Add an external proxy to a Multilogin profile
This walkthrough shows where Multilogin X keeps the proxy field and how to fill it in. On the proxy step of a Mimic or Stealthfox profile, point External proxy at a sticky StealthProxy lane, run the built-in check, and align the timezone — three steps, no extension or scripts.
Adding the external proxy in Multilogin X
Multilogin treats the proxy as part of the profile definition. Set it on the proxy step when you create the profile and it sticks with that identity.
1 · Choose External proxy on the proxy step
Create or edit a Mimic (Chromium) or Stealthfox (Firefox) profile. On the proxy step, switch from the built-in/none option to External proxy so Multilogin routes through your StealthProxy lane rather than its own network.
2 · Set SOCKS5 and paste credentials
Pick connection SOCKS5 (HTTP works too), then enter the host, port, username and password shown for this proxy in your dashboard. Each proxy is one dedicated Polish mobile modem, so this profile keeps one Polish exit and ASN (e.g. AS12912) until you rotate it.
3 · Run the proxy check, then align geo
Use Multilogin's proxy check to confirm a Polish city and mobile ASN before launch. Set the profile timezone to Europe/Warsaw and language to pl-PL so the fingerprint Multilogin generates agrees with the IP geo.
Built for isolated Multilogin profiles
One exit per profile
Each Mimic/Stealthfox profile maps to its own sticky Polish lane — the isolation Multilogin builds stays intact at the network layer.
External proxy ready
Paste SOCKS5 or HTTP straight into the External proxy step; the built-in proxy check confirms the Polish exit.
ASN-stable
Lanes hold a consistent Polish mobile ASN and carrier across sessions, so long-lived profiles look like returning devices.
Survives reboots
The proxy is stored with the profile and the session is sticky, so it reconnects to the same exit after restarts.
