Sign in before you upload or submit an app:
The CLI prints the Niblet consent URL and tries to open it in your browser. Review the account and permissions, approve the request, then return to the terminal when the browser confirms the connection. If no window opens, use the printed URL. Keep the CLI running during sign-in. The authorization link expires after five minutes and must return to the same computer through a temporary 127.0.0.1 callback.

Sign in without opening a browser

Use this when you want to open the link manually on the same computer. It is not a remote-device login: opening the link on another computer sends the callback to that computer instead of the waiting CLI.

Sign out

The CLI revokes its refresh token when possible and always clears the local session. If remote revocation fails, it tells you after removing the local credential.
Do not copy access or refresh tokens into shell history, source files, MCP configuration, chat messages, or bug reports.
