Problem Statement

The Claude Code welcome banner displays the authenticated user's email address (e.g., user@example.com's Organization). There is no way to suppress or hide this.

This is a privacy concern when screen-sharing, live-streaming, recording demos, pair programming, or working in public spaces. The email is visible to anyone who can see your screen whenever you open a new Claude Code session.

Proposed Solution

Add a configuration option to hide the email/org from the welcome banner. Either of these would work:

• An environment variable: CLAUDE_CODE_HIDE_EMAIL=true
• A /config setting: privacy.hideEmailInBanner: true

The banner would still show the model, effort level, and working directory — just not the account email.

Alternative Solutions

• CLAUDE_CODE_HIDE_CWD=true hides the working directory but does not affect the email display.
• Switching to API key auth (ANTHROPIC_API_KEY) removes the email from the banner, but loses Claude Pro features and requires per-token billing — not a practical workaround for Pro subscribers.
