Manage Multiple Ad Accounts Safely
Agencies and media buyers running several Facebook Ads or Google Ads accounts need each one to look like it belongs to a different person on a different device — not like ten tabs open in the same browser. Nox Core gives each ad account its own isolated profile: separate cookies, separate local storage, a unique fingerprint and its own SOCKS5 proxy.
Shared cookies and cache link accounts together
A single browser profile keeps shared cookies, cache and local storage across every tab and account you log into — exactly the kind of overlap ad platforms' own fraud systems are built to notice.
One fingerprint, many accounts
Canvas, WebGL and audio fingerprinting can tie separate accounts back to the same physical device even when cookies are cleared between sessions.
Shared IP across accounts
Logging into multiple ad accounts from the same residential or office IP, with no proxy separation, adds another visible link between accounts.
How it works in Nox Core
- 1Create one Nox Core profile per ad account, or bulk-create up to 100 at once for larger agencies.
- 2Assign a separate SOCKS5 proxy to each profile so each account connects from its own IP.
- 3Check the built-in IP quality score before you commit a proxy to a client account.
- 4Log into each ad account inside its own profile and keep working — cookies, cache and fingerprint stay isolated per profile.
Keeping multiple ad accounts alive and unlinked
Media buyers running fleets of Facebook and Google ad accounts face the same association risk as sellers, but the stakes per account are higher: a single link between two accounts can burn an entire campaign and the spend behind it overnight. Ad platforms associate accounts through the browser fingerprint, IP, and even shared payment methods or ad creatives. The defensible setup is one isolated environment per ad account, each with a distinct fingerprint and its own dedicated proxy, so the platform's risk control cannot connect them through device or network signals.
With Nox Core, each ad account gets its own environment, unique fingerprint and dedicated SOCKS5 proxy, and the built-in IP quality score (fraud scoring plus RBL and proxy-type detection) flags a bad IP before you attach it to an account rather than after it costs you. Unlimited environments at a flat price mean the cost does not climb as you scale your account fleet, and the built-in RPA engine automates the repetitive setup and warm-up steps across accounts. As always, this covers the device and network layer — account quality, payment consistency and ad-policy compliance remain your responsibility.

Common questions
Can you have multiple ad accounts on Facebook?
Yes — Meta Business Manager supports multiple ad accounts under one business, and agencies commonly manage several on behalf of different clients. Keeping each account's browsing environment separate is a matter of good operational hygiene, not a workaround.
Does Nox Core guarantee my ad accounts won't get flagged?
No. No tool can guarantee that, and we don't claim otherwise. Nox Core isolates cookies, storage, fingerprint and proxy per profile so accounts don't share an obviously identical environment — the platform's own review and compliance rules still apply.
Can I use this for Google Ads too?
Yes — the same per-profile isolation applies to Google Ads accounts or any other ad platform you log into from a Nox Core profile.
