Complete Multilogin Setup Tutorial 2026: Step-by-Step Guide

If you're managing multiple accounts across platforms, you've probably run into the dreaded account suspension problem. One wrong move with your browser fingerprint, and boom—everything's linked and flagged. That's where Multilogin comes in. It's an anti-detect browser that lets you run multiple accounts without them being connected. Think of it as giving each account its own digital identity.

This guide walks you through the entire setup process, from installation to advanced automation. No fluff, just what you need to get started.

System Requirements & Installation

Before downloading anything, make sure your machine can handle it. Multilogin isn't particularly heavy, but you'll want decent specs if you're running multiple profiles simultaneously.

Minimum requirements:

• OS: Windows 10+, macOS 10.14+, or Linux (Ubuntu 18.04+/Debian 10+)

• RAM: 4GB (8GB recommended for multiple profiles)

• Storage: 2GB free space

• Processor: Dual-core 2GHz or better

• Internet: Stable broadband connection

Installing on macOS:

Download the .dmg file from the official website, open it, and drag the app to your Applications folder. When you launch it for the first time, macOS might ask you to approve it in Security & Privacy settings—that's normal.

Installing on Linux:

For Ubuntu or Debian systems, grab the .deb package and install it with sudo dpkg -i multilogin-latest.deb, followed by sudo apt-get install -f to handle any dependencies. Fedora and RHEL users can do the same with the .rpm package using sudo rpm -i multilogin-latest.rpm.

When managing multiple browser profiles with different fingerprints, you'll quickly realize that IP address management is just as important as browser configuration. 👉 Check out reliable residential proxy solutions that work seamlessly with anti-detect browsers to ensure each profile maintains its own unique digital footprint without triggering platform security systems.

Creating Your First Browser Profile

Once you're logged in, you'll land on the dashboard. Click "Create Profile" and you'll see two browser options: Mimic (Chromium-based) and Stealthfox (Firefox-based). For most use cases, Mimic works great and has better compatibility with automation tools.

Fingerprint configuration:

This is where the magic happens. Multilogin generates a unique fingerprint for each profile, but you need to configure it properly:

• Canvas Fingerprinting: Enable with noise mode—this adds subtle variations to prevent tracking

• WebGL Fingerprinting: Same deal, noise mode keeps you under the radar

• Audio Context: Keep it enabled

• Fonts: Use real fonts for the most authentic fingerprint

• Timezone & Geolocation: Set to auto if you're using proxies; they'll match your proxy location automatically

• Language: Stick with en-US unless you have specific needs

• Screen Resolution: 1920x1080 is common and won't raise flags

Name your profile something you'll remember (like "Amazon-Seller-01" or "FB-Client-Nike"), add tags if you're organizing multiple accounts, and save it.

Proxy Setup: Don't Skip This

Here's the thing: Multilogin masks your browser fingerprint beautifully, but it doesn't hide your IP address. If you're running five "different" accounts from the same IP, platforms will notice. You need proxies.

Adding a proxy to your profile:

When editing or creating a profile, scroll to the proxy section. You'll need these details from your proxy provider:

• Host address

• Port number

• Username and password (if authentication is required)

• Proxy type (HTTP, HTTPS, or SOCKS5)

For example, an HTTP proxy might look like this: Host is "proxy.example.com", port is 8080, then enter your credentials. SOCKS5 proxies work similarly but typically use port 1080.

After entering the details, hit "Check Proxy" to verify everything works. The test should confirm your IP location matches the proxy, show a high anonymity level, and have a connection speed under 3 seconds.

Which proxies should you use?

Residential proxies are your best bet for most account management scenarios. They come from real residential ISPs, so they look completely legitimate to platforms. Mobile proxies work great too, especially for social media accounts. Datacenter proxies are cheaper but get flagged more easily—avoid them unless you're just scraping public data.

For serious multi-account operations where detection means losing revenue, 👉 explore residential proxy networks with genuine IP addresses from real devices rather than risking datacenter IPs that platforms can easily identify and block.

