What’s going on with security at PayPal?
This confuses me about discussions like these on HN:On the one hand, there are so many stories on HN complaining about incompetent and dystopian security practices in the financial industry.And many tips on how to cope with it. Like not giving PayPal your bank account, rather pay 3% to put a credit card between PayPal and your bank account. And to keep your phone number secret to avoid sim swapping and PayPal exposing it.It seems to be a fight between customers who are supposed to try and hide as much data as possible from the companies. Because that data causes a threat to you. And the companies that try to get as much data as possible.On the other hand, cryptographic solutions which put the user in control and do not expose any data to the outside world are frowned upon. To me, it seems the logical solution. I want a private key, that only I know. And to be able to sign transactions with it without exposing any data.If such a solution based on cryptography would be widely used, I would hold a smallish amount of buying power on my "crypto wallet" and use that for day to day transactions. And regularly refill it directly from my bank account.The best of both worlds: For my smallish day-to-day transactions, I am in full control of the security and privacy. And my savings stay on my bank, completely shielded from my day-to-day transactions.Why does everyone on HN hate this approach?
