I'm sorry to hear that your senior dad forgot the password he set for the device. If you are referring to a hotel safe or any electronic device where a master code is needed, the best course of action would be to contact the manufacturer or supplier of the device for assistance. They may be able to provide you with a master code or guide you on how to reset the password. It's important not to attempt random codes as this could potentially lock you out permanently. Additionally, you may also try searching for the user manual or documentation that came with the device for any information on master codes or password reset procedures.
