Undetectable Browser Proxy Setup

Add a dedicated Coronium line to an Undetectable profile, with the Reset Link in the IP Change Link field and the Change IP button doing the rest.

Undetectable is an antidetect browser built on Chromium, with local and cloud profiles. It is one of the few that documents a field for a mobile proxy's IP-change link, which makes a rotating carrier line a two-click job.

Before you start

  • Undetectable on the Chromium engine

    Undetectable also ships an older engine of its own, which it calls deprecated. Create new profiles on Chromium, the default.

  • One line per profile

    Each profile is a separate person to the sites you visit. Give each its own line, so no two profiles share an address or a rotation.

  • The four values and the Reset Link

    Host, port, username and password from Your Proxies, and the Reset Link from the card's IP Rotation block.

Fields to copy from Coronium

In dashboard.coronium.io, open Your Proxies. In Cards view every value on the proxy card copies with a click. In List view the Connection column copies the whole endpoint, login included, in the format picked in the toolbar.

Connection IP
The host your tool connects to.
In Undetectable: The host, in the data field next to the protocol list
HTTP Port
The port for HTTP on that host.
In Undetectable: The port, with the protocol set to HTTP
SOCKS5 Port
The port for SOCKS5 on the same host.
In Undetectable: The port, with the protocol set to SOCKS5
Username
One login for both ports.
In Undetectable: The login, in the same field
Password
The password for that login.
In Undetectable: The password, in the same field
Reset Link
Under IP Rotation on the card (Rotate API link in List view). Opening it changes the IP.
In Undetectable: IP Change Link

Formats Undetectable reads

Host first
CONNECTION_IP:SOCKS5_PORT:USERNAME:PASSWORD
Login after the host
CONNECTION_IP:SOCKS5_PORT@USERNAME:PASSWORD
Login first
USERNAME:PASSWORD@CONNECTION_IP:SOCKS5_PORT

Pair the protocol with its port: the SOCKS5 Port for SOCKS5, the HTTP Port for HTTP. The host, username and password are the same for both.

Set it up in Undetectable

One proxy entry per line. Add it while creating the profile, or in the settings of a profile you already have; the steps are the same.

  1. Start a profile

    Click New Profile, enter a Profile Name and pick local or cloud. On the configuration tab, choose a configuration close to your own OS and Chrome, and set the languages to the line's country.

  2. Open the General tab and add a New Proxy

    In the General tab, open the proxy dropdown and select New Proxy. Proxies you saved earlier in the Proxy Manager appear in the same list.

  3. Choose the protocol and paste the line

    Pick SOCKS5 or HTTP in the protocol list. In the field next to it, paste host, port, login and password, for example CONNECTION_IP:SOCKS5_PORT:USERNAME:PASSWORD. The port must match the protocol.

  4. Paste the Reset Link into IP Change Link

    This is the field Undetectable documents for mobile proxies. With it filled, the Change IP button asks the line for a new address.

  5. Check the proxy

    Press the check button. A working line shows a country flag and turns the Google, Facebook and Yandex icons green. Undetectable notes that the city it shows can differ from the provider's, because IP databases disagree.

  6. Name it and save

    Give the proxy the Coronium line's name and save. Then Save the profile, or press Open to save and launch it in one go.

Change IP, by hand or before each launch

With the Reset Link in IP Change Link, the Change IP button rotates the line from inside Undetectable. Press it while no account session is open in that profile, then reload a checker to see the new address.

Undetectable's bot can rotate for you: its settings have a Use link for IP change checkbox, and with it on the IP changes before each profile launch. Space the launches out. A Coronium line refuses a second rotation inside the minimum interval, so a bot that opens the same profile twice within a minute gets the old address the second time.

Nothing else in the profile changes. Host, port and login stay the same through every rotation, so there is no proxy entry to update unless the line itself is replaced.

Moving many profiles

For more than a handful of profiles, use the Proxy Manager under mass management: add every line once, then assign them. Undetectable recommends the manager over per-profile setup for bulk work.

The built-in proxy checker runs from three places: the profile card in the main window, the profile settings and the Proxy Manager. Checking from the card is the quickest way to spot one dead line in a long list.

Check it worked

Open these in the profile itself after it launches. Run them again after every Change IP, so you see the address the sites will see.

The IP and the carrier
Open What Is My IP through the line. The country should be the line's country and the network should be the mobile carrier, not a hosting company.
WebRTC
Run the WebRTC leak test. The only public address it should report is the line's. Your own address showing up means the browser is leaking around the proxy.
Timezone against the IP
The IP and timezone check compares the clock the browser reports with the timezone of the IP. A mismatch is one of the first things anti-fraud systems look at.

When it does not connect

The check shows no flag and grey icons
Protocol and port do not match, or the login is incomplete.
Pick SOCKS5 with the SOCKS5 Port, or HTTP with the HTTP Port, and paste the full string from List view.
Change IP does nothing
The IP Change Link is empty or truncated, or the last rotation was less than 60 seconds ago.
Paste the Reset Link again in full, wait 60 seconds and press Change IP once.
The city in the check is not where the carrier is
IP location databases disagree about mobile ranges; Undetectable notes this itself.
Judge by country and carrier. Mobile traffic leaves the carrier's network at a few gateways, so a database often places the address at a gateway city rather than where the device is.
The bot launches profiles with the old IP
Launches less than a rotation interval apart on the same line.
Space launches out, or give each bot profile its own line.
A profile works, then stops after a few weeks
The line expired, or it was replaced and now has new credentials.
Renew the line in the dashboard, or copy the new endpoint into the proxy entry.

Questions

Does Undetectable support SOCKS5 mobile proxies?

Yes. Undetectable supports HTTP and SOCKS5. A Coronium line has both ports on one host with the same login; choose the protocol and use its port.

What do I put in the IP Change Link field?

The Reset Link from the Coronium proxy card (or Rotate API link in List view). One request to it rotates the line, with at least 60 seconds between rotations. Keep it private: anyone with the link can rotate your line.

Can Undetectable rotate the IP automatically?

Its bot can: with Use link for IP change ticked, the IP changes before each profile launch. You can also put a timer on the Coronium line itself, from 60 seconds upward.

Why does the city differ from what I expected?

IP databases place mobile carrier addresses inconsistently, and Undetectable warns that the city in its check can differ from the provider's. Country and carrier are the reliable parts for a mobile line.

How should I test this before buying for every profile?

Buy one line on the 24-hour plan, set it up in one profile and work through the checks and one Change IP. If it behaves, renew it and add lines for the other profiles.

How we checked

Every Undetectable menu name and field on this page was read from the pages below on 30 October 2026. The Coronium side comes from the dashboard and the live API. There are no screenshots: we quote the names instead of showing an account we do not run. If a label in Undetectable has moved since, the tool's own page is the one to trust.
