How to Bypass Browser Fingerprint Detection in Facebook Ads and TikTok: Account Protection through Anti-Detect Browsers

Browser fingerprint detection is the main reason for bans on multi-accounts in Facebook Ads, Instagram, TikTok, and other platforms. When you work with 10-50 advertising accounts or client profiles, security systems analyze hundreds of parameters of your browser and link all accounts into a single chain. The result is a chain ban of all profiles simultaneously.

In this guide, we will explore how fingerprinting works, which parameters are tracked by platforms, and how to set up protection through anti-detect browsers like Dolphin Anty, AdsPower, Multilogin, and quality proxies. Everything will be explained with practical examples and no fluff.

What is a browser fingerprint and how does it work

A browser fingerprint is a unique set of characteristics of your browser and device that websites collect to identify users without cookies. Even if you use incognito mode, change your IP address through a proxy or VPN, platforms can link your accounts by fingerprint.

When you log into Facebook Ads, Instagram, or TikTok, their security systems collect 100-200 parameters:

• Browser parameters: User-Agent, version, languages, time zone, screen resolution
• Canvas fingerprint: a unique fingerprint of the graphics subsystem
• WebGL fingerprint: characteristics of the graphics card and drivers
• Audio fingerprint: features of the audio subsystem
• Fonts: list of installed system fonts
• Plugins and extensions: installed browser add-ons
• Hardware characteristics: number of CPU cores, memory size, battery
• Behavioral factors: mouse movements, typing speed, click patterns

All these parameters are combined into a unique hash. Even if you change 1-2 parameters, the overall fingerprint remains recognizable. This is why simply changing your IP through a regular proxy does not protect against chain bans — the platform sees that different accounts are accessed from the same device (by fingerprint).

What parameters are tracked by Facebook, TikTok, and Instagram

Different platforms use different fingerprinting methods with varying degrees of aggressiveness. Here’s what the main platforms for arbitrage and SMM track:

Facebook Ads and Instagram

Meta (Facebook/Instagram) uses the most advanced fingerprinting system among all platforms. They collect:

Facebook also actively uses behavioral analysis: how you move the mouse, how fast you scroll through the feed, how you fill out forms. If behavior patterns are identical across different accounts, it is an additional signal for linking profiles.

TikTok Ads

TikTok uses similar methods but focuses on mobile parameters (even if you are working from a desktop). Features include:

• Device fingerprint: TikTok tries to identify the actual device, not just the browser
• Emulation of mobile characteristics: if you are working with the ad cabinet from a desktop but emulating a mobile device — this must be consistent
• Sensors API: tracking accelerometer, gyroscope (important for mobile fingerprints)
• Battery API: battery level as an element of fingerprint

Google Ads and YouTube

Google uses less aggressive fingerprinting for advertising accounts but actively tracks inconsistencies between the IP address and browser parameters. For example, if your IP is from Moscow, but the browser's time zone is Vladivostok, this is a red flag. Google also analyzes cookie history and links accounts through Google Account ID.

Anti-Detect Browsers: How They Spoof Fingerprints

An anti-detect browser is specialized software that allows you to create isolated profiles with unique fingerprints. Each profile has its own set of browser parameters, cookies, local storage, and appears as a completely separate device.

The main anti-detect browsers for arbitrage and SMM include:

How an anti-detect browser spoofs fingerprints

When you create a new profile in Dolphin Anty or AdsPower, the browser:

1. Generates a unique set of parameters: User-Agent, screen resolution, languages, time zone, font list
2. Replaces Canvas fingerprint: alters rendering algorithms so that each profile generates a unique hash
3. Emulates WebGL: substitutes parameters of the real graphics card (e.g., NVIDIA GeForce GTX 1060) with slight variations
4. Changes Audio context: each profile returns a unique audio fingerprint
5. Manages cookies and storage: complete data isolation between profiles
6. Controls WebRTC: prevents leaking the real IP address

It is critically important: all profile parameters must be consistent. For example, if you are emulating Windows 10 with a resolution of 1920x1080, then the User-Agent, font list, and WebGL parameters must match a real Windows 10. Inconsistencies (e.g., macOS fonts in a Windows User-Agent) are instantly detected by platforms.

