Our TCP Fingerprint Spoofing tool allows you to mask your device so that the proxy and OS look like a match to online services that are starting to look at additional fingerprints outside of browser/user-agent fields. Internally, we use https://mobilehop.com/fp to check that the fingerprint and OS match. Note that TCP Fingerprint Spoofing only works over HTTP or Socks5 connections in Verizon locations; it does not work over VPN connections or in AT&T locations.
From your proxy license page, you will see a TCP Fingerprint Spoofing bar where you can set your TCP Fingerprint as a Linux/Android or macOS/iOS or Windows device.
When your TCP Fingerprint is set, you will see a message letting you know the fingerprint was applied with the OS of your choosing.
Note: The TCP Fingerprint tool requires our V3 proxy image. If the V3 image is not installed you will see the following response:
If you ever see this response, contact our help desk through the chat bubble and paste a screenshot of the error into chat, and one of our engineers will update your proxy to the latest version. This takes around 10 minutes on average.
