Unclear Where the sign-in notice comes from, and how an administrator sets it, is not clear.
What
When you sign in on another device, Claude Code shows an approval page at /device. That page can now show a section headed "Notice from" followed by the host name, with a message, when a sign-in notice is supplied. Before, the page could only show an error message.
Why
Administrators of a gateway, a server that sits between Claude Code and the model, can show people a message when they sign in.
