Short answer: Claude Desktop keeps one account signed in at a time, because your login, conversations and settings all live in a single data folder. To use a second account without logging out, that account needs a data folder of its own. On Windows, there are three ways to get there:
If you use Claude for work and for yourself, or for several clients, you have hit the wall: switching accounts means logging out, logging back in, and losing your place. Here is what each option really gives you, and where each one breaks.
Claude Desktop stores everything about your session - login, history, settings - in one data folder on your PC. Signing in to another account simply replaces the first one. And Claude runs as a single instance: launching it a second time does not open a new window, it brings the existing one back.
So the problem is not really about accounts. It is about folders: one folder, one signed-in account. Every working solution gives each account its own folder.
If you are happy using Claude in the browser, create one browser profile per account. In Chrome, click your profile picture, then Add; in Edge, click the profile icon, then Add profile. Each browser profile keeps its own cookies, so each one stays signed in to its own account on claude.ai.
Claude Desktop accepts a launch option, --user-data-dir, that tells it which data folder to use. Start Claude with a different folder and you get a second, independent Claude window with its own login.
C:\ClaudeProfiles\Work.Claude.exe. Claude Desktop is installed as a Windows app package, in a hidden, protected folder whose name includes the version number, such as C:\Program Files\WindowsApps\Claude_<version>_x64__pzs8sxrjxfjjc\app\Claude.exe."C:\Program Files\WindowsApps\Claude_…\app\Claude.exe" --user-data-dir="C:\ClaudeProfiles\Work"It works on day one. These are the problems that follow, all taken from real support cases:
CLAUDE_CONFIG_DIR - which a Windows shortcut cannot do.Claude Desktop Manager is a small Windows app that does Way 2 for you, and takes care of each of those problems:
It is free to download and use: unlimited profiles, one Claude at a time, and several in parallel for 15 minutes to try it. Standard ($10, once) runs two at the same time with no time limit; Pro ($30, once) removes every limit.
🖥️ Windows app - download it from a PC. This page reads fine on a phone, but the installer only runs on Windows 10 / 11.
| Browser profiles | Manual launch flag | Claude Desktop Manager | |
|---|---|---|---|
| Claude Desktop app | No, web app | Yes | Yes |
| After a Claude update | Keeps working | Shortcut breaks | Keeps working |
| Google / SSO / passkey sign-in | Yes | Lands in the wrong window | Yes, with Add an account |
| Cowork on every account | No | Fails on extra accounts | Yes |
| Claude Code kept apart | - | Only with a script | Yes |
| Cost | Free | Free | Free · $10 or $30 once for parallel use |
In short: if the web app is enough, use browser profiles. If you want Claude Desktop with two accounts and do not mind fixing things after updates, the manual way works. If you rely on Claude Desktop every day, Claude Desktop Manager saves you the maintenance.
Yes, but not with the manual method as it is. For any account other than the one Claude uses by default, Claude Desktop downloads the Cowork virtual machine into one folder and then looks for it in another, so Cowork stops with "VHDX file not found". It breaks again whenever Claude refreshes that image.
Claude Desktop Manager keeps both locations in sync every time a profile starts. If Cowork ever refuses to start on a profile, close that profile, then choose Repair Cowork… from its options. Your Cowork session data is never touched.
Nothing here bypasses or modifies Claude. Each profile runs the official Claude Desktop app, signed in to an account you own - exactly like being signed in on two different computers. Each account keeps its own subscription and its own usage limits, so nothing is being evaded. What Anthropic's terms prohibit is sharing one account between several people, or creating accounts to get around usage limits. If in doubt about your situation, refer to Anthropic's Terms of Service.
Not out of the box. Claude Desktop keeps a single main window, and opening it again just brings that window back. To have several Claude windows side by side - each with its own account, or even the same account - each window needs its own data folder, set up by hand with a launch flag or managed for you by Claude Desktop Manager.
Not natively. Claude Desktop keeps one account signed in at a time, so switching means logging out and back in. Using several accounts at once requires a separate data folder per account.
Keep each account signed in to its own profile. With Claude Desktop Manager you then switch windows from the tray menu, with the global switcher, or with a keyboard shortcut assigned to each profile - nothing is ever logged out.
Yes. Each Claude Desktop Manager profile keeps its own Claude Code settings and session history, so work and personal projects never mix. More in Claude Desktop + Claude Code on one PC.
No. Claude Desktop Manager finds the new Claude location after every update. You don't need to do anything.
No. Claude Desktop Manager runs on Windows 10 (build 19041 or later) and Windows 11, on x64 and ARM64.
