But you can guess any whole number if you have an unlimited amount of tries. if you are interacting programmatically with a live system there is always a limit to the number of tries that you can do.

- CharlesMerriam2 7y agoiPhones and most other devices are limited. After a few tries, you will start down an increasing lock-out time for the next guesses. The back out does not apply to changing the PIN of an unlocked phone to see if that PIN gives a warning. TL;DR: You can find the blacklist this way but not unlock a phone.
- jiveturkey 7y agoTFA (and the paper) specifically address rate-limited guessing, with a complete lockout after a small maximum #tries. This is not about unlimited guessing, obviously, because 4 or even 6 digits can just be guessed in under a second!
