I’ve always loved Keepass, however I moved away from it in 2012 as it and any file based vault has brute forcing issues. You need to track every copy of it that has been made and if any copy falls out of your hands, like if you lose a device, you need to do a password rotation on 100% of your passwords. Since its a file, its not possible to prevent brute forcing.
TIL… Thanks.
EDIT: Been playing with it a bit now and if it uses keepass as the DB the advantage I see right now is that having it in Nextcloud means automatic sync, and there are several autofill and syncing apps for various OSes and password sharing and automated checks for breaches. It’s probably a better option for anyone with Nextcloud than going the Keepassxc/syncthing route.