Testing Your Profile

Before you start using a profile for real work, test it. Open the profile and visit these fingerprint testing sites:

• Pixelscan.net: Comprehensive fingerprint analysis

• BrowserLeaks.com: Checks for IP leaks and fingerprint consistency

• IPLeak.net: Simple IP and DNS leak test

What you're looking for:

Your IP address should match your proxy location. All fingerprint parameters (canvas, WebGL, fonts, etc.) should appear unique and consistent. There shouldn't be any WebRTC leaks exposing your real IP. The timezone should align with your proxy's geographic location.

If something looks off, go back to your profile settings and adjust. Better to catch issues now than after you've been using an account for weeks.

Team Collaboration Features

If you're working with a team, Multilogin has built-in sharing features. Go to Settings → Team Management and invite members by email. You can assign different permission levels:

• Admin: Full access to everything

• Editor: Can create and modify profiles

• Viewer: Can only view profiles, not change them

To share specific profiles, right-click on them and select "Share," then choose which team members get access. You can also organize profiles into folders and share entire folders with your team.

Permission tips:

Only give admin access to people who absolutely need it. Use editor permissions for people managing day-to-day operations. Set up viewers for stakeholders who need visibility but shouldn't be touching configurations.

Automation with Selenium and API

If you're running repetitive tasks across multiple accounts, automation saves massive amounts of time. Multilogin works with Selenium WebDriver and has its own API.

Basic API endpoints:

To start a profile programmatically, send a GET request to http://localhost:35000/api/v1/profile/start?profileId={id}. To stop it, use the stop endpoint with the same profile ID. You can also fetch profile information with the profile info endpoint.

The API returns a WebDriver port that you can connect to with Selenium, Puppeteer, or Playwright. This lets you automate anything you'd normally do manually in a browser—filling forms, clicking buttons, scraping data, whatever you need.

Organization and Best Practices

As your profile count grows, organization becomes critical. Create a logical folder structure: one folder for Amazon accounts, another for Facebook clients, maybe a testing folder for experimental profiles.

Naming conventions matter:

Use a consistent format like Platform-Purpose-Number. For example: "Amazon-Seller-01", "FB-Client-Nike", "Instagram-Growth-03". This makes it easy to find what you need at a glance.

Use the notes field in each profile to store important details: login credentials, account purpose, which proxy provider you're using, and the last activity date. Future you will thank present you for this documentation.

Performance optimization:

Close profiles when you're not using them—they consume RAM even in the background. Regularly clear profile caches to prevent bloat. If you're running many profiles simultaneously, limit the number active at once. Disable extensions you don't need in each profile.

Troubleshooting Common Problems

Profile won't start? Check if another profile is already using the same port. Restart the Multilogin application. Clear the profile cache from Settings → Advanced. Make sure your antivirus isn't blocking ports, and verify you have enough RAM available.

Proxy connection failed? Use the "Check Proxy" button to diagnose the issue. Double-check your username and password. Contact your proxy provider to make sure the IP hasn't been banned. Try switching to a different proxy server. Check your firewall settings.

Accounts still getting banned? This is usually about behavior, not just technical setup. Are you using residential proxies instead of datacenter ones? Does your proxy location make sense for the account's history? Are you logging in at realistic times of day? Is your automation mimicking human behavior or running at robot speed? Did you warm up the account gradually or jump straight into heavy activity?

Moving Forward

You now have everything you need to run Multilogin effectively. Start with a few profiles, test them thoroughly, and gradually scale up as you get comfortable with the workflow.

The key to success isn't just technical setup—it's understanding how platforms detect suspicious behavior and staying one step ahead. Keep your profiles organized, use quality proxies, and always test before committing real accounts to a new setup.

If you run into issues not covered here, Multilogin's documentation and support team are solid resources. The community forums also have experienced users who've solved most problems you'll encounter.

Now go set up those profiles and reclaim control over your multi-account operations.
