How to set up a proxy in Multilogin (Multilogin X & Multilogin 6)
Updated:
Multilogin (both Multilogin X and Multilogin 6 with Mimic and Stealthfox browser cores) parses standard ip:port:user:pass strings automatically when pasted into the Custom Proxy settings. Pairing each Multilogin profile with a dedicated Static ISP or private IPv4 proxy from VinaProxy delivers enterprise-grade isolation for Amazon, eBay, Etsy, and Google Ads accounts.

Multilogin for teams that run accounts at scale
Multilogin is one of the longest-established antidetect browsers and is often chosen by agencies and larger operations: affiliate teams, e-commerce companies and social media managers who need shared workspaces, member roles and profiles that many people can open.
With many hands on the same profiles, the risk is inconsistency. Someone launches a profile from a different office, or a new member swaps the proxy for a test and forgets to put it back. Treat the proxy as a fixed property of each profile, decided once and changed only on purpose.
Recommended Multilogin Custom Proxy settings
Inside Proxy Settings -> Custom, use the parameters below for VinaProxy proxies:
| Multilogin Setting | Recommended Value | Purpose |
|---|---|---|
| Proxy Type | HTTP | Matches VinaProxy's authenticated HTTP(S) proxy servers |
| IP / Host : Port : Login : Password | Paste ip:port:user:pass | Auto-splits all four fields when pasted into the Host box |
| Timezone & Geolocation | Automatic (Based on IP) | Populates timezone and coordinates from the proxy's location |
| WebRTC | Altered | Prevents local LAN IP leaks in Mimic and Stealthfox |
Best practices for Mimic and Stealthfox profiles
- Use Mimic (Chromium core) for Google Ads, Facebook Ads, Amazon Seller Central, and TikTok Shop
- Use Stealthfox (Firefox core) when diversifying browser engine footprints across eBay or Etsy stores
- Always click Check proxy before launching a new profile so Multilogin pre-fetches accurate geolocation metadata
- Never run two separate profiles simultaneously on the same static IPv4 address
Mimic, Stealthfox and the proxy
Multilogin offers a Chromium-based core (Mimic) and a Firefox-based core (Stealthfox). The proxy setup is identical for both, and the same VinaProxy line works with either. Choose the core based on what the target site expects, not on the proxy.
What does depend on the proxy is the rest of the fingerprint. Let timezone, geolocation and language be derived from the proxy IP, and set WebRTC to a mode that shows the proxy address rather than your local one. A profile on a Singapore proxy with a Hanoi timezone is an easy inconsistency to avoid.
Proxy hygiene in a shared workspace
- Agree on one owner for proxy changes; other members only launch profiles.
- Use folders or tags by client and country so a US profile never ends up with a Hong Kong IP by accident.
- If you launch profiles through automation scripts, the proxy saved in the profile normally applies there as well, so there is no need to pass it separately.
- Track expiry dates and renew only the proxies whose profiles are still in use.
Multilogin proxy errors and what they mean
- Authentication failed or 407: wrong username or password. Copy the pair from Orders again rather than retyping.
- Proxy test hangs or reports no connection: wrong host or port, a type other than HTTP, or an expired order.
- Profile launches but sites show the wrong country: verify the line on the proxy checker; if it is wrong there as well, raise a ticket.
- Works for you but not for a teammate: they may be opening a copy of the profile without the proxy. Check that everyone uses the same profile.
Step by step
- 1
Open Create New Profile in Multilogin
Launch Multilogin X (with the local agent running) or Multilogin 6 and click Create new profile.
- 2
Select Custom Proxy -> HTTP
Under Proxy settings, select Custom and choose HTTP as the protocol.
- 3
Paste ip:port:user:pass and click Check Proxy
Paste your VinaProxy proxy string into the IP/Host field and click Check proxy to confirm the exit IP and country.
- 4
Create and launch the profile
Save the profile and click Start to open Mimic or Stealthfox.
Frequently asked questions
Why does Multilogin report 'Could not connect to proxy'?
Confirm that the proxy protocol is set to HTTP (not SOCKS5) and that no whitespace was copied with the password. You can verify the credentials anytime in our free proxy checker.
Does Multilogin X route proxy traffic through its web dashboard or my machine?
Your local Multilogin X Agent connects directly from your machine to the VinaProxy proxy server, ensuring low latency and zero third-party relay bottlenecks.
Which VinaProxy proxy plan is recommended for Multilogin?
Most Multilogin users choose US Static ISP, Vietnam Static ISP, or UK Dedicated IPv4 for high-value merchant profiles.
Do I need Multilogin's own proxies, or can I bring my own?
You can bring your own. Choose the custom proxy option and enter your VinaProxy HTTP proxy; it gives the profile a dedicated static IP.
Does the same proxy work in Mimic and Stealthfox profiles?
Yes, the setup is the same for both cores. Just avoid giving one IP to two profiles that should look like different people.
How should a large team split proxies across Multilogin profiles?
One IP per profile, grouped by client and country. Bigger orders lower the price per IP, see pricing, and the reseller program suits agencies that resell access.
Will the IP change if a teammate opens the profile from another country?
No. The profile connects through the saved proxy wherever it is opened, so the site sees the same static IP.
