thank you. I just assumed it was configurable, like Android,, but, with the downvotes, I thought I was wrong.
Of course it would take much less time for a 4-digit numeric code -- but AFAIK at this point the length of the password is unknown, so, the ACLU claiming fraud based on the assumption of the length of the password is not correct.
When you tap the home button on an iPhone, it shows you empty circles indicating how many characters are in the passcode. It also varies the entry keypad depending upon whether it's alphanumeric or numeric.
In other words, if you are holding the phone in your hand, you can figure out how many digits the passcode is, and whether it's alphanumeric or just numeric, without entering a single character.
