Well shit....that's ridiculous you need that much information.
Why can't they just confirm that my email address was the one it was registered with...
That's not a lot of information. It takes less than a minute to verify your identity, and this would be the best way for security purposes. Unless someone buys/takes your private key, you're solid on verification.
Emails are more likely to be breached than private keys. A
lot more likely.
