What issue are you seeing?

Running rsync from Codex CLI to our Hetzner box hangs forever whenever the remote host falls back to password auth. The CLI never surfaces the root@78.47.165.136's password: prompt, so the transfer
just sits there until I abort it manually. Example command (PII redacted):

rsync -av --exclude node_modules --exclude dist infra/orchestrator/app/ root@78.47.165.136:/opt/kora-repo/infra/orchestrator/app/

There’s no stdout/stderr beyond the initial connection setup—just a stuck process because the password prompt isn’t shown.

What steps can reproduce the bug?

1. Open a Codex CLI session (danger-full-access sandbox, zsh).
2. Run the rsync command above to a host that requests a password even though a key path is passed.
3. Observe that the session never moves forward; you have to CTRL-C to recover.

No session ID/token metrics surfaced; the command never finishes.

What is the expected behavior?

The CLI should either show the SSH password prompt so the user can respond or provide pw, or get to type pass in the cli-ui, or fail fast with an explicit error (“password prompt detected; interactive input not supported”) instead of hanging indefinitely.
