use BrowserScan

BrowserScan isn’t just for cybersecurity professionals. A wide range of users benefit from it:

• Privacy-conscious individuals – who want to understand what their browser reveals
• Multi-account managers – who need to verify that each account has a unique, consistent fingerprint
• Web scrapers and automation users – who need to ensure their setup avoids detection
• Anti-detect browser users – who want to confirm their fingerprint spoofing is working

Part 2: What BrowserScan Tests

BrowserScan provides a comprehensive overview of your browser’s profile, listing key elements across several categories.

Overview Section

The initial scan provides a comprehensive overview, listing:

• Browser Type & Version
• Operating System
• Language
• IP Address
• Time Zone
• Postal Code
• Country & Geolocation
• Proxy Status
• DNS Leaks
• Bot Detetion

The BrowserScan overview outlines this information and provides an authenticity score. For example, even the default Brave browser settings, which obfuscate some details by default, get a 95% fingerprint authenticity score—with a -5% deduction for canvas tampering.

WebRTC and DNS Leak Detection

WebRTC is a technology that enables real-time communication directly in web browsers. While it provides useful capabilities, it also poses a risk of WebRTC leaks, which may expose your actual IP address regardless of using a proxy. BrowserScan specifically checks for these WebRTC leaks to confirm that your true location remains concealed.

For example, if you connect to a proxy server but lack WebRTC leak protection, BrowserScan will still see your original IP address. Social networks can use this trick to identify multiple accounts from the same source, bypassing IP address obfuscation.

DNS leaks occur when your device sends queries to your actual ISP’s DNS server instead of the DNS provided by your proxy. Imagine DNS as an internet phone book—whenever you type a website’s name into your browser, it contacts the DNS server to find the IP address for that domain. DNS leaks can reveal your true location to websites, which is a significant privacy concern. BrowserScan checks for these leaks to ensure that your online presence remains secure and private.

Browser Section

The Browser section displays more browser-specific information, like:

• Plugins
• User Agents
• Versions

Hardware Analysis

The hardware section of BrowserScan offers an in-depth look at your device, which is essential for maintaining online anonymity. It can reveal:

• Architecture of your device
• Canvas fingerprints
• WebGL fingerprints
• Number of CPU cores
• Detailed graphics card information

This section is especially important when using anti-detect browsers or virtual machines to simulate another device. An anti-detect browser modifies your user agent and can make your Windows laptop appear as a mobile Android device. However, some websites will identify a fake user agent if it does not simulate hardware details.

Additional Security Tools

Beyond the basics, BrowserScan offers a suite of tools to bolster your online security:

Tool	Purpose
Port Scanner	Identifies open ports on your device that could be exploited by hackers
IP Address Lookup	Provides extensive details about any IP, including its physical location and the browser in use
2FA Authenticator	Strengthens your login processes by generating or verifying security codes
Cookie Converter	Assesses cookie legitimacy and converts them into a usable format
Internet Speed Test	Checks your connection without the need for additional plugins
UserAgent Parse	Decodes the information within your user agent string

Part 3: The Risks of Browser Fingerprinting

Browser fingerprinting is a tracking technique that collects an array of information about the software and hardware characteristics of a device in a bid to identify the user precisely. These data points are collected and combined to create a profile that is as unique as a real fingerprint, making it possible for websites to identify and track you online without the need for cookies.

The Multi-Accounting Risk

Whether in the e-commerce sector, social media platforms, advertising placements, or affiliate marketing, multi-account operations have become a common operational strategy. However, the implementation of this strategy may face a neglected risk: the leakage of browser fingerprints.

If you use the same device and browser while operating multiple accounts, the browser fingerprints of these accounts will be identical. This could attract the attention of the platform, as it may be considered as brushing or fraudulent behavior, leading to account bans.

For example:

• On e-commerce platforms, sellers often create multiple accounts to increase product exposure. If the browser fingerprints of these accounts are the same, they may be recognized as spam accounts.
• On social media platforms, marketers create multiple accounts to promote products. If the browser fingerprints are the same, they may be recognized as fraudulent behavior.

