A multi account browser for a Mac, and how isolation really works

Search for a multi account browser and most of the first page is anti-detect software: tools that give every browser profile its own fake device fingerprint and its own proxy. That is one answer to the question, and it is the right one for a narrow group of people. Most Mac users asking it have a simpler need. They own two or three Google accounts, a couple of Slack workspaces, maybe a client's Microsoft 365 login, and they want all of them signed in at the same time without logging out and back in. Those are two different jobs, and they need different levels of isolation. This guide separates them, explains what each kind of tool actually keeps apart, and lists what the built-in options on a Mac already do. Prices and limits below were checked on the vendors' own pages on October 18, 2026.

Two jobs that share one search term

The phrase "multi account browser" covers two situations that look similar from the outside.

The first is holding several of your own accounts open at once. A freelancer with a personal Gmail and two client Gmails. An agency employee who manages social accounts for several brands under their own login. A developer with a work GitHub and a personal one. The sites involved know these accounts belong to one person, and that is fine. The only problem is that a normal browser window can hold one session per site.

The second is making accounts look like they come from unrelated people. This is what anti-detect browsers are built for. They change the browser fingerprint that sites read, such as screen size, fonts, graphics details and time zone, and they route each profile through a different proxy so the IP address differs as well. Ad buyers, affiliate marketers and scraping teams are the stated audience on most of those product pages.

The first job only needs separate storage for cookies and site data. The second needs separate storage plus a disguised device and network. Buying a tool for the second job to solve the first adds cost and complexity without changing the result that matters, which is staying signed in.

What "isolation" means in a browser

A site recognises a returning user through several layers, and each kind of multi account tool covers a different subset of them.

• Cookies and site storage. Cookies, local storage, IndexedDB and similar stores hold the session. If two tabs share this layer, they share the login. Separating it is enough to run two accounts of the same service side by side.
• Cache and service workers. Usually separated together with cookies. They rarely matter for logins, but they affect whether a site's offline data mixes between accounts.
• IP address. Every tab on the same Mac and network leaves from the same address unless a proxy or VPN is used for some of them.
• Fingerprint. The combination of hardware, fonts, screen, language and graphics details that a script can read. Two profiles on the same Mac produce the same fingerprint unless a tool alters it.

Built-in profiles, containers and per-app sessions all work on the first two layers. Anti-detect browsers work on all four. That is the whole difference, and it explains why the prices are so far apart.

The options already on a Mac

Before installing anything, check what the browsers on the machine already do. All of the following separate cookies and site data.

Chrome profiles

Google's help page on managing Chrome with multiple profiles describes profiles as a way to keep bookmarks, history, passwords and other settings separate, and names work and personal accounts as a typical case. A profile is added from the Profile button at the top right with Add Chrome profile. Each profile opens its own windows. Two cautions from the same page: anyone using the Mac can switch to any profile on it, and removing a profile erases its bookmarks, history and passwords from the computer.

Safari profiles

Safari on current versions of macOS has profiles. The Safari profiles guide gives the path: Safari > Settings, then Profiles, then Start Using Profiles the first time. A new window for a profile is opened from File > New Window. One detail is easy to miss. Passwords stored in iCloud Keychain are available in every profile, so the profile separates sessions but not saved passwords.

Safari can also turn a single site into its own app with File > Add to Dock. Apple's page on Safari web apps says a web app shares no browsing history, cookies, website data or settings with Safari. That makes it a quick way to keep one extra account of one service in its own window.

Firefox containers

The Firefox Multi-Account Containers extension, published by Firefox, separates website storage into colour-coded container tabs. Its listing states that cookies downloaded by one container are not available to other containers, and gives signing in to work email and home email in two different container tabs as the main example. Unlike profiles, containers live in the same window, so two accounts of the same site can sit in neighbouring tabs.

Anti-detect browsers, and what the price buys

Anti-detect tools such as GoLogin, Multilogin, AdsPower and Octo Browser are built around profiles that each carry a generated fingerprint and an assigned proxy. On a Mac they install as a separate browser application with its own profile manager.

Prices are usually set by the number of profiles. On the GoLogin pricing page on October 18, 2026, the free plan allowed up to 3 profiles, and the smallest paid plan, Professional 10, allowed up to 10 profiles for $9 per month, or $4.50 per month when billed annually. Higher tiers raise the profile count and add residential proxy data, team sharing and automation.

