I wanted to switch to KeePassXC and I wanted to download it on a encrypted USB drive for portability. I know I can do this on Windows, but will the password manager work on other OSes? I switch between Windows and Linux, and I want to make sure that I can do it on both. I read an online article that says its possible, but you need to make sure you have a certain file on the drive for it to work?

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.
