They’re so simple, in fact, that even the less tech-savvy should have no problem setting them up with a few clicks.
The short version: There are very few instances in which you have to hand over your SSN, and those are mostly limited to requests from employers, financial institutions (for tax reporting), and government agencies (like the DMV). While some businesses may refuse to do business with you should you decline to share your SSN, you can always take your business elsewhere.
