How to Bypass Canvas and WebGL Fingerprinting When Working with Facebook Ads and Instagram: A Complete Guide for Multi-Accounting 2025

If you work with multiple Facebook ad accounts, manage 20+ Instagram profiles for clients, or engage in traffic arbitrage, you have likely encountered sudden account bans. Even when using different proxies and anti-detect browsers, platforms manage to link your accounts and block them in batches. The reason is Canvas and WebGL fingerprinting, browser fingerprinting technologies that allow Facebook, Instagram, TikTok, and other platforms to identify you even when changing your IP address.

In this guide, we will explore what Canvas and WebGL fingerprinting are, how social networks and advertising platforms use these technologies to detect multi-accounts, and most importantly, how to properly configure anti-detect browsers Dolphin Anty, AdsPower, Multilogin, and GoLogin so that each of your profiles appears as a separate unique device.

What is Canvas and WebGL Fingerprinting and Why is it Important for Multi-Accounting

Canvas and WebGL fingerprinting are methods for creating a unique digital fingerprint of your browser and device. Unlike cookies, which can be easily deleted, or an IP address, which can be changed via a proxy, a fingerprint is formed based on the technical characteristics of your hardware and software.

Canvas fingerprinting works as follows: when you open a Facebook or Instagram page, the browser is instructed in the background to draw an invisible image using the HTML5 Canvas API. This image contains text in different fonts, geometric shapes, and gradients. Due to differences in graphics cards, drivers, operating systems, and font smoothing settings, each device draws this image slightly differently. The image is then converted into a hash — a unique string of characters that becomes your "fingerprint."

WebGL fingerprinting uses a similar principle but works with 3D graphics through the WebGL API. The browser renders a three-dimensional scene, and the specifics of graphics processing (GPU model, drivers, supported extensions) create a unique pattern. The combination of the manufacturer and model of the graphics card, driver version, and the set of supported features creates such a specific fingerprint that the probability of a match between two random users is extremely low.

For SMM specialists managing dozens of client Instagram accounts, the situation is even more critical. Instagram actively uses fingerprinting to combat automation and mass following. If the platform detects that 30 different accounts are logging in with the same digital fingerprint, it will consider this suspicious activity and may block all profiles simultaneously.

In addition to Canvas and WebGL, platforms collect dozens of other parameters: screen resolution, time zone, installed fonts, browser languages, audio context, battery parameters (for mobile devices), and much more. However, it is Canvas and WebGL that provide the most stable and unique fingerprint that is difficult to spoof without specialized tools.

How Facebook, Instagram, and TikTok Use Fingerprinting for Detection

Major platforms do not rely on a single detection method — they use a comprehensive approach where fingerprinting plays a key role in the risk assessment system. Let's break down how detection works using the main platforms for arbitrage and SMM as examples.

Facebook and Facebook Ads

Facebook collects fingerprints every time you log into your account and every time you create an ad account. The system analyzes hundreds of parameters and creates a "device profile." If you create a new ad account and its fingerprint matches 95%+ with an already banned account, the new account will be banned even before the first campaign launches — this is called preemptive blocking.

This is especially critical for arbitrageurs working with gray or black verticals. Facebook maintains a database of fingerprints of violators, and if your new account "lights up" with a fingerprint that was previously used for prohibited offers, you won't even be able to pass ad moderation.

Instagram

Instagram (owned by Meta, like Facebook) uses a similar system but focuses on behavioral patterns. The platform not only records your fingerprint but also tracks how you interact with the interface: scrolling speed, click patterns, time between actions. If 10 accounts have the same Canvas fingerprint AND exhibit similar behavior (for example, mass following at the same time), Instagram classifies them as bots.

For SMM agencies, this means that it is not enough to just use different proxies — you need to ensure the uniqueness of the fingerprint for each client account and vary the working patterns.

TikTok and TikTok Ads

TikTok is considered one of the most aggressive platforms in terms of detection. In addition to standard Canvas and WebGL fingerprinting, TikTok analyzes device sensor parameters (accelerometer, gyroscope — relevant for the mobile version), swipe patterns, and even micro-movements of the mouse cursor. The platform uses machine learning to detect anomalies.

When working with TikTok Ads, it is critically important to use mobile proxies in conjunction with anti-detect browsers configured to emulate mobile devices and to ensure the uniqueness of the WebGL fingerprint corresponding to the declared phone model.

As seen from the table, Canvas and WebGL fingerprinting have the highest priority in the detection system. Even if you have correctly spoofed the User Agent, time zone, and screen resolution, but left the same Canvas fingerprint on all accounts — the platform will link them together.

