🔐 Security

• BCrypt password hashing (12 rounds) - industry standard
• Constant-time hash comparison (no timing attacks)
• Console password censoring - passwords never leak to logs
• Tab-completion blocked on password commands
• IP change alerts + max accounts per IP
• Kick on too many attempts - never temp-ban (prevents account lockout trolling)
