Apple tightens security so company can't pry into password-protected iPhones, iPads

Apple has tightened its technological security so not even the company can pry into a password-protected iPhone or iPad in a move meant to reassure the millions of people who are increasingly storing vital pieces of their lives on the devices.

The additional safeguard is part of Apple's latest mobile software, iOS 8, which the Cupertino, California, company released Wednesday. Apple Inc. revealed the stronger protection in a new section of its website that is prefaced with a letter from CEO Tim Cook emphasizing the company's "fundamental" commitment to privacy and security.

The company's inability to unlock password-protected smartphones and tablets could frustrate law enforcement officials who sometimes obtain court orders to vacuum personal data off the phones for potential evidence in criminal investigations.
