Claude Desktop keeps one account signed in at a time. If you bounce between a work account and a personal account, you know the routine: log out, log in, lose your place, repeat. Here are the ways to run two Claude accounts on a Mac, what each costs you, and the setup that keeps both signed in at once.
Claude Desktop stores your login in a single data directory. When you sign in to a second account, it overwrites the first. That is why there is no built-in account switcher: the app was designed around one signed-in user per machine. Everything below is about working around that single data directory, either by hand or automatically.
The obvious option. It works, but it clears your session every single switch, so you lose your current chat context and wait through a fresh login each time. Fine once a day, painful if you switch accounts ten times before lunch.
Open claude.ai in two Chrome or Safari profiles and each keeps its own session, so both stay signed in. The catch is that you are now in the browser, not the desktop app: no dedicated dock icon per account, no global shortcut, and none of the desktop-only conveniences. It is a real option if you only live on the web, but it is not multiple Claude Desktop accounts.
Create another Mac login and install Claude there. This genuinely isolates the two accounts, but you have to use fast user switching to reach the other one, and you cannot see both at the same time on the same desktop. Heavy-handed for what should be a quick toggle.
The pattern: every manual workaround is really about giving each account its own data directory. The friction is in doing that by hand. Automate that one step and the whole problem disappears.
Multi-Claude runs the real Claude Desktop app once per account, each pointed at its own data directory. The result is multiple Claude profiles that are all signed in at the same time, each a genuine Mac app with its own dock icon, Spotlight result, and chat history. You switch with Cmd-Tab, exactly like moving between Safari and Mail.
| Method | Both signed in at once | Real desktop app | Effort to switch |
|---|---|---|---|
| Log out and in | No | Yes | High, every time |
| Browser profiles | Yes | No, web only | Low |
| Second Mac user | Yes | Yes | High, user switching |
| Multi-Claude | Yes | Yes | Low, Cmd-Tab |
Download the app, drag it to Applications, and open it. On first run it detects your existing Claude install and offers to import that history into a named profile, keeping the original as a backup.
Add one profile for each Claude account, for example Work and Personal. Give each a name and a color so you can tell them apart at a glance.
Each profile launches as its own Mac app with its own data directory, so signing in to one never logs out the others.
Open every account at once and switch between them with Cmd-Tab. Nothing to quit, nothing to reload.
Yes. Claude Desktop only keeps one account signed in at a time, but you can run multiple Claude accounts side by side by giving each account its own app and data directory. Multi-Claude does this for you, so work and personal can both be open and signed in at once.
Logging out and back in is the manual way, and it is slow because it clears your session every time. Instead, give each account a separate data directory so its login is stored independently. Multi-Claude creates one Mac app per profile, each with its own directory, so no account ever logs the others out.
You can use claude.ai in separate Chrome or Safari profiles, and that keeps two web sessions signed in. It does not give you the desktop app, its dock icon, global shortcuts, or local file access. Multi-Claude runs the real Claude Desktop app per account instead of the browser.
Anthropic's Consumer Terms permit running multiple legitimate accounts, such as a work account and a personal account, on one machine. Multi-Claude is built for people with real separate accounts, not for stacking free accounts.
As many as you want. Each account is a separate profile and a separate Mac app. Most people settle on two or three, such as work, personal, and a side project.
