My main concern is that there isn't a reliable way to know your information is securely stored[0].
> A few years ago, I received a letter in the mail addressed to my then-toddler. It was from a company I had never heard of. Apparently, there had been a breach and some customer information had been stolen. They offered a year of credit monitoring and other services. I had to read through every single word in that barrage of text to find out that this was a subcontractor with the hospital where my kids were born. So my kid's information was stolen before he could talk. Interestingly, they didn't send any letter about his twin brother. I'm pretty sure his name was right there next to his brother's in the database.
> Here was a company that I had no interaction with, that I had never done business with, that somehow managed to lose our private information to criminals. That's the problem with online identity. If I upload my ID online for verification, it has to go through the wires. Once it reaches someone else's server, I can never get it back, and I have no control over what they do with it.
All those parties are copying and transferring your information, and it's only a matter of time before it leaks.
