When we talk about Android mobiles, we do it about devices to which we can connect a multitude of other devices through their ports, both physical and wireless. OTG compatible USB ports can manage USB keys like a computer, and if you usually use them on your mobile, it does not hurt to protect these in the way that we explain today.
USB sticks are usually used to copy all kinds of data, from files with multimedia content to documents of a certain value. In any case, if what we copy in these memories is sensitive to us, and we believe that they need extra protection, we can always protect them from access by third parties.
Prevent access to these USB keys
Normally we can connect this type of keys through the USB type C or microUSB connector as long as it is OTG, with which we can enter the file system in the same way that we would from a PC. In this case what we propose is to protect the reading of these keys by third parties thanks to an app that we can install on the mobile. An app that is used for different cases in which we need to add an extra layer of security.
This app is called USB Lockit, and as its own name indicates, it allows us to lock the USB key. For this, a password is added to it that we can only activate and deactivate with this same app when the USB key is connected to our phone. Therefore, all we have to do once we have installed the application is select the USB key that is connected to our phone, and activate the protection by adding a password. Once we do it, anyone who wants to access it will not be able to do so, since their access will not be available from anything other than the application itself.
And of course, to unlock access you need to reopen the app with the memory connected to your phone , and unlock it by entering the password that we created earlier.
Secure key on any device
The most interesting thing about this app is that once we lock the key on our mobile, the lock remains independent of the device we use . So if it falls into the hands of third parties, they will not be able to access the data if they do not go through our mobile before and enter the password that we have applied. An app that works with all USB flash drives on the market, as long as they are formatted in FAT32 or exFAT .
