I think #2FA with these little 6 digit codes from a dongle or a little app is a good hack to somehow fix our huge security and identity issues on the internet. But there are two implementations that make my blood boil every. single. time.:
#Paypal not accepting ENTER as confirmation of the entered 6 digit code (you need the mouse, arrrrgh!)
#Github just autoloading after the 6th digit is entered, because no-one ever mistyped anything.
@cweickhmann Yep, and inevitably, the ones with auto-submit use letters too, increasing the chances of mistyping.