Setting Up Dolphin Anty for Fingerprinting Protection

Dolphin Anty is the most popular anti-detect browser among Facebook Ads and TikTok Ads arbitrage specialists. It offers 10 free profiles and handles bypassing fingerprint detection well. Step-by-step setup:

Step 1: Create a New Profile

1. Open Dolphin Anty → click "Create Profile"
2. Specify the profile name (e.g., "FB Ads - Account 1")
3. In the "Basic Settings" section, select:
   • Platform: Windows (most common for Facebook Ads)
   • User-Agent: leave "Auto" — Dolphin will select a realistic one
   • WebRTC: "Modified" (mandatory to prevent leaking the real IP)

Step 2: Set Up Proxies

Each profile requires a separate proxy server. Dolphin supports HTTP, SOCKS5, and SSH tunnels.

1. In the profile settings, go to the "Proxy" section
2. Select the proxy type:
   • For Facebook Ads: residential proxies or mobile proxies
   • For TikTok Ads: only mobile proxies (preferably 4G/5G)
   • For Google Ads: quality residential proxies will suffice
3. Enter the proxy details:
   • IP address or host
   • Port
   • Username and password (if authentication is required)
4. Click "Check Proxy" — Dolphin will show the IP, geolocation, and proxy type
5. Ensure that the geolocation of the proxy matches the time zone of the profile (more on this below)

Step 3: Aligning Geolocation and Parameters

The most common reason for detection is inconsistency between the proxy's IP address and the browser parameters.

1. Check the geolocation of the proxy (city and country)
2. In the profile settings → "Geolocation":
   • Set the "Allow" mode
   • Specify coordinates corresponding to the proxy's city (can be found via Google Maps)
   • Accuracy: ±1-2 km from the city center
3. In the "Time Zone" section:
   • Select the time zone of the proxy's city
   • Do not use "Auto" — this may cause inconsistencies
4. In the "Languages" section:
   • Set the primary language of the proxy's country
   • For the USA: English (United States)
   • For Russia: Russian (Russia)

Example of correct setup: Proxy from London → Time Zone GMT+0 (Europe/London) → Geolocation 51.5074, -0.1278 → Language English (United Kingdom).

Step 4: Setting Up Canvas and WebGL

Dolphin Anty automatically generates unique Canvas and WebGL fingerprints, but there are nuances:

1. In the profile settings → "Canvas":
   • Mode: "Noise" (adds random changes to rendering)
   • Do not use "Block" — this is detected as an anomaly
2. In the "WebGL" section:
   • Mode: "Noise"
   • Dolphin will substitute parameters of the real graphics card
   • You can manually select a GPU model (e.g., NVIDIA GeForce GTX 1650)
3. In the "WebGL Metadata" section:
   • Vendor: for example, "Google Inc. (NVIDIA)"
   • Renderer: for example, "ANGLE (NVIDIA GeForce GTX 1650 Direct3D11)"

Step 5: Additional Parameters for Facebook Ads

For working with Facebook Ads, it is recommended to enable additional protections:

• Font fingerprint: "Noise" mode — adds variations to the font list
• Audio context: "Noise" mode — makes the audio fingerprint unique
• Media Devices: emulate realistic devices (webcam, microphone)
• Client Rects: "Noise" mode — alters the sizes of DOM elements
• Do Not Track: leave it off (enabled DNT is rare and may be a signal)

After setup, save the profile and launch it. Check the fingerprint through services like pixelscan.net or browserleaks.com — make sure all parameters look realistic and consistent.

Setting Up AdsPower: Step-by-Step Guide

AdsPower is an excellent choice for e-commerce (working with marketplaces) and SMM (managing multiple Instagram, TikTok accounts). It offers powerful automation and API for scripts. The setup is similar to Dolphin, but with some differences:

Creating a Profile in AdsPower

1. Open AdsPower → click "New Profile"
2. Select "Quick Setup" for automatic parameter generation or "Custom Setup" for manual configuration
3. Specify:
   • Profile Name: for example, "Instagram Client 1"
   • Platform: select the operating system (Windows/macOS/Linux)
   • Browser Core: Chromium or Firefox (for Instagram, Chromium is better)

Setting Up Proxies in AdsPower

1. In the profile settings, go to "Proxy Settings"
2. Select the type:
   • HTTP/HTTPS — for most tasks
   • SOCKS5 — for TikTok and Instagram (better compatibility)
3. Enter the proxy details and click "Check Proxy"
4. AdsPower will show the IP, country, city, provider — check that it is a residential or mobile proxy, not a data center

