Set up a 4G proxy in Multilogin

Why a 4G proxy in Multilogin?

Multilogin isolates each profile: cookies, browser fingerprint, time zone. The IP address, though, comes from the proxy you attach to the profile. With a ShadowProxy 4G proxy, websites see the IP of a French mobile subscriber, just like an ordinary smartphone on 4G.

Each proxy is a physical modem with its own SIM card, reserved for a single customer. The IP stays the same until you change it, which keeps your profiles consistent from one session to the next.

This guide shows where the proxy setting is in Multilogin, which fields to fill in with your ShadowProxy details, how to check the connection and how to change IP. The general method, valid for every multi-profile browser, is in our anti-detect browser guide.

1. Get your ShadowProxy access details

In your customer area, open 4G proxies then your proxy. You will find two lines, in the format address:port:username:password:

HTTP    proxy.shadowproxy.fr:10001:username:password
SOCKS5  proxy.shadowproxy.fr:20001:username:password

The HTTP port starts with 1 (100xx), the SOCKS5 port with 2 (200xx). Both go out through the same modem and the same IP.

2. Add the proxy to the Multilogin profile

1. Open the profile settings and go to the Proxy section.
2. Choose Custom, meaning your own proxy, rather than Multilogin’s built-in proxy.
3. Select the SOCKS5 (recommended) or HTTP type.
4. Enter your access details in the format IP:port:login:password, i.e. proxy.shadowproxy.fr:20001:username:password. Our proxies use a username and password: there is no IP address to whitelist with us.

Multilogin promotes its own proxies, but every profile accepts custom HTTP, HTTPS and SOCKS5 proxies.

3. Check the connection

Run the proxy check from the Proxy section. “Proxy check passed” means Multilogin connected to the proxy and retrieved the IP-related data. Make sure the IP is French and matches the one in your customer area.

4. Match the time zone and language

A French IP with a time zone or language from another country is an inconsistency that websites notice. In the Multilogin profile, let the time zone and geolocation follow the proxy IP, or set them to Europe/Paris, and choose a language consistent with a user in France.

5. Change IP whenever you want

From your customer area, with the Change IP button, or by opening your personal rotation link (on the proxy page): a single call is enough, from a browser or a script. The new address is active in under 20 seconds. No need to edit the Multilogin profile: the host and port stay the same, only the exit IP changes.

Good practice

• One proxy per profile or per small group of related profiles (one client, one project), so unrelated accounts are not linked together.
• SOCKS5 preferably, HTTP if a tool does not support SOCKS5: both go out through the same IP.
• Do not change IP in the middle of a signed-in session: do it between two sessions.
• Respect the terms of use of the sites you use.
