Built for people with more than one Claude account
Logins stay fresh
Claude Code rotates its refresh tokens. ccs saves the latest tokens before every switch, so saved accounts keep working.
One-file install
Double-click ccs.exe and press Enter. No administrator rights, no developer tools, nothing else to download.
Safe by design
Only the account record changes; every other Claude Code setting is kept. Files are written atomically, and the original login is backed up on first use.
Stays on your computer
ccs talks to no server of its own. It copies local files and runs the official claude auth commands.
English and Tiếng Việt
ccs follows your system language. Switch at any time with ccs lang en or ccs lang vi.

Frequently asked questions
Windows says "Windows protected your PC". Is that normal?
Yes. Windows shows it for any program that is not code-signed. Click More info, then Run anyway. You can verify the file against the published SHA-256 checksums.
Do I need to restart Claude Code after switching?
Start a new Claude Code session, or run Developer: Reload Window in VS Code. Sessions that are already running keep the previous account until then.
Where are my accounts stored?
In the .claude-switch folder in your user profile, protected the same way as Claude Code's own login file.
Does it work on macOS?
Not yet. macOS keeps Claude Code tokens in the Keychain, which ccs does not support.
How do I uninstall it?
Run ccs uninstall. Your saved accounts stay until you delete the .claude-switch folder.