Anti-Detect Browsers Are Not a Panacea

Even though many users have started using fingerprint browsers to mask their real device information, this does not mean that their accounts are completely safe. Due to the different technologies used by different fingerprint browsers, or improper use, personal information may still be leaked, or a false browser fingerprint may be generated. This could lead to the user’s device being marked as suspicious by the website platform, or multiple accounts being marked as associated.

Therefore, when using a fingerprint browser, users need to utilize a tool to:

• Check if their browser fingerprint is authentic
• See if the local real IP address will be leaked
• Compare the fingerprint of the fingerprint browser with the browser fingerprint of the real device
• Compare whether there are many repetitions in the browser fingerprints of different accounts

After confirming the authenticity of the browser fingerprint, it is obviously safer to operate multiple accounts.

• Low authenticity score – Adjust browser settings or use an anti-detect browser

Part 6: How IPFLY Powers Clean BrowserScan Scores

BrowserScan helps you see problems, but the right infrastructure helps you solve them. IPFLY provides the residential proxy infrastructure that enables clean, consistent browser fingerprints and successful BrowserScan tests.

Why Residential Proxies Are Essential for BrowserScan

BrowserScan’s detection mechanisms are specifically designed to identify inconsistencies between your IP and your browser fingerprint. When your IP originates from a datacenter or hosting provider, BrowserScan will flag it immediately. Datacenter IPs are easily identifiable through IP-to-ASN lookups.

The solution is residential proxies. Residential proxies use real IP addresses assigned by Internet Service Providers (ISPs) to actual households. They appear as genuine consumer connections, making them far less likely to trigger detection.

Part 7: Best Practices for Passing BrowserScan

1. Fix the IP First

The most critical step is using a clean residential IP. A residential proxy routes you through real ISP-assigned home addresses, so to BrowserScan you look like an ordinary household user rather than a server in a data center.

2. Ensure Geographic Consistency

Your IP location, timezone, language, and system locale should all align. If your IP says you are in the United States, your timezone should be set to a US timezone and your browser language should be set to English (US).

3. Check for WebRTC Leaks

Prevent WebRTC from exposing your real IP. BrowserScan specifically checks for WebRTC leaks to confirm that your true location remains concealed.

4. Check for DNS Leaks

Ensure your DNS queries are routed through the same infrastructure as your traffic. Professional proxies run proprietary DNS servers to prevent this from happening.

5. Use Consistent Fingerprint Settings Across Sessions

Frequent changes to your IP, timezone, or other settings can raise suspicion. Maintain consistency across sessions for long-term account health.

6. Use an Anti-Detect Browser for Fingerprint Protection

BrowserScan assesses how uniquely identifiable the browser itself is. An anti-detect browser can spoof canvas, WebGL, font lists, and other fingerprinting vectors to present a consistent, realistic fingerprint.

7. Test Before Going Live

BrowserScan is designed to help you test your setup before going live and avoid detection on target websites. Run a scan, fix any issues, and rerun until all checks pass.

BrowserScan as a Diagnostic Tool for Digital Identity

BrowserScan is an invaluable diagnostic tool for anyone who needs to understand what their browser and network environment reveal to the outside world. By testing IP authenticity, DNS configuration, WebRTC exposure, canvas fingerprinting, and system metadata, it provides a comprehensive audit of your digital identity.

Key takeaways:

1. The authenticity score matters – A score below 90% indicates you are leaking information that can be used to follow you online or identify multiple accounts.
2. WebRTC and DNS leaks are common – Even with a proxy, your real IP can be exposed through these channels.
3. Hardware consistency is essential – Anti-detect browsers that don’t simulate hardware details can still be detected.
4. BrowserScan offers more than just fingerprint checking – Additional tools like port scanning and 2FA strengthen your overall security.
5. Test before going live – A quick check on BrowserScan confirms your configurations and proxy tools are active before any other activity online.

For users who need reliable, consistent access to platforms and services, investing in high-quality network infrastructure is essential. IPFLY’s static residential proxies provide the ISP-registered, dedicated IPs that present a clean, trustworthy identity—one that BrowserScan’s detection mechanisms recognize as legitimate consumer traffic.
