Use case

Manage Multiple E-Commerce Stores Safely

Running more than one Amazon, Shopify, eBay or Mercado Livre store means keeping each one's login, cookies and browsing fingerprint independent from the others. Nox Core gives every store its own isolated profile, so managing store #2 never touches store #1's session.

Marketplaces actively look for linked accounts

Amazon's own seller policy explicitly addresses multiple accounts and what counts as a legitimate business reason to run more than one — linked-account detection is a documented, real part of their enforcement.

One browser, one fingerprint, many storefronts

Without isolation, every store you log into from the same browser shares the same cookies, cache and device fingerprint.

Staying compliant matters more than staying hidden

Most marketplaces allow multiple stores under specific conditions (separate legal entities, disclosed relationships, etc.) — the goal is a clean, independent setup per store, not evading a platform's rules.

How it works in Nox Core

  1. 1Create one isolated Nox Core profile per store or seller account.
  2. 2Assign each profile its own SOCKS5 proxy, ideally matching the store's target market.
  3. 3Check the IP quality score before assigning a proxy to a new store.
  4. 4Import or export a store's full profile (cookies, proxy, fingerprint) as one JSON file when you need to move or back it up.

Running multiple e-commerce stores without association

For cross-border sellers, store association (店铺关联) is the most expensive risk there is: platforms like Amazon, eBay, Shopee, Temu and Lazada cross-reference the browser fingerprint, IP address, payment details and login behaviour, and when two storefronts share any of those signals a ban on one can cascade to all of them. Clearing cookies or switching a VPN does not help, because the device fingerprint — Canvas, WebGL, fonts, hardware — stays identical and keeps the accounts linked. The reliable approach is one isolated environment per store, each with its own fingerprint and its own dedicated proxy, kept separate from the very first login.

In Nox Core, every store runs in its own environment with a genuinely distinct fingerprint and a dedicated SOCKS5 proxy, and each proxy is checked with a built-in IP quality score before you rely on it, so you catch a flagged or datacenter IP before it burns a storefront. Keeping the timezone and language consistent with the proxy's location is the detail most sellers miss and the one that most often triggers an 'unusual login' review. Note that a fingerprint browser covers the device and network signals only — it does not address the payment, real-name or listing-quality checks that can also get a store banned, so treat it as one essential layer of a compliant multi-store operation, not the whole solution.

Common questions

Can I legally run multiple Amazon seller accounts?

Amazon's own seller policy allows multiple accounts when there is a legitimate business reason (e.g. separate brands or legal entities) and requires it to be disclosed through their process. Always check the current policy on Seller Central directly — this page is not legal advice.

Does profile isolation replace reading the platform's own rules?

No. Isolated profiles keep each store's browsing environment independent, which is good practice regardless — but they don't override or replace a marketplace's account policies. Compliance is on you, not the browser.

Can I use Nox Core for Shopify and Mercado Livre too?

Yes — the same per-profile isolation works for any storefront platform you manage from a browser, including Shopify, Mercado Livre and eBay.
