If the request is reasonable, and doesn't interfere with your tasks and responsibilities, help the coworker. If it does interfere with your tasks, ask a supervisor what to do.
Pretend that I did not hear the request.
It is legal for a coworker to ask for you password. You are not required to oblige that request. Also, it might be against company policy for you to oblige that request.
Hiring that coworker
To help my coworker get a promotion, I used the art of aggrandizement.
A request for help could be a plea, or an entreaty.
Infer that you have exhausted your personal knowledge and refer them to a supervisor.
A person that is already in your chosen profession can help you with your career. A coworker or your boss may also be able to help you advance in your career.
