I mean I don’t know a ton about SQL but one thing to keep in mind about SSNs is they were not originally meant to be used for identification but because we have no form of national id and places still needed a way to verify who you are people just started using SSNs for that since it’s something everyone has and there wasn’t really a better option. So now the government has been having to try and make them work for that and make them more secure. The better solution would be to make some form of national id that is designed to be secure but Republicans and people like Musk would probably call that government overreach or a way to spy and track people.
