@brian_armstrong Cool! Could you also improve the security of your iOS app? In fact, imagine you are on the way, only have your iPhone with you and you recently change your phone number and forgot to change it in your Coinbase account. @brian_armstrong Imagine someone takes your old number and tries to hack your Facebook account. You will be alerted by a reset password kind of email. Freaking out you will remember that you didn’t change the phone number in your @coinbase account! 😱
