What a Chrome profile is, and what it is not

A Chrome profile is a separate set of browser data on the same computer: its own bookmarks, history, saved passwords, extensions, settings and, most importantly, its own cookies. Because cookies live inside the profile, two profiles can stay signed in to two different accounts on the same site at the same time. That is the whole reason profiles exist. What a profile does not do is lock anything away from other people at the same Mac, keep your downloads apart, or stop one Google account from leaking its defaults into another inside the same profile. This guide covers how profiles work, the exact menu steps to add, switch and remove one, and where the boundary of a profile actually sits.

What Google says a profile is for

Google's own help page for the feature is short and direct about the purpose:

With profiles, you can keep all your Chrome info separate, like bookmarks, history, passwords, and other settings. Source: Google Chrome Help, Manage Chrome with multiple profiles

The same page lists two use cases: sharing a computer with several people, and keeping different accounts, such as work and personal, apart. Those are different problems, and a profile handles them with different levels of success. Keeping a work account and a personal account apart is the job a profile does well. Keeping one person's browsing private from another person at the same machine is the job it does poorly, for reasons covered further down.

In practical terms, everything Chrome stores on behalf of a website or on your behalf is scoped to the profile:

• Cookies and site storage, which is what keeps a login alive between visits.
• Saved passwords, addresses and payment methods used by autofill.
• History, and the address bar suggestions built from it.
• Bookmarks and the bookmarks bar.
• Installed extensions and their permissions.
• Site permissions such as camera, microphone and notifications.
• Startup pages, the default search engine and the theme.

A profile can exist with no Google account signed in at all. It still keeps its own cookies and bookmarks, it just does not sync anywhere. Signing a Google account into a profile adds sync on top, and Google notes that once you sign in, the profile name automatically becomes the account name. To see which folder on disk belongs to the profile you are using, open chrome://version and read the Profile Path line.

Adding, switching, renaming and removing a profile

The steps below follow the wording in Chrome's help pages as checked on October 18, 2026. The profile button is the round picture or initial at the top right of the Chrome window.

Add a profile

1. Open Chrome and select Profile at the top right.
2. Choose Add Chrome profile.
3. Decide whether to sign in with a Google account or continue without one.
4. Pick a name, a photo and a color scheme. The color is worth choosing carefully, because it is the fastest visual cue for which window belongs to which profile.

Switch between profiles

Select Profile at the top right and choose the profile you want. Each profile opens in its own window. Windows from different profiles can sit side by side, and each keeps its own logins.

If you want Chrome to ask which profile to use every time it opens, go to Profile, then Manage Chrome profiles under "Other Chrome profiles", and check Show on startup at the bottom of that screen.

Rename or recolor a profile

Open Manage Chrome profiles, select More at the top right of the profile card, then Edit. Changes save automatically. For the profile you are currently in, Profile then Customize profile does the same thing.

Delete a profile

Open Manage Chrome profiles, select the profile, then More and Delete, and confirm. Google's help page is explicit that deleting a profile erases its bookmarks, history, passwords and other settings from the computer. If the profile was signed in with sync turned on, a copy of synced data stays in the Google account. If it was never signed in, nothing survives, so export bookmarks and passwords first.

Profile, Google account, Guest window and Incognito compared

These four get mixed up constantly, partly because they all appear in the same profile menu. The table puts them on one line each.

Thing	What it separates	What survives closing it	Typical use
Chrome profile	Cookies, passwords, history, bookmarks, extensions, settings	Everything, until the profile is deleted	Work and personal kept apart on one Mac
Google account inside a profile	Gmail, Drive and other Google data on Google's side	Sign-in stays until signed out	Reaching two Gmail inboxes from one window
Guest mode	A blank, temporary profile with no access to other profiles	Nothing: history, cookies and site data are deleted on exit	Lending the computer to someone
Incognito window	A temporary cookie jar on top of the current profile	Bookmarks saved and files downloaded stay	One private session on your own computer

Two details on that table come straight from Google's help pages and are often missed. First, Guest mode cannot see or change any other profile's information, and leaving it deletes the browsing activity. Google recommends Incognito, not Guest, for private browsing on your own computer. Second, Incognito keeps cookies and site data only for the length of the session, but bookmarks you add and files you download remain afterwards. Incognito is therefore a poor tool for a second account you use every day, because you sign in again every single time.

