How-to guides and answers for running many accounts
From whether one computer can run multiple accounts to proxy setup, fingerprint parameters and profile migration. These questions get asked daily and the answers are scattered everywhere. Here they are organized into six categories, each written as steps you can follow and verify.

The six categories below follow the path most teams actually take: get the tool working, then get the network layer right, then understand what platforms are really looking at, and only then move on to platform tactics and tool selection. Guides that are written link straight through; categories still in progress point to the closest existing pages.
Getting started: how to use a fingerprint browser and build your first profile
What stalls newcomers is never the feature list. It is not knowing which fields in the new-profile form actually matter, whether a proxy is needed yet, and how to tell whether the configuration took effect at all. This category follows the real operating sequence, so one pass gets your first profile running.
Proxies: how to configure a proxy IP and what to do when it will not connect
Proxies are where multi-account work stalls most often. Fields in the wrong order, the wrong protocol, a missing whitelist entry, and all the browser gives you is one vague error line. This category covers protocols versus IP sources, the exact format to enter, and the order to troubleshoot in.
Account linkage: will multiple accounts on one computer get linked?
This is the most asked question in the category and the one most often half-answered. Linkage is not a switch. It is a probability judgment built from hardware and network signals, browser fingerprints, identity details, business data and behavioral rhythm. These guides break down what platforms really look at, including the parts no tool can fix.
Fingerprinting: what a browser fingerprint is and what it records
Why do sites still recognize you after clearing cookies, opening incognito and switching accounts? Because what identifies you is not the cookie, it is the combination of Canvas, WebGL, fonts, time zone and resolution. Understanding this layer is what makes every later configuration decision make sense, including why changing the UserAgent alone achieves nothing.
Platform tactics: Amazon, TikTok and Facebook multi-account work
Risk controls differ sharply by platform. Amazon weighs payment and registration details, TikTok weighs device signals and behavioral rhythm, and Facebook ad accounts are more sensitive to payment methods and page history. Platform-specific guides are still being written; until then, each solution page already documents that platform signals and how to plan profiles around them.
Choosing a tool: which fingerprint browser, and is the free plan enough?
Selection guides go wrong when they only compare price. What matters is whether the free tier strips features, whether billing counts windows or profiles, whether extra seats cost extra, how many fingerprint parameters are adjustable, and whether the API is free. A dedicated selection guide is in progress; for now the comparison and pricing pages carry the side-by-side tables.
Questions about these guides
I am new to fingerprint browsers. Which guide should I read first?
Start with the NexBrowser beginner tutorial. It walks install, profile creation, proxy binding and the pre-launch checks in order, so your first profile is running in about ten minutes. Then read the proxy setup guide for the network layer, and finally the account association guide to understand what platforms weigh.
Do these guides only apply to NexBrowser?
The principles are universal. What a fingerprint is, why accounts get linked, how proxy strings are formatted and the order to troubleshoot in all hold in any fingerprint browser. Steps that reference a specific screen, such as window management or the proxy center, describe the NexBrowser Windows client.
How often are the guides updated?
Every article shows its last updated date at the top. Platform risk rules and browser engines both keep moving, so we revise the affected sections when product features change or a platform visibly shifts its rules, rather than refreshing dates on a fixed schedule.
Do the steps in these guides work on a Mac?
The NexBrowser client is Windows only for now and a macOS build is still in development, so any step that references the client interface (creating a profile, the proxy center, bulk import) assumes Windows. Everything else is operating-system independent: what a fingerprint is made of, how the four-field proxy format is entered, the order to troubleshoot a dead proxy in, and which layers platforms weigh when deciding that accounts are linked. The self-audit routines on checking sites apply the same way.
What if my question is not answered here?
Each feature and solution page carries FAQs specific to that topic, often more detailed than the guides. If you still cannot find an answer, reach us by Telegram or email from the contact page; during working hours we usually reply the same day.
