An agency, a social media manager or a freelancer who runs accounts for several clients often logs in to all of them from the same office, the same browser and the same connection. To a platform, that pattern looks like a network of linked accounts: repeated security checks, forced logouts, accounts wrongly tied to one another.

Proxies let you give each account its own stable, separate network environment. This guide explains how to set things up properly, and where acceptable use ends.

Social networks fight fake accounts, spam and account takeovers. To do so, they connect accounts that share technical or behavioral signals:

  • The IP address: several accounts behind the same address, or an account that switches countries from one hour to the next.
  • The device and browser: operating system, screen resolution, fonts, time zone, language. Taken together, these details form a fairly distinctive fingerprint.
  • Cookies and local storage: a single browser that opens several accounts one after another leaves traces that tie them together.
  • Behavior: simultaneous logins, identical actions at the same times, the same content shared everywhere.
  • Account details: phone number, recovery email, ad payment method.

Being linked is not a violation in itself. But mixing the signals of several clients creates confusion: unusual login alerts, verification requests, and the risk that an incident on one account spills over onto the others. The goal is not to hide the fact that you manage these accounts, but to give each one a stable, separate environment.

One fixed, dedicated IP per account, for the long run

The simplest rule to follow: each account always logs in from the same IP, and that IP is used by that account alone.

  • Fixed, because a real user usually logs in from the same places. An IP that changes with every session triggers alerts.
  • Dedicated, because a shared IP makes you inherit the behavior of strangers. Our article on dedicated vs shared proxies covers this risk in detail.
  • For the long run, because stability builds up over months. Renew the same proxy instead of ordering a new one: you keep the same address. Auto-renewal, available as an option and never switched on by default, makes sure a missed renewal does not let an account's IP expire.

ISP proxies are a good fit for this: the address belongs to a consumer ISP, just like an office or home connection, while being hosted on fast, stable professional infrastructure. To learn more, read what an ISP proxy is; the France, Spain and Europe offers are on the offers page.

If one IP per account is the goal, the non-negotiable minimum is one IP per client: never route the accounts of two different clients through the same address.

Multi-profile browser: one profile, one IP, one consistent country

A multi-profile browser isolates each account in its own profile, with its own cookies, storage, fingerprint and proxy. It is the basic tool for managing several accounts without mixing them up.

  • One proxy per profile, never shared between profiles that belong to different clients. Enter it in host:port:username:password format, over HTTP or SOCKS5; our guide on how to set up a proxy shows you where.
  • A consistent country: the profile's IP, time zone and language all match the country where the account lives. A French brand managed from a Spanish IP, in a browser set to English, sends mixed signals. Our guide on how to choose a proxy location helps you decide.
  • No IP change mid-session: no rotating IP on a logged-in account, no VPN on top of the proxy. If a proxy goes down, do not switch "temporarily" to another address: put work on that account on hold.
  • A check before the first login: open our What is my IP tool inside the profile and confirm that the address, country and ISP it shows are the proxy's. Also make sure WebRTC is not leaking your real IP.

If several team members work on the same account, they all go through the same profile, and therefore the same IP. On the other hand, it is perfectly normal for the client to log in from their phone too: the point is not to hide those logins, but to stop your own access from changing all the time.

In short: one fixed, dedicated IP per account, one browser profile per account, the same country everywhere and no IP change mid-session. Proxies bring stability to legitimate account management; they never manufacture an audience.

Dedicated ISP or mobile IP: which should you choose?

For day-to-day management from a computer (publishing, scheduling, messages, analytics), one dedicated ISP proxy per account is the default choice. A mobile IP makes sense when an account is mostly used the way it would be from a phone, on a mobile-first platform, or when a sensitive account needs to show the most ordinary address possible: mobile addresses are shared by many subscribers, and platforms are used to seeing them change.

Airproxy's 4G mobile IP is a French line reserved for a single customer, rented by the month, with unlimited data. A line only shows one address at a time: dedicate it to one account, or to the accounts of a single client, and only change the IP between two sessions. Our guide to 4G mobile proxies, rotating vs sticky IP explains when to change it.

Organizing your proxies when you manage several clients

With a handful of accounts, memory is enough. With several clients, you need a method:

  • Name every proxy: in the Airproxy customer dashboard, an alias per proxy (the client and the account, for example) prevents mix-ups when you set up a profile or renew.
  • Keep a register that maps each account to its browser profile and its proxy, and export your credentials instead of copying them by hand.
  • Keep track of expiry dates: a rental lasts 30 days; renew in one click, or turn on auto-renewal for the accounts you manage over the long term.
  • Secure access: two-factor authentication on every account, a password manager with per-client permissions, and access revoked as soon as a team member leaves.
  • Never reassign an IP from one client to another: when a client leaves, let their proxies expire and get new ones for the next client.
  • Keep your invoices, generated automatically for every transaction, so you can easily rebill your clients.

Staying within platform rules

Managing your clients' accounts, at their request, is a recognized line of work. Platforms often provide business tools that give an agency delegated access without sharing passwords: where they exist, use them first.

Proxies must never be used to:

  • create fake accounts or accounts in bulk;
  • artificially inflate engagement (followers, likes, comments, views) with accounts you control;
  • astroturf, in other words fake spontaneous public support;
  • send unsolicited messages in bulk;
  • get around a suspension or restriction imposed by a platform.

Read each platform's terms, especially the parts on automation and third-party tools. On the data side, your clients' messages, comments and follower lists contain personal data: the GDPR applies, and your role (often that of a processor) must be set out in your contract. This reminder is not legal advice.

Frequently asked questions

Does every account really need its own IP?

It is the safest rule and the easiest one to document. The bare minimum is never to mix accounts belonging to different clients on the same address.

Is a VPN enough to manage several accounts?

No. A consumer VPN hands out addresses shared by many users, often classified as hosting addresses, and they change from one connection to the next. That is the exact opposite of the fixed, dedicated IP an account needs.

Can I use the same proxy for several accounts of the same client?

That is acceptable for accounts that genuinely belong to the same client and are already linked, such as a page and its ad account. For sensitive accounts, one IP per account is still the better option.

What should I do if an account's proxy stops responding?

Do not log in to the account from another address in the meantime. Test the proxy with our proxy checker, then open a ticket from your customer dashboard if the problem persists.

Do platforms ban proxies?

Their rules mainly target behavior: fake accounts, unauthorized automation, getting around restrictions. Terms vary from one platform to another, so read the terms of every network you manage.
