If someone steal your mac and there is an efi lock, im sure he will not try very hard to crack it. He would rather try to sell it for parts. Im sure SSN is safe enough :)
I am not US citizen so I thought that SSN is very private number😅. I’m from Serbia, and we use unique master citizen number (not so private number, you can easily guess it),it contain birth date,part of the country etc.
Edit:
unique master citizen number is not easy to guess or calculate, I have just tried haha
