Beyond incognito: a fingerprint browser that gives every account a durable identity of its own
Closing an incognito window cleans up your machine and nothing else. Canvas, WebGL, fonts, timezone and language still report exactly what your computer really is, while the session you spent weeks warming up is wiped and you start the verification dance again. NexBrowser does the opposite: every account gets its own data directory and its own full set of fingerprint parameters, profiles persist, and reopening one still finds you signed in.

What most people call privacy only hides things from themselves
All four of these happen daily in multi-account work, and they share one trait: your machine looks clean while the website sees everything.
Close the incognito window, lose the login
Incognito only promises that your own machine keeps no history or cookies. Close the window and the sessions you warmed up, the back-office logins and the carts are all gone, so the next visit means codes and two-factor prompts all over again.
A new window is not a new identity
Open two incognito windows on the same machine and the Canvas output, WebGL renderer string, font list and audio signature come back virtually identical. A detection script never has to read a cookie to know it is the same device.
A proxy on its own makes you stand out
The exit IP says Germany while the browser reports UTC+8, a zh-CN locale and a WebRTC leak of the local address. An account whose signals contradict each other draws far more review than one browsing honestly from home.
Account data scattered where anyone can take it
Cookies exported to a text file and passed around chat, passwords in a shared spreadsheet. A lost laptop or a departing teammate takes the whole line of accounts, and afterwards nobody can say who signed in or when.
An incognito window, or a genuinely separate browser identity?
The old way
- Close the incognito window and every cookie and login is gone
- Fingerprint values never change — a new window is not a new identity
- A proxy only swaps the exit IP; local timezone and language still give you away
- Cookies and passwords circulate in documents and chat with no audit trail
With NexBrowser
- Profiles persist — reopen one tomorrow and you are still signed in
- 20+ fingerprint parameters set per profile, with nothing shared between them
- Proxy, timezone, language and WebRTC all line up end to end
- Encrypted locally, synced to the cloud, shared by role without exposing passwords
Full identity isolation, not just cleared traces
From core-level fingerprint to network exit, every account gets what looks like its own device.
20+ fingerprint parameters, set individually
Built on a real Chrome core: Canvas, WebGL, fonts, audio, screen and hardware values generated per profile and kept consistent with one another.
WebRTC, timezone and language aligned
WebRTC follows the proxy exit while timezone, language and geolocation match the IP automatically, leaving no contradictions to spot.
Encrypted locally, synced to the cloud
Cookies, cache and local storage stay encrypted on your machine; profile configuration syncs so any device picks the profile up unchanged.
Logins that stay logged in
Each profile keeps its own session for the long run, so there is no endless re-verification and no re-login tax on your day.
Incognito vs a fingerprint browser: why incognito cannot protect your accounts
Incognito solves one problem: someone else using your computer cannot see where you have been. It keeps history, cookies and form cache in memory and throws them away when the window closes. But websites never identified you by cookies alone. Inside that incognito window, the pixel-level differences in Canvas rendering, the WebGL renderer and driver strings, the installed font list, the AudioContext sampling signature, the screen resolution and the hardware concurrency count are all unchanged — together they form a device fingerprint stable enough to follow you.
So incognito loses twice: barely any extra privacy, and none of the convenience, because the session you invested in disappears with the window. A fingerprint browser inverts the goal. Instead of leaving nothing behind, it lets every account leave behind a consistent trail that belongs only to it. With storage and fingerprint isolated at the same time, keeping a session signed in for months becomes the safe option rather than the risky one.
- Incognito clears local records only — Canvas, WebGL, font and audio values match your everyday browsing
- Several incognito windows on one machine report nearly identical fingerprints
- Every profile gets its own data directory and parameter set, so logins survive for the long term

What fingerprint browser privacy actually does: 20+ parameters, each one separate
When you create a profile, NexBrowser builds a full parameter set for the platform and region you picked: Canvas noise, WebGL renderer and vendor, font list, AudioContext, screen resolution, colour depth, hardware concurrency, device memory, timezone, language, WebRTC policy, User-Agent and engine version. These are not random numbers but values chosen to agree with each other — randomised parameters tend to make a profile unique in a way no real person ever is, and internal consistency is what actually matters.
Underneath sits the storage layer. Every profile keeps its own data directory, so cookies, cache, localStorage and IndexedDB cannot read across profiles, and a tracking identifier written by account A never surfaces on a page opened by account B. Isolating both layers together is what makes a platform see a handful of unrelated devices instead of a handful of tabs on one machine.
- Canvas, WebGL, fonts, audio, screen and hardware values are all editable and testable on a detection site
- Fingerprint templates update from the cloud as the Chrome core moves on — no version chasing
- Cookies, cache, localStorage and IndexedDB are stored per profile and cannot read each other

Where account data lives, and how a team shares it without leaks
Cookies, cache and local storage are encrypted on your own machine, while profile configuration — fingerprint parameters, proxy bindings, group structure — syncs to the cloud in encrypted form. Change computers, reinstall the system or hand an account to a colleague, and signing in restores the profile exactly as it was: the fingerprint does not shift and the session does not have to be rebuilt.
On the team side, roles do the work. You grant a group to the right person and their profiles open already signed in, with the password held by the system and never displayed. There is a record of who opened which profile and when. When someone leaves you revoke access instead of rotating every password — which is precisely the moment credentials are most likely to leak.
- Local data encrypted, profile configuration synced, a new machine restored in one step
- Access granted by role, so teammates never touch the account passwords
- Every action logged, permissions revocable at any time, handovers without password changes

Three steps to a solid privacy foundation
From creating the profile to verifying the fingerprint — all of it visual, with no code involved.
Pick the platform and region when creating a profile and NexBrowser generates a complete, internally consistent fingerprint, with every value editable when you want to fine-tune it.
Bind an HTTP, HTTPS or SOCKS5 proxy so timezone, language and WebRTC follow the exit IP automatically, or pull residential IPs straight from NexIP.
Run a detection site and check the values line up; from then on the identity is reusable for the long term and travels with you to any device.
Fingerprint browser privacy FAQ
How is a fingerprint browser different from incognito mode?
Incognito only avoids saving records on your machine, and closing the window wipes the session while the fingerprint, timezone and language remain those of your real device. A fingerprint browser gives each account a complete, separate browser identity with its own cookies, cache, local storage and proxy. Profiles persist, can be migrated, and never share data with one another.
Are the fingerprints just random fakes? Will that stand out more?
They are not random values thrown together. NexBrowser generates parameter sets on a real Chrome core and keeps all 20+ values internally consistent, so the profile reads as an ordinary, real device. You can also set any parameter by hand and lock the signature of a profile in place instead of wearing a new face on every launch.
Where is my account data stored, and is it safe?
Cookies, cache and local storage are encrypted on your own machine, and profile configuration can sync to the cloud so the same profile works after you switch devices. For teams, profile access is granted by role, so members open an account without ever knowing the password, and every action is recorded in the audit trail.
Can I just use a proxy instead of a fingerprint browser?
A proxy only changes the exit IP — the fingerprint, timezone, language and WebRTC your browser reports are still your own, and the mismatch makes you more visible, not less. NexBrowser aligns all of them with the proxy exit and supports HTTP, HTTPS and SOCKS5 with bulk import, per-profile binding and availability checks, plus NexIP residential addresses.
If I switch computers, do my fingerprints and logins survive?
Yes. Profile configuration syncs to the cloud in encrypted form, so signing in on a new device restores everything with fingerprint parameters, proxy bindings and group structure unchanged. Sessions travel with the profile data, so nothing has to be warmed up again and a teammate taking over reconfigures nothing.
