Think you have a strong passcode? change for Alphanumeric. Alphanumeric Passcode is almost uncrackable. If you are using an iPhone passcode with 6 numbers or worse just 4 numbers, then you may want to change based on new report earlier in this week which revealed that a 6 digit passcode can be cracked in less the one hours and the 4-digit passcode in minutes using a new and relatively cheap technology called GrayKey to unlock iPhones.
What is GrayKey
GrayKey is a little box from Grayshift that cracks the passcode on iPhones. You plug an iPhone into the device, and after a few minutes or hours depending on the length of your passcode, it spits out your code. With that in hand, anyone can log in to your iPhone and access all of its contents.
If you update your passcode to Alphanumeric this GrayKey hacking tool will take much more time and probably will be useless, it might take years.
