Apple’s security nightmare continues with new figures showing how easy it’s become to crack the password blocking access to an iPhone.

GrayKey, the device manufactured by Grayshift and which is currently being purchased by police departments in the United States en-masse, can hack an iPhone no matter how long and complex the password, though it goes without saying that the more characters being used, the more it takes for the process to complete.

And according to Matthew Green, assistant professor and cryptographer at John Hopkins Information Security Institute, it’s possible to bypass a 4-digit passcode on the iPhone in a little over 6 minutes, while in the worst case scenario, it could take up to 13 minutes.

Needless to say, the cracking times increase as the passcodes become more complex, and for a 10-digit code, GrayKey could need some 4629 day…
