It’s supposed to be this super duper important and secret number, but you have to bring a physical copy to work miles away from home for some stranger to copy. Many times you have to provide the number to even apply for a job and it ends up at who knows where because the application is on a third party private website. :agony-deep:
If you know where someone grew up and their birthday, you've already got like, 5 digits of that code. Its so hilarously insecure we would literally be better off letting people just pick their own number.
