> I feel like SSN is a big liability with little benefit
Your feelings on the matter are quite irrelevant -- they want every bit of data about your financial life as possible. Including your mortgage, income, etc. The SSN it the ultimate primary key. You can't even get a new one if your identity is stolen. The more often they can link that to an email address, phone number, etc, the stronger the signal they get from sources that only have those bits.
