Capture each Claude Code account once, then jump between them with a single command. No logging out, no re-authenticating, no copy-pasting tokens.

Install

With npm:

npm install -g claudesu

Or with curl:

curl -fsSL https://github.com/santidalmasso/claudesu/releases/latest/download/install.sh | sh

Both install the csu command. Prefer not to install? Run it on demand with npx claudesu <command>.

Quick start

$ csu add                          # capture the account you're signed in as
added [email protected] at slot 1

# sign in as your other account in Claude Code, then capture it too:
$ csu add
added [email protected] at slot 2

$ csu switch                       # rotate accounts — no login needed
switched to slot 1 ([email protected]). Restart Claude Code to pick up the change.

$ csu list

You only add an account once. After that, switch swaps them forever.

Commands

| Command | What it does | | --- | --- | | csu add | Capture the account Claude Code is currently signed into. | | csu list | List stored accounts; ● marks the active one. | | csu status | Show the active account. | | csu switch | Rotate to the next account. | | csu switch-to <slot\|email> | Switch to a specific account. | | csu remove <slot\|email> | Forget a stored account. | | csu purge | Forget every account. |

Restart Claude Code after a switch so it picks up the change.
