Strict isolation
Assign a unique sticky IP to each profile using a distinct -session- tag. Two profiles on one IP defeats the isolation Multilogin works to provide.
Multilogin X pairs its Mimic and Stealthfox browsers with a hardened fingerprint engine, but the exit IP is still yours to provide. This guide covers exactly where Multilogin keeps its proxy fields, how to use proxy templates, and how to bind a ProxyOmega residential IP to each profile.
Multilogin is one of the original antidetect browsers and is widely treated as the enterprise-grade option. The current generation, Multilogin X, ships two browser cores, Mimic (Chromium-based) and Stealthfox (Firefox-based), and gives each profile a fully managed fingerprint covering canvas, WebGL, fonts, audio, timezone, WebRTC and more.
It is built for teams that run large numbers of accounts with strict isolation, agencies, ad buyers, data operations and marketplaces, and includes granular team roles, cloud profile storage and an automation API for Selenium and Playwright. Multilogin manages identities; the IP address behind each profile comes from a proxy you configure.
Multilogin's fingerprinting is thorough, but it cannot change your IP address by itself. If multiple Mimic or Stealthfox profiles all exit through one IP, the accounts inside them can be correlated regardless of how distinct each fingerprint is. The IP has to come from a proxy, and for account work it should be residential.
Residential IPs come from real consumer connections, so they avoid the blanket suspicion applied to datacenter ranges. The reliable pattern is one clean residential IP per Multilogin profile, held stable for the life of a session.
Assign a unique sticky IP to each profile using a distinct -session- tag. Two profiles on one IP defeats the isolation Multilogin works to provide.
Multilogin's proxy check reads IP-dependent data so the fingerprint stays consistent with the exit IP. Choose the country in the username and the browser aligns timezone and geolocation.
Multilogin's proxy template manager lets you save a ProxyOmega configuration once and apply it across many profiles, so scaling to hundreds of profiles takes seconds rather than manual re-entry.
In Multilogin X the proxy lives in the Proxy section of each profile, and you set the connection type to Custom. Multilogin runs an automatic proxy check as you enter details, so you get instant feedback. For scale, save the configuration as a proxy template.
Targeting is carried on the username with dash-separated parameters, and the password is your ProxyOmega account API key.
residential.proxyomega.com and port 10000 (any assigned port in 10000-10199). Multilogin also accepts a pasted IP:port:login:password string.youruser-country-fr-session-mx12-ttl-1440.Every ProxyOmega plan works identically inside Multilogin X, so pick by the job. High-volume account management fits Budget Unlimited, while accounts that demand precise targeting or a fixed identity justify a premium tier.
| Workload | Plan | Why |
|---|---|---|
| Large-scale profile management | Budget Unlimited | Flat port-based pricing with per-profile sticky IPs via unique -session- ids. |
| Precise targeting (country, state, city, ASN) | Platinum | Pay-per-GB Tier-1 residential with the deepest geo and ASN control on port 20228. |
| Mobile or carrier-sensitive accounts | Mobile | Real 4G/5G IPs with country and session on port 20229. |
| A permanent fixed US identity | Static ISP | Dedicated Dallas IP on isp.proxyomega.com that never rotates. |
| Speed-critical in-browser work | Premium Unlimited | Dedicated 200Mbps-1Gbps tier on premium.proxyomega.com:8000. |
A failed Multilogin proxy check is almost always the API key, an unsupported username parameter, or a whitelist conflict. Check these in order.
Confirm the password is your ProxyOmega API key, not your dashboard login password. Then confirm every dash-parameter on the username is supported by the plan; an invalid parameter rejects the entire username and returns 407.
This points to IP whitelisting. Once any IP is whitelisted, only whitelisted IPs connect and username/password auth is bypassed. Whitelist the machine running Multilogin or remove the whitelist.
Correct the two-letter -country- code and let Multilogin re-run its proxy check so it re-reads IP-dependent data and realigns the fingerprint.
Use the same host and port as HTTP and switch the protocol to SOCKS5. ProxyOmega does not use a separate SOCKS5 port.
