But that's still using three unique digits. 1123 uses only three digits, but that doesn't make it a three-digit number, it's still a four-digit number.

- tobtoh 15y agoYou're right Corin - the title is a little misleading with hindsight. However, I was trying to reflect the angle that made the page interesting (ie that it's counter-intuitive that using less unique digits is more secure) whilst still trying to fit it within character limits.
- corin_ 15y agoIf you are still able to edit the title (can't remember when HN stops letting you do that), a more suitible one might be something along the lines of "iPhone 4-digit passcodes more secure when containing only 3 unique digits".
- tobtoh 15y agoDone - thanks for the suggestion Corin!
