Bypassing passwords on Programmable Logic Controllers (PLCs) or Human-Machine Interfaces (HMIs) without proper authorization is illegal in most jurisdictions and violates professional ethics. It can void warranties, cause safety hazards, damage equipment, or lead to industrial espionage. Passwords are present to protect proprietary code, machine safety protocols, and operational integrity.
