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 want to use it on the devices I control. If that is the case, how can I just carry the database and not the software?
It’s very easy, you’ll install KeepassXC on both pcs, and as you can read here from their docs, the first time you’ll create a brand new database (usually a .kdbx file). You can create as many as you want actually, and you can move or copy those files around, so experiment without worries. Any compatible keepass software will be able to open these databases (as long as you have the secrets needed for each one like its key or its master password…).
KeepassXC also remembers the last file locations, so the next times you open the program it should look for the db in your pen drive and immediately ask for the master password. The KeepassXC in your different pcs are indipendent, but you can edit a common file, just like we would with a word document for example.
