Setup guide
Multilogin X proxy setup: Custom HTTP
Multilogin X runs profiles in its own browser cores, Mimic on Chromium and Stealthfox on Firefox, each with a separate fingerprint. It sells proxies of its own, and the Proxy section of every profile also accepts a third-party proxy under Custom. The labels follow the Multilogin X help centre.
Before you start
- A Multilogin X account, with the desktop agent connected so that profiles can launch.
- Your HOST, PORT, USERNAME and PASSWORD from the service page.
- One IP set aside for every profile that will hold a login.
Your connection details
Sign in to the dashboard and open the service you bought. Its page shows the host, port, username and password for that service. There is no single ProxyPanda address to remember, so copy them from there each time. The code in these guides uses the placeholders below; replace each one with your own value.
- HOST
- The proxy address for this service, exactly as the service page shows it.
- PORT
- The port to connect to. Copy it with the host, since it can differ from one service to the next.
- USERNAME
- Your proxy login. It is separate from the email you use for the dashboard.
- PASSWORD
- Copy it in full. On residential, the options you choose in the dashboard are added to the end of the password, so a password typed from memory loses them.
You can skip the username and password by adding the IP address you connect from to the service’s allowlist. Then only HOST and PORT go into your code.
The examples use HTTP, which reaches https sites through an encrypted tunnel. SOCKS5 works too: residential ports accept both, and ISP and datacenter proxies switch protocol in the dashboard.
Steps
Go to Profiles, then Browser, then Create
The General section comes first: profile name, folder, tags, operating system and browser. Mimic is the Chromium-based core that Multilogin recommends; its help lists Stealthfox as legacy. Choose the operating system of the kind of device the account should appear to use.
Open the Proxy section and choose Custom
Proxy offers four choices: Multilogin, Custom, Template and None. Custom is the one for a proxy you bought elsewhere. Of the protocols it lists, HTTP, HTTPS and SOCKS5, pick HTTP or SOCKS5 to match your service page. Sites on https load through either.
Paste the whole line into IP or host
Multilogin takes IP:port:login:password in the host field and spreads the parts into port, login and password for you. The residential page in the dashboard can export lines in that exact order; for ISP and datacenter, join each listed IP’s host, port, username and password with colons.
Profiles › Browser › Create › Proxy › Custom Protocol: HTTP IP or host: HOST:PORT:USERNAME:PASSWORDWait for the check to finish
Multilogin tests the proxy as soon as the details are in. Proxy check passed means it connected and collected the IP data it needs; Proxy check failed means it did not, so correct the details before saving. For a profile that already exists, select it in the list and press Check proxy in the top menu.
Review the Masked fingerprint settings
In the Fingerprint section, Timezone, Geolocation data and WebRTC all default to Masked, which lines each up with the proxy: the clock follows its location, coordinates land near it, and WebRTC reports its address. Browser languages works differently. Masked sends English by default, so switch it to Custom and choose the proxy country’s language when the account expects one.
Launch the profile and open api.ipify.org
Save, start the profile from the list, and visit https://api.ipify.org in its first tab. That IP is what sites log for the profile. For a second opinion on location, Multilogin’s help suggests checkers such as MaxMind.
Rotating and sticky IPs
Each Multilogin profile should keep one address for as long as the account exists. An ISP IP does that for the rental term and sits on a home broadband network, which is what a months-old account ought to look like. One IP per profile.
Proxy templates save a proxy for reuse, which is handy for datacenter tools and a trap for accounts: one template applied to five profiles makes five accounts share an address. Keep templates for work that has no login.
Quick profiles accept a list of proxies used Sequentially or Randomly. That fits throwaway browsing and testing. It does not fit an account that must return from the same place every time.
On residential, switch to Sticky IP in the dashboard and copy the password only after that, because the session choice lives in it. Multilogin also handles allowlisted proxies with Login and Password left blank, and the dashboard does offer an allowlist, but a username and password works from wherever you connect.
Common errors and fixes
“Proxy check failed”
Multilogin could not connect with those details. Confirm the protocol matches your service page and that the pasted line has four parts and nothing trailing. Multilogin’s help adds a quick test: a proxy that fails in plain Chrome or Firefox will fail here too, which tells a wrong detail apart from a local problem.
“Wrong proxy data” as a profile starts
Multilogin shows this when a proxy has stopped answering or has no traffic left. On residential, check your balance first, since that line is billed by the gigabyte. Then confirm the line still reads ip:port:username:password and run Check proxy again.
ERR_CONNECTION_CLOSED, ERR_CONNECTION_RESET or ERR_TIMED_OUT on a page
Multilogin’s advice is to test the proxy before anything else. If Check proxy passes and pages still break, look for local interference: its help names VPNs, antivirus software and firewalls, and suggests another network to rule out your provider.
Profiles struggle to start although the check passes
Multilogin’s troubleshooting lists the computer’s clock among the causes. Turn on automatic time and time zone sync in your operating system, restart the app, reconnect the agent and try the profile again.
Which line to pick
An ISP IP for each long-lived Multilogin profile is the closest match to one person at home. Residential with Sticky IP handles short jobs where a new address next time does no harm. Datacenter keeps costs low for dashboards and tools that accept server addresses.
Using Multilogin to keep several accounts apart is fine. Using it for fraud, spam or replaying leaked passwords is not, and ends the account. Where we draw the line
