Switch to a six-digit mobile passcode

Even though Apple has made six-digit passcodes the default for iPhone users, many still prefer the four-digit option (or worse, none at all), since it makes getting into your device faster.

That length might seem good enough, but it’s guessable by specialized GrayKey devices. To stay on the safe side, use a 9- to 12-digit password […]
