Fingerprint Testing: How to Verify Your Browser Setup

7 min readβ€’May 7, 2026

Why Test Your Fingerprint?

Setting up an antidetect browser profile is just the first step. You need to verify that your fingerprint is actually working correctly. A misconfigured profile can leak your real identity or produce inconsistent data that flags your account.

Important: Always test your fingerprint setup before using a profile for real accounts. A 5-minute test can save you from account bans.


Step-by-Step Testing Workflow

Step 1: Prepare Your Profile

Before testing, make sure your antidetect browser profile is properly configured:

  1. Open your antidetect browser (MoreLogin, AdsPower, GoLogin, etc.)
  2. Create a new profile or select an existing one
  3. Assign a proxy β€” residential proxy recommended for best results
  4. Set the profile timezone and language to match your proxy location
  5. Launch the profile

Step 2: Test with BrowserLeaks

Visit: browserleaks.com

BrowserLeaks is the most comprehensive fingerprint testing suite. Test each section in order:

2a. Canvas Fingerprint β†’ browserleaks.com/canvas

  • Look at the Signature hash β€” it should be unique per profile
  • Open 2 profiles side by side β€” their Canvas hashes should be different
  • If they match, your antidetect browser isn't spoofing Canvas properly
  • Expected result: βœ… Unique hash like 4a8b2c1d9e7f3a5b

2b. WebGL Report β†’ browserleaks.com/webgl

  • Check the Unmasked Renderer field β€” it should show a real GPU model
  • Verify it matches the OS you're spoofing (e.g., no NVIDIA RTX on a "macOS" profile)
  • Expected result: βœ… GPU like ANGLE (NVIDIA, NVIDIA GeForce GTX 1660 SUPER)

2c. WebRTC Leak Test β†’ browserleaks.com/webrtc

  • CRITICAL CHECK β€” WebRTC can expose your real IP even behind a proxy
  • Your real local IP should NOT appear anywhere
  • The public IP should match your proxy IP
  • Expected result: βœ… Only proxy IP shown, no local IP leaks

2d. Font Detection β†’ browserleaks.com/fonts

  • The number and list of fonts should match the spoofed OS
  • Windows profiles should show Windows fonts, macOS profiles should show macOS fonts
  • Expected result: βœ… Font list consistent with the spoofed operating system

2e. Audio Context β†’ browserleaks.com/javascript

  • The AudioContext fingerprint should be unique per profile
  • Expected result: βœ… Unique audio hash

Step 3: Test with CreepJS

Visit: abrahamjuliot.github.io/creepjs

CreepJS is the most advanced detection test. Wait 10-15 seconds for all tests to complete.

What to check:

  • Trust Score β€” higher is better, aim for 70%+
  • Lies Detected β€” should be 0 for best results
  • Fingerprint Grade β€” A or B is good, C or below needs fixing
  • Browser/OS consistency β€” CreepJS checks if all parameters tell a coherent story

How to read results:

  • 🟒 Green items = passing, your fingerprint is good
  • 🟑 Yellow items = suspicious, may need adjustment
  • πŸ”΄ Red items = detected tampering, needs immediate fixing

Common CreepJS warnings and fixes:

  • "Navigator lies detected" β†’ Update your antidetect browser to the latest version
  • "Canvas/WebGL mismatch" β†’ Reset fingerprint settings and regenerate
  • "Timezone inconsistency" β†’ Match timezone to proxy location

Step 4: Test with Pixelscan

Visit: pixelscan.net

Pixelscan provides a quick visual check with clear pass/fail indicators:

Expected results:

  • IP/Timezone β†’ βœ… Match (green)
  • Browser/OS β†’ βœ… Consistent (green)
  • WebRTC β†’ βœ… No Leak (green)
  • Overall Status β†’ βœ… Consistent

If any item shows ❌ (red), refer to the troubleshooting section below.

Step 5: Test with IPHey

Visit: iphey.com

IPHey focuses on IP and browser consistency:

  • Overall Score β€” aim for "Real" or "Good" rating
  • IP Quality β€” check your proxy isn't flagged
  • Browser Fingerprint β€” should show as unique and consistent

Troubleshooting Common Issues

Problem: Same Canvas hash across all profiles

Cause: Canvas spoofing is disabled or using the same seed

Fix: In your antidetect browser settings:

  1. Find the Canvas/Fingerprint section
  2. Set Canvas mode to "Noise" or "Unique per profile"
  3. Regenerate the profile fingerprint
  4. Retest on BrowserLeaks

Problem: WebRTC leaking real IP

Cause: WebRTC protection is not enabled

Fix:

  1. In profile settings, find WebRTC section
  2. Set to "Disabled" or "Proxy Only"
  3. Relaunch the profile
  4. Verify at browserleaks.com/webrtc

Problem: Timezone doesn't match IP location

Cause: Profile timezone not matching proxy location

Fix:

  1. Check your proxy's actual location (e.g., New York)
  2. Set profile timezone to match (America/New_York)
  3. Also update the language (en-US) and geolocation coordinates

Problem: CreepJS shows "Lies detected"

Cause: Fingerprint parameters are inconsistent

Fix:

  1. Don't mix parameters from different OS/browser combinations
  2. Use your antidetect browser's auto-fingerprint feature
  3. Avoid manually overriding individual parameters unless necessary

Problem: Pixelscan shows "Inconsistent"

Cause: One or more parameters don't match each other

Fix:

  1. Check the specific red items in Pixelscan
  2. Most common: timezone/IP mismatch or browser/OS mismatch
  3. Reset the profile and use automatic fingerprint generation

Testing Best Practices

  • Test every new profile before using it for real accounts
  • Test after proxy changes β€” a new proxy might need timezone/language adjustments
  • Test periodically β€” antidetect browser updates can change fingerprint behavior
  • Use multiple test tools β€” no single tool catches everything
  • Compare profiles β€” open 2 profiles side by side and verify they look different
  • Save working configurations β€” once a profile passes all tests, note the settings for future reference