Where the edge of a profile actually is

A profile separates what the browser stores. It does not separate what sits outside the browser, and three gaps catch people out.

There is no password on a profile. Google says so directly on the profiles page: anyone who has your device can switch to any other Chrome profile on it, and once inside can see information such as the sites you visited. A profile is a way to organize, not a way to lock. If two people share one Mac and need privacy from each other, separate macOS user accounts are the right tool, because each macOS user gets a separate Chrome install state entirely.

Downloads land in one folder. Unless you change the download location per profile in Settings, a file pulled from the work profile and a file pulled from the personal profile end up side by side in the same Downloads folder, with nothing in the file name to say where it came from.

The network and the machine are shared. Every profile leaves the Mac through the same connection and the same public address, with the same screen size, fonts and operating system version. Sites that look at those signals see one device, whichever profile you are in.

None of this makes profiles weak. It just means a profile answers the question "which account is signed in here" and not the question "who can see this".

The default account problem inside one profile

Many people skip profiles altogether and add a second Google account through the account picker in Gmail. Google supports this and documents it in Sign in to multiple accounts at once. It works, with one catch the help page spells out.

When several accounts are signed in at the same time, Google cannot always tell which one you mean, for example when a new browser window opens. In that case it may apply settings from the default account, such as Web and App Activity and ads personalization. Google also notes that the default account is usually the one you signed in with first. In daily use this shows up as Calendar invites opening in the wrong account, a Drive link asking for access you already have in the other account, or Meet joining as the personal address.

A separate profile per account removes that ambiguity, because each profile has only one Google account in it, and that account is the default by definition. That is the strongest everyday argument for profiles over the in-page account switcher.

If you move to one account per profile, clean up the old setup at the same time. In the profile that will stay personal, open the account picker in Gmail and use Sign out of all accounts, then sign back in with only the personal address. Google's help page also describes Remove an account on the same screen, which takes the extra address off the sign-in list so it stops being offered. Then name each profile after the account or client rather than after a person, because the name is what appears in the profile menu and on the profile button at the top right of every window. Small as it sounds, this one change is what stops a client email going out from the wrong address.

How Safari and Firefox handle the same job

Chrome is not the only browser on a Mac with this idea, and the differences matter if you are deciding where to put a second account.

Safari has profiles too. Apple's guide, Create distinct browsing profiles in Safari on Mac, walks through Safari > Settings > Profiles, then Start Using Profiles, and a separate window per profile via File > New Window. One difference stands out: if you store passwords in iCloud Keychain, Apple notes that those passwords are available in every profile you create. History and cookies are separated, saved passwords are not.

Firefox takes a different route. Its Multi-Account Containers extension, published by Mozilla, separates cookies by container at the level of the tab rather than the window. A work container tab and a personal container tab can sit next to each other in one window, each signed in to a different account, with color coding to tell them apart.

So the unit of separation differs: a window per profile in Chrome and Safari, a tab per container in Firefox.

When profiles stop scaling

Profiles fit a person with two or three identities. They start to strain for someone with several clients, each with its own Gmail, Slack and project tool, because every identity becomes a full browser window with its own tab strip. Finding the right inbox turns into finding the right window first, and macOS window switching does not show profile colors.

The next step some people take is a browser that keeps each web app in its own window space, with a separate cookie container per app rather than per profile. In that model, a work Gmail and a personal Gmail are two entries in one sidebar, both signed in, and a link from Slack opens inside the session it belongs to. The details differ between tools. As one example, the workspaces page of one such multi-account browser for macOS describes a container per app, and its pricing page lists a free plan of 1 workspace with up to 3 apps, with multiple accounts for one service in the paid tier at $60 a year or a one-time $129, checked on October 18, 2026. The point is not the specific product, it is that the separation moves from the window to the app.

What to change first

If you have only one Chrome profile and more than one Google account signed into it, make a second profile for the second account and give it a different color. If you already run four or more profiles and spend the day hunting for the right window, look at a per-app container setup such as SpaceDeck before adding a fifth.
