The hot new feature on the latest iPhone is a fingerprint scanner that will take the place of pass codes and even passwords. But how safe is it?

Cyber security expert Keith Squires says sure, an NSA agent can hack your phone.

"It's hackable if you steal someone's fingerprint with some sort of pliable material." 

But Squires doubts the average crook will be that motivated or tech savvy enough.

"Right now only about half the people even set a pass code on their iPhone, so if it's something that works well maybe you get better security overall for the general population."

The fingerprint scanner will be available on the iPhone 5s and experts suspect every high end Android and Windows phone will now follow suit.
