I self host Vaultwarden at home on my server and it uses 2FA for logging into the system to access your saved passwords. It’s easy to set up and I use a Yubikey for mine. I use Docker to do this myself. It’s an adaptation of Bitwarden and is compatible the same Bitwarden app and browser plugins. Having everything on your own system ensures that it doesn’t go to the corporate controllers out there. Plus, you can find the source on Github for Vaultwarden so you can go over it if you are unsure about the security of it. :)
