• KeepassXC: local storage, you’re responsible for backing up and keeping your password database file safe. (Keepass is a open standard for passwords, so you can use any client that supports keepass files, not just KeepassXC)
• Bitwarden/Vaultwarden: web-based server-client password manager. You can use bitwarden.com if you want to just set it up and leave it.

Stay away from any password manager that’s sponsored on YouTube or that’s proprietary (if you can’t find the source code anywhere, stay away!)
