Feature request: Multi-account / profile support

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Switching between Claude accounts currently requires claude logout followed by claude login. This becomes friction in workflows where multiple accounts are involved.

Use Cases

• Separate personal and work/organization accounts
• Testing or development with different subscription tiers
• Keeping project contexts isolated across different accounts
• Consultants or contractors managing distinct project environments

Attempted Workaround

Tried swapping macOS Keychain credentials (Claude Code-credentials) programmatically via shell scripts before launching Claude Code. The keychain updates correctly, but Claude Code doesn't pick up the changed credentials — it continues using the previously authenticated session.

Proposed Solution

Named profile support, similar to AWS CLI or GitHub CLI:

claude --profile work
claude --profile personal

# Or
claude auth switch work
claude auth list

Alternatively, environment variable support:

CLAUDE_PROFILE=work claude

Environment

• macOS
• Claude Code v2.1.19
• Installed via npm
