Other settings

Configure what your profile reports about its operating system and hardware, and adjust session, display, and browser controls.

Operating system

Controls which operating system the profile reports to websites.

Option	Description
Windows	Reports Windows as the operating system. Recommended for the widest compatibility with websites, since most sites are built and tested against Windows configurations.
macOS	Reports macOS as the operating system. Use this when you want your profile to appear to come from a Mac, and pair it with matching values in Platform (Browser & Navigator) and WebGL vendor/renderer (Hardware) so all three describe the same Mac.
Linux	Reports Linux as the operating system. A stronger fingerprint signal, not recommended for most profiles, since every other setting on the profile needs to look correspondingly unusual to stay consistent.

Hardware concurrency and device memory

Controls the CPU core count and RAM the profile reports to websites.

Setting	Description
Hardware concurrency	Number of logical CPU cores reported by navigator.hardwareConcurrency. Pick a value matching typical consumer hardware (4-16).
Device memory	Amount of RAM in GB reported by navigator.deviceMemory. Chrome limits this value to 1, 2, 4, or 8.

Set hardware concurrency and device memory together so they describe a consistent device. A high core count paired with a low memory value, for example, doesn't represent typical hardware.

Browser language and Do Not Track

Controls the language the profile reports and whether it sends a tracking preference header.

Setting	Description	Recommendation
Browser language	Uses the navigator language for the browser. Disabling this causes the browser to use a different language than navigator.language reported to websites.	Leave on for most profiles, it keeps the reported language consistent with the browser's actual language, the same check that applies to timezone and geolocation. Turn off only to test how a site behaves when these don't match.
Do Not Track	Sends the browser's "Do Not Track" header with every request. Most websites ignore it, and sending it is itself a mildly distinctive signal.	Some real users enable this in their browser, so the option reflects a real configuration. Leave it off by default, since most users don't have it enabled.

Randomize hardware

Regenerates the hardware concurrency and device memory values. Use Randomize hardware when setting up a new profile. Avoid using Randomize hardware on a profile already in active use, a hardware identity that changes between sessions is more identifiable than one that stays stable.

Session and display

Controls how the profile behaves and appears during use, these settings don't affect what websites see.

Setting	Description	Recommendation
Active session lock	Prevents the same profile from being launched in two places at once, protects you from cookie/session conflicts when teammates share an account.	Leave on for most profiles, especially shared ones. Turn off only if your workflow specifically requires running the same profile in two places at once.
Profile name in browser	Displays the profile name in the browser window's title bar so you can tell multiple open profiles apart at a glance.	Worth keeping on if you regularly have several profiles open.
Startup URLs	Opens one or more pages automatically when the browser launches. Enter one URL per line.	Set this if a profile should always land on the same page on launch, for example, the platform you manage through it.

Browser controls

Controls for command-line flags and the Chrome settings UI.

Setting	Description	Recommendation
Browser arguments	Passes extra command-line flags to Chrome when this profile launches, for example --restore-last-session or --start-maximized.	Only add flags you understand, automation-related flags in particular can change browser behavior in detectable ways.
Hide Chrome settings	Suppresses Chrome's built-in settings UI inside the profile so end users can't change browser preferences.	Most useful on shared profiles, it stops a teammate from changing a setting elsewhere that would break the consistency you've configured across the other tabs.

IPhey

Togging this option on applies extra spoofing tweaks targeted at the iphey.com fingerprint test. Useful when you specifically need IPhey to score green.

A green result from iphey is one data point, not a guarantee. Different detection systems check different combinations of signals, so don't treat this as a final verdict on the profile's setup.
