Agencies, sellers and marketers often need to run several accounts on the same platform: one per client, per brand or per market. The hard part is not logging in. It is keeping the accounts from being connected, so a problem with one does not spread to the others, and so each account looks as normal as it is.
This guide explains what links accounts and compares the ways to keep them apart.
What links accounts together
Platforms connect accounts through anything they share. The main signals:
| Signal | Example |
|---|---|
| Cookies and storage | A tracking ID set while you were logged into account A, read back in account B |
| Browser fingerprint | The same canvas hash, GPU, fonts and screen in every account |
| IP address | Every account logging in from the office network |
| WebRTC and DNS | Your real IP leaking from behind a proxy |
| Account details | Shared phone numbers, emails, payment cards or recovery details |
| Behaviour | The same working hours, the same navigation patterns, logging in to accounts one after another |
The browser covers the first four. The last two are up to you.
Your options, compared
| Method | Separates cookies | Separates fingerprint | Separates network | Practical at 50+ accounts |
|---|---|---|---|---|
| Log out and back in | No | No | No | No |
| Incognito windows | Partly | No | No | No |
| Chrome profiles | Yes | No | No | Awkward |
| Different browsers | Yes | Partly | No | No |
| Virtual machines | Yes | Partly | Yes, with setup | Expensive |
| Antidetect browser | Yes | Yes | Yes | Yes |
Chrome profiles are fine for a handful of personal accounts, but every profile reports the same fingerprint and IP. Virtual machines give strong separation, but each needs gigabytes of memory, an OS licence and maintenance, and VMs have their own detectable traits. An antidetect browser gives each account a separate browser profile with its own fingerprint, proxy and storage, at the cost of one browser window.
A setup that scales
- One profile per account. Never open two accounts in the same profile, even briefly.
- One proxy per account. Use a static residential or ISP proxy in the account’s country, and keep the same one for the life of the account. Changing IP country every day looks more suspicious than a stable IP.
- Match the profile to the proxy. Timezone, language and location should fit the proxy’s country. NexLogin sets these automatically from the exit IP.
- Check for leaks once. Open the profile and run the WebRTC leak test and the fingerprint test. The public IP should be the proxy’s, and the consistency checks should pass.
- Keep details separate. Use a different email, phone number and payment method per account where the platform expects separate owners.
- Organise. Name profiles clearly, group them into folders by client or platform, and note what each one is for.
- Share access properly. When someone else needs an account, share the profile instead of the password. They work from the account’s usual fingerprint and IP, and you can take access back.
Mistakes that link accounts anyway
- Logging into a second account “just once” from your normal browser.
- Reusing one proxy across several accounts.
- Using a proxy whose country does not match the account’s history.
- Installing the same unusual extension in every profile.
- Copying cookies between profiles.
Summary
Treat each account as if it lived on its own computer: its own browser, its own fingerprint, its own IP and its own details. An antidetect browser makes that practical for dozens or hundreds of accounts. NexLogin is built for this. Try it free for 7 days on Windows.
