How do you use a fingerprint browser? From install to your first profile
No technical background required. This walks through the real sequence: install the client, create your first profile, attach a proxy, and confirm the configuration took effect. About ten minutes end to end.

Step one: install the client and sign up
Download the Windows client from the official site and install it. The installer is code-signed, so under normal circumstances no extra authorization is needed. On first launch, register with your email and create a team. Your account is automatically granted 10 free windows and 1 member seat, the allowance does not expire, and no credit card is required.
A window here is the browser profile referred to throughout this guide - one window corresponds to one independent runtime environment, which you can think of as a separate virtual computer.
Step two: create your first browser profile
Open Window Management and click New. There are really only three things to fill in: a name that makes the profile easy to identify (a platform-region-number format works well, for example Store-US-01), the target platform and region, and the fingerprint parameters.
By default the system generates a complete, internally consistent set of fingerprint parameters, and beginners can simply accept them. The system makes sure that Canvas, WebGL, fonts, time zone and language never end up in a combination that contradicts itself. If you have specific requirements, you can also adjust each parameter by hand.
- Profile name: use a consistent naming convention so things stay manageable once you have dozens of profiles
- Region and language: pick the market this account actually serves, as it affects the time zone and how pages render
- Fingerprint parameters: the automatic default is fine, with templates covering Windows / macOS / Android / iOS
Step three: bind a proxy IP
Once a profile exists, give it an exit IP. There are two ways to do this: pick a NexIP residential IP and bind it by choosing a country and region, or import your own proxy, with HTTP, HTTPS and SOCKS5 all supported.
If you use your own proxies, bulk-import them in the proxy center and check availability in a single pass rather than testing them one by one. Once bound, the profile's time zone and language align automatically with the location of the exit IP.
Step four: launch and confirm the configuration works
Double-click a profile to start it. The interface is essentially identical to standard Chrome, so you can log in, install extensions and work normally. Login state is stored inside that profile, so closing and reopening it leaves you signed in with no need to log in again.
On your first run it is worth doing a quick self-check: open a public fingerprint testing page and confirm that the exit IP is the one you set, that the time zone matches the IP's location, and that WebRTC is not exposing an address outside the proxy. Log into your real account only once all of that checks out.
What to do next
Once profiles are running, the two features that save the most time day to day are window sync and RPA. The first lets you work in one main window while every other window replicates the same clicks, typing and scrolling in real time. The second records repetitive workflows into reusable tasks you can run on a schedule or in bulk.
If you need to drive things from a script, the client includes a free Local API compatible with Selenium, Puppeteer and Playwright, with no cap on the number of calls.
Frequently asked questions
Do I need to buy a proxy before I can use it?
No. A profile launches perfectly well with no proxy bound, using your local network connection. Proxies come in when you need to differentiate exit IPs, so you can get comfortable creating profiles and using them day to day first, then add proxies later.
Are 10 free windows enough?
For individual sellers and teams just starting out, usually yes - and the allowance does not expire, with no feature tiers attached. When you need more, capacity scales at 0.30 USDT per window per 30 days, billed only on the additional capacity, so your existing free allowance is never charged for twice.
How many profiles can one computer run at the same time?
Mostly it comes down to memory and CPU. Each profile is a separate browser process consuming about as much as one ordinary Chrome window. A typical office machine handles a dozen or so simultaneously without difficulty, and a better-specced machine handles more.
Do my profiles survive a move to a new computer?
Yes. Profile configurations sync to the cloud encrypted, so signing into the same account on a new machine restores all of them, including fingerprint parameters, proxy bindings and group information.
