Why would an insurance company need information on someone who is not listed on a home loan?

So my boyfriend recently bought his first home and I agreed to move in with him. However, his home insurance agent is asking for him to provide her with all of my information (social security number, driver’s license number)

What questions should be asked to the insurance agent while taking a policy/plan?

Hello friends an health insurance agent is going to come my home this weekend.As a newbie to insurance, what questions shall i ask him while accepting for a policy detailedly? What are the precautions I should take before accepting a policy for me/my family? Shall i search any information about insurance?
