What antidetect is — and why it always needs its own proxy

An antidetect browser creates many browser profiles, each with its own fingerprint — User-Agent, Canvas, WebGL, fonts, time zone, language — so each account looks like it runs on a different device. But fingerprint is only half the story: if multiple profiles share one IP, platforms still link them. That's why antidetect must always pair with a dedicated clean proxy per profile.

What goes into a browser fingerprint?

User-Agent, screen resolution, Canvas/WebGL hashes, font list, time zone, language, audio context and many more. Combined, they form a near-unique fingerprint — enough to identify you even after clearing cookies and changing IP.

TLS fingerprint (JA3/JA4) — the hidden layer antidetect misses

From the very first TLS handshake, the server already reads the client's JA3/JA4 "signature". Many antidetect tools can't patch this layer, so even a perfect browser fingerprint can leak. Routing through a proxy/router correctly helps reduce anomalous network-layer signals.

5 leaks that expose antidetect profiles anyway

Before blaming the antidetect tool, check the 5 classic leaks: (1) WebRTC exposing your real IP even with a proxy attached — the most common failure; (2) DNS leak — lookups going straight to your real ISP's DNS instead of through the proxy; (3) time zone/language mismatching the IP — a US IP with a GMT+7 clock and vi-VN language is a heavily scored signal; (4) over-faked Canvas/ClientRects/AudioContext — unrealistic noise makes the fingerprint "too unique", easier to spot than no faking at all; (5) a datacenter IP with a high fraud score despite a perfect fingerprint.

Which antidetect? The names Vietnamese users pick

Vietnam's MMO community mostly runs Dolphin Anty (how to attach a proxy), the GoLogin / Multilogin / AdsPower trio (proxy setup guide) and Hidemyacc — an antidetect built by Vietnamese developers. They differ mainly in fingerprint-faking quality (Canvas, WebGL, ClientRects), free-profile count and monthly price. Whichever you pick, the rule never changes: one clean IP per profile — antidetect only splits fingerprints, it can't replace your IP. Rotating 5G mobile IPs are the most common pairing thanks to low fraud scores and unlimited rotation.

Antidetect + proxy + router = the complete stack

Antidetect splits fingerprints; a 5G proxy gives each profile its own clean IP; the router fakes the MAC, syncs DNS/time zone and seals network-layer leaks (WebRTC, LAN scans, tracert) for every device at once. Drop any layer and you leave a linking signal.

Frequently asked questions

Is antidetect different from incognito mode?

Very different. Incognito only avoids saving local history/cookies; your fingerprint and IP still leak. Antidetect fabricates a distinct fingerprint per profile.

Is a proxy mandatory with antidetect?

In practice, yes. If profiles share an IP, platforms link them despite different fingerprints. Each profile needs its own clean IP.

Do 5G proxies fit antidetect?

Very well — clean mobile IPs with a low fraud score and rotation make a common pairing with antidetect for multi-accounting.

What are JA3/JA4?

They are ways to fingerprint a client from its TLS handshake parameters. Platforms use them to detect bots and automation even after IP/User-Agent changes.

How do I know whether my antidetect profile leaks?

Open the profile and run the IP & leak checker: if WebRTC/DNS return an IP different from the proxy, the time zone mismatches the IP's location, or the fraud score is high — the profile leaks and needs a proxy/config fix.
