Persistent re-authentication requests when running Claude Code in tmux sessions

Description

When running Claude Code inside tmux sessions, there are frequent and persistent requests to re-authenticate, even though authentication credentials are already configured and valid.

Expected Behavior

After initial authentication, Claude Code should maintain authentication across tmux sessions and not repeatedly ask for re-authentication.

Actual Behavior

Claude Code frequently prompts for re-authentication when running in tmux sessions, interrupting workflow.

Environment

• Claude Code running in tmux sessions
• Multiple concurrent tmux sessions (session-per-issue workflow)
• Shared authentication configured at /etc/claude/.credentials.json
• Linux server environment with multiple tmux sessions

Context

We run a multi-user development environment where:

• All Claude Code sessions run as the same user
• Authentication credentials are stored in a central location
• Each tmux session corresponds to a different issue/feature branch
• Developer may have concurrent sessions

Impact

This significantly disrupts developer workflow, as authentication interruptions happen frequently and require manual intervention.

Additional Information

• Credentials file has correct permissions (660)
• ACLs are configured to allow access
• All sessions run as the same user
