Getting started with KeePassXC # Install KeePassXC and launch it. Click on the Database menu and select “New Database.” You will be prompted to save your password database. Note that you can move the password database file later to wherever you like on your hard disk, or move it to other computers—you will still be able to open it using KeePassXC and the password, or keyfile, you specified before.
