How to Run Two Claude Accounts at the Same Time (2026)

If you have more than one Claude account — say a work account and a personal one, or one per client — you've hit the wall: the Claude desktop app only lets you be logged into one at a time. Switch accounts and you're logging out, logging back in, losing your place. Do that ten times a day and it's maddening.

Here's how to run two (or more) Claude accounts at the same time, each in its own window, each staying logged in.

Why the Claude app only allows one account

The Claude desktop app stores its login in a single profile on your computer. One profile = one signed-in account. There's no built-in "switch account" button like Gmail has, so the only native option is the full log-out / log-in dance.

The fix: one window per account

The clean solution is to give each account its own separate profile and window. When each account runs in its own isolated space, they don't conflict — you can have your work Claude and your personal Claude open side by side, both logged in, both remembering their own chats.

That's exactly what Claude Accounts does. It's a tiny $14 launcher that:

1. Lets you add each account by name ("Work", "Personal", "Client A").
2. Opens each one in its own isolated, persistent window.
3. Keeps every account logged in — you sign in once and it sticks.

No logging out. No account-sharing. No limit-bypassing. Each account you already own simply gets its own window.

Is this against Anthropic's terms of service?

No. Running your own multiple accounts in separate windows doesn't create accounts, share logins, or change any usage limits. It uses the same kind of separate-profile launch that browsers use for multiple Google profiles. You're just organizing the accounts you already pay for. (What Anthropic's terms prohibit is sharing one login between people, or evading usage limits — neither of which this does.)

Step by step

1. Get Claude Accounts ($14 one-time, Mac & Windows).
2. Open it and click "+ Add account".
3. Name it (e.g. "Work") and log into that Claude account once.
4. Repeat for each account.
5. Click any account to open its window. Open as many as you want — they run at the same time, side by side.

That's it. Two Claude accounts, both live, no more logging in and out.
