SSNs are generally considered public information but how the SSN is linked to other information is usually the more difficult bit to find and it’s generally pay-walled. (Any jackass with a business license and a credit card can usually buy background check information for ‘hiring’.)
But no, it shouldn’t be solely used for authentication. That is just dumb. However, it can be used as part of a larger verification and validation scheme while building authentication/authorization profiles. In most systems that I have seen that use full or partial SSNs, it is always linked to several other identifiers that need to match.

I’ve been saying this for literal years now. They should release a publicly searchable database of every single SSN, name, and DOB. Force organizations to stop using those as a form of ID, because they’re not secure and never have been.
Give it like a year of lead time. Like announce “March 1 2027, we’ll post the database” and then that gives institutions a full year to figure something new out.

This is the reality in other countries. In Sweden, our “SSN” is our date of birth followed by four numbers that have different meanings depending on when you were born. During the period I was born it was an area code, and a binary of male/female and a control number. This has changed over time to not be exactly the same for newer generations. All of this information is available publicly to search for through our version of the IRS that then trickles out to various private companies that just publish it out right.
I personally have a dislike for this system, as I am a major privacy enjoyer. But people can’t really do anything with the information if they had it. If someone looks up my name and SSN, they have it, but can’t bring me harm.
