The command copies all logins, or a selection such as claude, codex, or grok. Both machines need the command. Destination credentials stay unless --replace is set. David Heinemeier Hansson said the stream holds login files and account metadata, stays in memory and on stdin, and does not put tokens in command arguments. Local settings and history stay on each machine. Hansson said the tests used fixture credentials and a simulated SSH connection.

Pull request 15430 synchronizes account names and command IDs with the source, including accounts already present. When the destination has no receiver, the copy can supply a temporary one over SSH. David Heinemeier Hansson said a real transfer to an older Omarchy machine synchronized all three Claude names and IDs without replacing existing credentials. David Heinemeier Hansson opened and merged both pull requests.
