Creates a one-year login that can only run Claude, the same kind claude setup-token makes. Devices use it instead of the hub's own login, so the hub's renewals no longer interrupt them.

1. Open the sign-in link in a browser where you're signed in to the account you want to add (a private window or another Chrome profile works well).
   Open Claude sign-in Copy link
   Sign-in link
2. Approve access. Claude shows you an authorization code; paste it here.

Run this in Terminal on the Mac you want to add. It installs a small background agent that keeps the Mac signed in to whichever Claude account has the most room. Needs Node.js 18 or later.

The code works once and expires . Any Claude login already on the Mac is imported automatically. Don't run it with sudo.
