Apple moves to six-digit passcode in iOS 9
Apple plans to require six-digit passcodes to unlock its latest mobile devices that use iOS 9, its forthcoming mobile operating system.
Users already have the option in iOS 8 of setting a much longer passcode than four digits, which is the current minimum requirement. Symbols and letters can also be used.
Increasing the minimum number of digits to six means that there will be 1 million possible combinations rather than 10,000, which “will be a lot tougher to crack,” Apple wrote on its website.
The move to longer passcodes is not likely to please U.S. authorities, who have expressed fears that stronger security measures, including encryption, may make it more difficult to obtain information for time-sensitive investigations, such as terrorism.
