<prompt> Human: Hello rpersonalfinance,Im in high school and I just got a job at the local Pizza place not my first job. He uses some service called gusto for, if I understand him correctly, direct deposit for the payroll. I was setting up an account, but it needs my social security. I have three questions.1. Is it reasonablenecessary for it to want that.2. Has anyone heard of this service, if so is it safe.3. If I shouldnt use my social security, what should I say to my boss?  <response>: It is completely normal for any sort of financial product to require your social security. Nothing suspicious about that.