Aligning Parameters

AdsPower has an "Automatic Configuration" feature that automatically selects the time zone, language, and geolocation based on the proxy's IP. This is convenient, but always check the result:

1. After adding the proxy, click "Auto Fill" in the "Environment Settings" section
2. AdsPower will automatically set:
   • Timezone
   • Language
   • Geolocation
   • WebRTC (local IP will be replaced with the proxy IP)
3. Check each parameter manually — sometimes the automation makes mistakes

Setting Up Fingerprint in AdsPower

AdsPower offers three fingerprint modes:

For most tasks, the "Noise" mode is recommended:

1. In the profile settings → "Fingerprint Settings"
2. Canvas: select "Noise"
3. WebGL: select "Noise"
4. Audio Context: select "Noise"
5. Font: select "Noise" (AdsPower will add variations to the font list)
6. Screen Resolution: can leave it automatic or select a popular resolution (1920x1080, 1366x768)

Additional Settings for Instagram and TikTok

When working with Instagram and TikTok, it is important to emulate mobile characteristics, even if you are working from a desktop:

• User-Agent: use a mobile User-Agent (e.g., iPhone or Android)
• Screen Resolution: select a mobile resolution (375x667 for iPhone, 360x640 for Android)
• Device Pixel Ratio: set to 2 or 3 (typical for mobile screens)
• Touch Support: enable emulation of touch events
• Hardware Concurrency: set to 4-8 cores (typical for mobile processors)

AdsPower has ready-made presets for popular devices: iPhone 12, Samsung Galaxy S21, iPad Pro, and others. Use them for quick setup.

The Role of Proxies in Bypassing Fingerprint Detection

Even a perfectly configured anti-detect browser will not protect against bans if you are using the wrong proxies. The IP address is the first parameter that platforms check, and it must be consistent with all other fingerprint parameters.

Which Proxies are NOT Suitable for Bypassing Fingerprinting

Which Proxies are Suitable for Bypassing Fingerprinting

For reliable protection against detection, use:

• Residential Proxies: IPs of real home users, look natural for Facebook Ads, Google Ads, Instagram. Low fraud score, but it is important to take private ones (not from shared pools).
• Mobile Proxies: IPs of mobile operators (4G/5G), ideal for TikTok Ads, Instagram, mobile arbitrage. Lowest risk of bans, but more expensive than residential.
• Private ISP Proxies: a hybrid of data center and residential, good speed and stability. Suitable for Google Ads, e-commerce, scraping.

Requirements for Proxies to Bypass Fingerprinting

1. One proxy = one profile: never use one IP for multiple accounts
2. Static IP: for farming Facebook Ads accounts, use static residential proxies (IP does not change). Rotation is suitable only for scraping.
3. Clean Reputation: check the fraud score through scamalytics.com or ipqualityscore.com — it should be less than 30%
4. Geographic Compliance: if you are driving traffic to the USA, use proxies from the USA (preferably from the same state as the target audience)
5. Stability: the proxy must work 24/7 without interruptions — frequent reconnections raise suspicions

Setting Up WebRTC to Prevent IP Leaks

WebRTC is a technology for video/audio communication in the browser that can reveal your real IP address even when using proxies. Be sure to set up protection:

1. In Dolphin Anty: WebRTC → mode "Modified" (the browser will substitute the proxy IP)
2. In AdsPower: WebRTC → mode "Alter" (similarly)
3. Check for leaks via browserleaks.com/webrtc — only the proxy IP should be displayed

Never use the "Block" mode for WebRTC — this is a rare configuration that itself is a signal for detection systems.

Common Mistakes That Lead to Detection

Even when using anti-detect browsers and quality proxies, many get banned due to errors in configuration or behavior. Let's discuss the most common ones:

Mistake 1: Inconsistency of Parameters

The most common reason for detection is when browser parameters do not match each other or the IP address.

Solution: Always check the profile through pixelscan.net before starting work. The service will show all inconsistencies and evaluate the realism of the fingerprint.

Mistake 2: Using One Proxy for Multiple Profiles

Even if you have 10 profiles with different fingerprints, if they all log in from one IP — Facebook and TikTok will link them instantly.

Solution: The rule "1 profile = 1 proxy" without exceptions. If you have 20 Facebook Ads accounts — you need 20 different proxies.

Mistake 3: Frequent IP Changes (Rotation) for Accounts

Rotating proxies are suitable for scraping but not for working with accounts. If you logged into Facebook Ads today with an IP...