Which Anti-Detect Browsers Effectively Spoof Canvas and WebGL

Anti-detect browsers are specialized programs that allow you to create isolated browser profiles with unique fingerprints. Each profile appears as a separate device with its own hardware characteristics, operating system, and settings. Let's look at the most popular solutions for working with multi-accounts.

Dolphin Anty

Dolphin Anty is one of the most popular anti-detect browsers among arbitrageurs in Russia and the CIS. The main advantage is a free plan for 10 profiles, which is perfect for beginners. Dolphin uses the Chromium core and offers an advanced system for spoofing Canvas and WebGL fingerprints.

Features of working with fingerprinting in Dolphin:

• Automatic generation of a unique Canvas fingerprint for each profile
• Spoofing WebGL parameters by emulating real GPUs (NVIDIA, AMD, Intel)
• "Noise" mode — adding noise to the Canvas so that a new hash is generated each time
• Synchronization of fingerprint with User Agent and screen resolution for consistency
• Ability to import ready-made fingerprints from a database of real devices

Dolphin Anty is excellent for working with Facebook Ads, Instagram, TikTok, and other platforms with strict detection. The browser is regularly updated, closing new detection vectors.

AdsPower

AdsPower is a Chinese anti-detect browser with a strong focus on working with e-commerce platforms (Amazon, eBay, AliExpress) and Asian social networks, but it also performs well with Facebook/Instagram. The browser offers both a free plan (2 profiles) and affordable paid plans.

Advantages of AdsPower for bypassing fingerprinting:

• A library of thousands of real fingerprints collected from live devices
• "Fingerprint Defender" system — automatic uniqueness check of the fingerprint
• Advanced emulation of mobile devices with spoofing of touch events

Setting Up Canvas and WebGL Fingerprinting in Dolphin Anty

Let's go through the step-by-step setup of fingerprinting in Dolphin Anty for creating a profile for a Facebook Ads account. This guide is suitable for both beginners and experienced arbitrageurs looking to optimize their settings.

Step 1: Creating a New Profile

Open Dolphin Anty and click the "Create Profile" button in the upper left corner. You will see a window with many settings. Don't be intimidated — most parameters can be left in "Auto" mode, but for maximum protection, we will go through the key settings.

Basic Settings:

• Profile Name: Give it a clear name, for example, "FB Ads — Account 1 — US Real Estate"
• Folder: Create folders by verticals or geo for convenience
• Tags: Add tags for quick search (e.g., "USA", "active", "creative-test")

Step 2: Configuring Fingerprint

This is the most important section. Go to the "Fingerprint" tab in the profile creation window.

Operating System:

• For Facebook Ads, Windows 10 or macOS is recommended — these are the most common OS among advertisers
• If working with mobile traffic or TikTok — choose Android or iOS
• Important: The OS must match your proxy. If you are using a mobile proxy — choose a mobile OS

Screen Resolution:

• Do not set exotic resolutions — choose popular ones: 1920x1080, 1366x768, 1440x900
• The resolution should match the chosen OS (for macOS, 2560x1600 or 1440x900 is logical)
• Avoid resolutions that do not correspond to real monitors

Step 3: Canvas Settings

In the Canvas section, you will see several operating modes:

• Off: Canvas is not spoofed — DO NOT use this mode!
• Noise: Noise is added to the Canvas, generating a new fingerprint each time
• Block: Canvas API is completely blocked — may raise suspicions
• Real: Uses a real Canvas from the database — recommended option

Step 4: WebGL Settings

WebGL is the second critically important parameter. Dolphin Anty offers the following options:

• WebGL Vendor: Choose from a list of real manufacturers — NVIDIA, AMD, Intel. For Windows profiles, it makes sense to choose NVIDIA GeForce or AMD Radeon; for macOS — Intel Iris or AMD Radeon Pro
• WebGL Renderer: Choose common models. For NVIDIA, this could be GeForce GTX 1060, RTX 2060; for AMD — Radeon RX 580
• WebGL Metadata Mode: Set to "Mask" — this will spoof WebGL metadata while keeping WebGL applications functional

Critically Important: WebGL parameters must be consistent with the rest of the fingerprint. If you chose macOS but specified NVIDIA GeForce — this is a red flag for detection systems, as NVIDIA GPUs have not been used in Macs since 2016.

