This totally reminds me of SSN use, when initially they were just a number (not secret) to identify a person, and then suddenly people started to use them as a key for authorisation, because someone had a bright idea how to implement things fast/simple/cheap (cheap part comes at expense of others)
- lpribis 8mo agoRather than being about fast/simple/cheap, I think using SSN as a key was more about the fact that SSN is the only common identifier that almost all US citizens have.
- breakingcups 8mo agoYes, designing and implementing a new common identifier almost all US citizens have would have been less cheap and fast.
- Dylan16807 8mo agoI think you're using the word "key" differently than OP. You're talking about identifiers, and they're talking about security. SSNs were a good potential identifier, until the people that needed security cheaped out and started using SSNs as a bad implementation of security. Now they're bad at both purposes!
- bob1029 8mo agoTax ids were never meant to be used as a form of global identification. If you go look in a real bank core, you'll find this field does not have any uniqueness constraints.
