I understand that if you use Veracrypt on a USB drive, unless you know the password or passphrase, you cannot access the contents of the drive. The part that is throwing me off is, do you need to have Veracrypt installed on a computer to unlock the drive? Otherwsie, you cannot access it, correct? I ask because if I wanted to access the drive on a computer that does not have Veracrypt installed, it won't work, right? If that all wrong, please kindly explain to me how it works.