Step 5: Additional Fingerprint Parameters

In addition to Canvas and WebGL, configure the following parameters for comprehensive protection:

• User Agent: Dolphin will automatically generate a User Agent corresponding to the chosen OS and browser. Do not change it manually unless necessary
• Fonts: "Enable" mode — the browser will spoof the list of installed fonts according to the OS
• Geolocation: Specify a geolocation that corresponds to your proxy. If the proxy is from New York — set the coordinates for New York
• Timezone: The time zone MUST match the geolocation of the proxy
• Language: For the USA, set "en-US"; for the UK, "en-GB", etc.
• CPU Cores: Number of processor cores. For realism, choose 4, 6, or 8 cores
• Memory (RAM): Amount of RAM. Optimal is 8 GB or 16 GB

Step 6: Proxy Configuration

Go to the "Proxy" tab. Here you will bind the proxy to the profile. For Facebook Ads, it is recommended to use residential proxies or mobile proxies.

Enter the proxy details in the format: host:port:username:password

Click "Check Proxy" — Dolphin will check the functionality and show the IP address, country, and city. Make sure that the geolocation of the proxy corresponds to the Timezone and Geolocation settings in the fingerprint.

Step 7: Saving and Launching the Profile

Click "Create" to save the profile. Now you can launch it by clicking the "Start" button. A browser will open with a unique fingerprint, fully isolated from your main system and other profiles.

Before starting work with Facebook Ads, be sure to check the fingerprint through specialized services (more on this in the "Checking Fingerprint" section).

Configuring Fingerprinting in AdsPower

AdsPower offers a slightly different approach to setting up fingerprints, focusing on using ready-made profiles from a database of real devices. This is especially convenient for those who do not want to delve into technical details and prefer automation.

Creating a Profile in AdsPower

Click "New Profile" in the main AdsPower window. You will see two profile creation modes:

• Quick Setup: AdsPower will automatically generate all fingerprint parameters
• Advanced Setup: Manual configuration of all parameters

For beginners, Quick Setup is recommended; for experienced users, Advanced.

Quick Setup Mode

In Quick Setup mode, you only need to specify:

• Platform: Choose Facebook, Instagram, TikTok, or another platform — AdsPower will optimize the fingerprint for the selected site
• Country: Specify the country of your proxy — the system will select the corresponding language, time zone, and popular device configurations for that region
• Device Type: Desktop or Mobile

AdsPower will automatically generate the Canvas and WebGL fingerprint from its database of real devices. This is very convenient and safe, as you get a fingerprint that 100% corresponds to a real user from the selected country.

Advanced Setup Mode — Canvas Configuration

If you chose the advanced mode, go to the "Basic Settings" → "Canvas" section.

Available Canvas Modes in AdsPower:

• Off: Disabled (not recommended)
• Noise: Adding noise to the Canvas
• Custom: Using a custom Canvas from the database

The "Custom" mode is recommended — click the "Random" button next to this option, and AdsPower will select a random Canvas fingerprint from the database of real devices that matches your OS and browser settings.

Configuring WebGL in AdsPower

In the "WebGL" section, you can configure:

• WebGL Image: Mode for spoofing WebGL images (analogous to Canvas for 3D)
• WebGL Metadata: Spoofing GPU information
• Vendor: Choose the graphics card manufacturer (select from the list of real ones)
• Renderer: GPU model (must match Vendor)

AdsPower has a convenient "Auto-match" feature — when activated, the system will automatically select WebGL parameters that correspond to the chosen operating system and other fingerprint components.

Fingerprint Defender — Unique Feature of AdsPower

After creating the profile, right-click on the profile and select "Check Fingerprint" → "Fingerprint Defender." A built-in analyzer will open, showing:

• The uniqueness of your fingerprint (in percentage)
• Consistency of parameters (whether there are contradictions between OS, GPU, screen resolution)
• Potential issues (e.g., exotic combinations of parameters)
• Recommendations for improving the fingerprint

This is a very useful tool for checking the quality of the setup before starting work with advertising accounts.

Working with Fingerprints in Multilogin and GoLogin

Multilogin — Professional Approach

Multilogin offers two browser engines, each with its own features for working with fingerprinting:

Mimic Browser (based on Chromium):

• Use for working with platforms based on Chromium detection (Facebook, Google Ads)
• Canvas Defender operates at the Chromium API level, spoofing data before it reaches JavaScript
• WebGL Spoofing uses its own GPU emulation technology
• Support for all modern web technologies and APIs

Stealthfox (based on Firefox):

• Recommended for platforms with particularly strict detection
• Firefox has a different architecture for Canvas and WebGL, making detection more difficult
• Less common among bots, so it raises fewer suspicions
• Some modern web applications may work unstable

Creating a Profile in Multilogin

When creating a new profile in Multilogin, you will see the "Canvas" section with options:

• Real: Using the real Canvas of your computer (not recommended for multi-accounting)
• Noise: Adding noise
• Off: Complete blocking of the Canvas API
