What
If someone without a claude.ai subscription or login tries to use Remote Control, Claude Code now shows a specific error: "You must be logged in to use Remote Control. Remote Control is only available with claude.ai subscriptions. Run claude auth login to sign in with your claude.ai account."
Why
This gives a clear, actionable message instead of a generic failure when Remote Control is used without the required login.

Confirmed since
Anthropic's documentation has since written up claude auth login, on Continue local sessions from any device with Remote Control.
Run `claude auth login` and choose the claude.ai option. If the message names `ANTHROPIC_API_KEY` or `ANTHROPIC_AUTH_TOKEN`, remove it wherever it's set: your shell environment or the `env` block of a [settings file](/docs/en/settings-refe…remote-control see the edit
