cc-switch: Multiple Claude Code Accounts

Switch between Claude Code subscriptions (e.g. Team + Max) via macOS Keychain.

Setup

1. Login and backup each account

Login with your first account:

claude /login

Backup the credentials (check the subscription type first):

security find-generic-password -s "Claude Code-credentials" -a "$(whoami)" -w | \
  python3 -c "import sys,json; print(json.load(sys.stdin).get('claudeAiOauth',{}).get('subscriptionType','?'))"

Save it under a backup name:

CREDS=$(security find-generic-password -s "Claude Code-credentials" -a "$(whoami)" -w)
security add-generic-password -s "Claude Code-credentials-backup-team" -a "$(whoami)" \
  -l "Claude Code-credentials-backup-team" -w "$CREDS"

Delete the active entry and repeat for your second account:

security delete-generic-password -s "Claude Code-credentials" -a "$(whoami)" >/dev/null 2>&1
claude /login
# ... then backup as "Claude Code-credentials-backup-max" (same steps, different name)

2. Install cc-switch

Put the cc-switch script in your PATH (e.g. ~/bin/cc-switch), make it executable. Update the TEAM_SVC and MAX_SVC variables to match your backup names.

3. Add aliases

alias teamcc='cc-switch team'
alias maxcc='cc-switch max'
alias ccwhich='cc-switch which'

Usage

teamcc           # launch with Team plan
maxcc           # launch with Max plan
maxcc -r myses  # launch with Max plan, resume session "myses"
ccwhich         # show active plan

How it works

Claude Code stores OAuth credentials in macOS Keychain under Claude Code-credentials. The script swaps the active entry with a backup before launching. Each running session caches credentials in memory, so swapping doesn't affect already-running sessions.

Important: Unset CLAUDE_CODE_OAUTH_TOKEN if set — it takes precedence over the keychain.
