6 Digits Are Better Than 4! iOS 9 to Boost Passcode Security | The Mac Security Blog

And although there were plenty of new features announced for the upcoming upgrade to OS X — dubbed El Capitan — perhaps the security news which will impact the most iPhone and iPad users is that Apple will be beefing up security on iDevices running iOS 9, by requiring users to upgrade from a 4-digit passcode to one containing 6 digits.

Two extra digits. Can that really add a whole lot more security?

Well, actually yes.

You see, a six digit passcode has one million possible combinations instead of 10,000.

Graham Cluley, writing on the Mac Security Blog, explains why a six-digit passcode is good, but an alphanumeric passcode is even better.

This is only available on a device with a Touch ID. Presumably, not having a Touch ID means you’ll be typing your PIN a lot more often, so they didn’t include the feature for older devices.

    You have been able to use complex passwords since at least ios6. You’re not restricted to 4 numbers.

    • Of course, but in iOS 9, Apple will require a minimum of 6 digits. At least that’s what they say on their website (as I point out, it’s not yet implemented in the beta).

  3. I thought that if you already have a PIN that IOS9 won’t force a change. What changes is that the default length of PIN going forward will be 6, and you will have to change a setting to be able to use a 4 digit pin. The assumption being that most people will just set the 6-digit pin and not go looking for a setting to allow a shorter one.

    My assumption was that if you are upgrading and already have the shorter PIN then that setting would be turned on as part of the upgrade OR that the existing pin would be grandparented in, and any new PIN would default to 6. I don’t have the IOS beta yet to try either supposition out.

    • I installed the beta, and it asked me to set a 4-digit PIN. My guess is that it’ll be turned on in a later beta.