What the money buys is the fingerprint and network layer. For someone who only needs to keep a few owned accounts signed in, that layer does not change anything visible. It also changes the risk picture. Many platforms set rules on how many accounts one person may hold and how those accounts may be operated, and these rules differ by service. Anyone considering a fingerprint tool for social or ad accounts should read the terms of the specific platform first, since a disguised device does not change what those terms allow.

Comparing the four approaches

Approach	Separates logins	Same window	Separate IP or fingerprint	Cost
Chrome or Safari profiles	Yes	No	No	Free, built in
Safari web app per site	Yes, for that site	No, its own app	No	Free, built in
Firefox Multi-Account Containers	Yes	Yes, per tab	No, unless a VPN is added	Free extension
Per-app sessions in an app aggregation browser	Yes	Yes, per app	No	Free tier, then paid
Anti-detect browser	Yes	Yes	Yes	Free tier, then priced per profile

The table shows where the real decision lies. If the accounts belong to the user and the goal is convenience, the first four rows all solve it, and the choice comes down to how the windows should be arranged. If the goal is for sites not to link the accounts, only the last row addresses it.

Where each one stops working day to day

Isolation is only half of the experience. The other half is how much effort it takes to live with it.

Profiles are reliable but heavy. Each profile is a full browser window with its own toolbar, extensions and tab strip. With three profiles, the Dock still shows one browser icon, and finding the right window means using the profile menu or cycling through windows. Notifications from all profiles arrive under the same application name.

Containers are lighter, but they live inside one browser, and a link opened from an email can land in the default container rather than the intended one unless containers are assigned to specific sites. The extension's own settings handle that assignment, but each new site needs it set once.

Safari web apps are tidy for one or two services. Each needs to be created and named by hand, and each is a separate app in the Applications folder of the home folder.

Anti-detect browsers add a separate application with its own vendor account, and a monthly bill that scales with the number of profiles.

An app aggregation browser for owned accounts

There is one more approach aimed squarely at the first job. An app aggregation browser keeps each web app, such as Gmail, Slack or Notion, as an entry in a sidebar, and gives each entry its own cookie container. Because the separation is per app rather than per window, two accounts of the same service can be added as two entries and switched with a click.

On one macOS example of this kind, the steps follow the same pattern: right-click an app already in the sidebar, choose Add as Another Account (separate session), and a second entry such as "Gmail 2" opens the sign-in page. Apps can be grouped into workspaces such as a day job and a side project, each with its own set of apps and sign-ins. Its pricing page lists a free plan of one workspace with up to three apps, and a Pro plan from $5 per month billed yearly, or $129 one-time, with the multiple-accounts feature in Pro and in the 14-day trial. A single license covers up to three Macs. It does not alter fingerprints or IP addresses, so it belongs with the first four rows of the table, not the last.

Setups for three common cases

The right arrangement depends less on the tool than on how many accounts there are and how long they stay open. Three patterns cover most Mac users.

One personal account and one work account

This is the case built-in profiles were designed for. Create a second profile in Chrome or Safari, sign the work account into it, and keep the personal account in the default profile. Give each profile a different colour so the window itself shows which account is in front. In Chrome, turning on Show on startup in the profile manager asks which profile to open every time the browser launches, which prevents work tabs from opening in the personal window by accident.

Several client accounts of the same service

A freelancer with four client Google Workspace logins needs four sessions of the same site. Four profiles work, but they mean four sets of windows and toolbars. Containers or per-app sessions are lighter here, because the accounts sit next to each other and switching is a tab or a sidebar click rather than a window hunt. Name each container or app after the client rather than the email address, so that the label still makes sense when a client changes their domain.

Accounts that must not be linked

If the requirement is that a platform should not see the accounts as connected, none of the built-in options meet it, because all of them share one IP address and one fingerprint. That is the only case where an anti-detect browser addresses the actual requirement, and it is also the case where checking the platform's terms matters most before starting.

What to change first

List the accounts that need to stay signed in, and mark which ones only need separate logins and which, if any, genuinely need separate devices on the network. For separate logins, start with Safari or Chrome profiles, or try SpaceDeck if the accounts are web apps that stay open all day.
