GrayKey is the magic device that does this. We heard about it last month and even saw it in pictures. Now, more details about how it works, especially about how long it takes to do its job .
As Matthew Green, professor of cryptography at Johns Hopkins, points out, the GrayKey only needs a few minutes to unlock an iPhone that has a four-digit number as its password. In the worst case, it took 13 minutes to get access to the iPhone. As the password becomes more complex, the time increases.
- 4 digits: about 6 minutes
- 6 digits: about 11 hours
- 8 digits: about 46 days
- 10 digits: about 4629 days
As you can see, the longer the password, the harder it is for a device to gain access to the iPhone by brute force. By default iOS offers us a six digit password, but we can modify it and make it more complex (or simple) if we want. In fact, changing the security code of the iPhone or iPad is really easy.
What kind of code to use? The most recommendable is to use an alphanumeric code, that is, one that contains other characters such as letters or symbols in addition to numbers. At the time we saw how to use an alphanumeric code. Try to make it have at least 10 characters, randomly and combining letters with numbers and symbols . With Touch ID and Face ID, using such a complex code should not be a problem, since in most cases we will be able to unlock the device using one of these authentication methods, without having to resort to the code.
