Antidetect browser + mobile proxy: full setup (Multilogin, GoLogin, Dolphin)

You bought an antidetect browser, built a clean fingerprint, and the account still got flagged. I see this constantly. The browser is only half the disguise. The other half is the ip sitting behind it, and if that ip is wrong, the best fingerprint in the world won’t save you.

This is the full setup for pairing an antidetect browser mobile proxy combo the right way. The steps are nearly identical in Multilogin, GoLogin, and Dolphin Anty, so once you understand the flow you can do it in any of them.

What an antidetect browser actually does

An antidetect browser isolates fingerprints. Each profile you create gets its own canvas, fonts, screen size, hardware hints, timezone, and storage, sealed off from every other profile. To a website, each profile looks like a different device.

That’s the whole trick. A normal browser leaks one consistent fingerprint across every tab, so ten accounts in one browser look like ten accounts on one machine. An antidetect browser gives each account a separate, believable device.

But a device has to connect from somewhere. That somewhere is the ip, and the antidetect browser doesn’t give you one. That’s the half people forget.

Why a datacenter ip ruins a good fingerprint

Say you build a perfect Singapore phone profile. Mobile screen size, mobile user agent, the right fonts, Singapore timezone. Then you route it through a datacenter proxy.

Now the profile contradicts itself. The fingerprint says phone in Singapore. The ip’s asn says server farm in some other country. Platforms read the asn on every connection, and a phone fingerprint coming out of a data center is a mismatch they catch immediately.

A real mobile ip looks like a person on a Singapore carrier instead, which is the whole reason mobile proxies exist. If the foundation is new to you, what is a mobile proxy lays it out. The short version: the fingerprint and the ip have to tell the same story.

The universal setup flow

Here’s the part that’s the same in all three tools. The labels move around, the steps don’t.

Create a new profile or browser.
Open that profile’s proxy settings.
Pick the protocol: http or socks5.
Paste the host, the port, the username, and the password.
Save, then test the ip from inside the profile.

In Multilogin it’s under the proxy section of the profile editor. In GoLogin it’s the proxy field when you create the profile. In Dolphin Anty it’s the proxy block on the new profile screen. Four fields and one protocol choice, every time.

The test step is not optional. Open the profile and visit an ip check page. Confirm it shows a Singapore carrier ip before you log into anything. If it shows your home ip or the wrong country, the proxy isn’t applied and you stop right there.

http or socks5, and why socks5h matters

For most browser work http is fine. socks5 is lower level and a bit more flexible. The detail that matters is dns.

If you use plain socks5, your machine can still resolve domain names locally, which leaks your real location even though your traffic goes through the proxy. The fix is socks5h. The h means dns resolves through the tunnel, so the lookup happens at the proxy’s end, not yours. If your tool supports it, use socks5h. No leak out the side door.

One clean line per profile

This is the rule that keeps profiles separate: one clean ip line per identity.

If two profiles share the same ip, they’re linked. You can have flawless fingerprints on both, but they came out of the same address, so the platform treats them as one operator with two accounts. The fingerprint isolation you paid for is undone by a shared ip.

The entire approach to running multiple accounts without bans depends on this separation. One profile, one line. Never share.

Sticky session so the ip stays stable

A profile is supposed to be one consistent person. A person doesn’t appear in a new city every time they log in.

So set a sticky session. Sticky means the profile keeps the same ip across days, instead of rotating to a fresh one on a timer. Stable identity, stable ip. If a profile’s address jumps around every session, that instability is itself a flag. Save the rotation for tasks that actually want a fresh ip each time, not for an account you’re trying to keep alive.

Match the timezone, locale, and language

The antidetect browser lets you set timezone, locale, and language per profile. Set them to match the ip.

If the ip is Singapore, the profile should be Singapore timezone, English, with a Singapore locale. A profile claiming to be in Singapore while its browser clock reads a different timezone is a contradiction, and contradictions are exactly what detection looks for. Good antidetect tools can auto-match these to the proxy ip. Let them, and double check it took.

Verify no webrtc or dns leak

Before you log into a single account, run a leak test from inside the profile.

webrtc can expose your real ip even when the proxy is working, because it uses a separate channel. Every serious antidetect browser has a webrtc setting. Set it to mask or route through the proxy, then test. Check dns too, on the same leak page. You want the leak test to show only the Singapore proxy ip, nothing from your real connection. Do this once per profile when you set it up. Catching a leak after you’ve logged in is too late.

Common mistakes

The ones that link profiles anyway, in the order I see them:

Reusing one ip across several profiles. The fastest way to link accounts.
Mismatched timezone or locale. A Singapore ip with a foreign browser clock.
Leaving webrtc on. The fingerprint is clean, the real ip leaks anyway.
Using a datacenter ip with a mobile fingerprint. The asn gives it away.
Skipping the ip test, then logging in and finding the proxy never applied.
Copying cookies or storage between profiles, which ties them together no matter how clean the ips are.

None of these are hard to avoid. They just have to be checked every time, per profile.

The honest part

The browser and the proxy are two halves of one disguise. The antidetect browser makes each profile look like a different device. The mobile proxy makes that device look like a real person in Singapore. Get one half right and the other wrong, and the profile contradicts itself and gets caught.

So the setup isn’t really about the browser or the proxy on its own. It’s about making them agree. One clean carrier ip per profile, sticky, timezone matched, no leaks. Do that and the fingerprint you built actually holds up.

If you need the ip half done right, there’s a free trial of Singapore Mobile Proxy, real SG SIMs on Singtel, M1, and StarHub, one clean line per profile, sticky or rotating as you choose. Use code YT30. It’s the half an antidetect browser can’t give you on its own.
