Claude Code v2.1.305 ·

Sign-in falls back to pasting a code when the local listener cannot start

If Claude Code cannot open its local sign-in listener, login now shows a URL and asks you to paste the code instead of failing

Unclear Which login flows, if any, ask for the extra scope is not known.

What

When you sign in, Claude Code normally starts a small local listener that receives the result from your browser. If that listener could not start, login failed.

  • Now login continues with a manual URL and asks you to paste the code shown after signing in, at the prompt "Paste code here > ".
  • The login screen says "Use the URL below to sign in" instead of "Browser didn't open? Use the url below to sign in".
  • claude auth login in a terminal prints "Sign in at:" with the URL and waits for the code; Ctrl-D closes the prompt and stops the login.
  • Running out of file handles (EMFILE or ENFILE) still stops login with an error.
  • If the fallback cannot be used, you see "Couldn't start the local listener that receives the browser sign-in. Try again." with " Run with --debug for the underlying error." added.
  • Separately, the sign-in URL builder can add one extra permission scope through a new alsoRequestScope option; no caller was found using it.

Why

Login can work on headless or remote machines and where the local port is blocked, and failures point you to --debug.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Confirmed since Anthropic's documentation has since written up --debug, on using. | `--debug` | Print full HTTP request and response to stderr | cli-sdks-libraries/cli/using see the edit
