Vaultwarden vs KeePassXC for extreme security (lemmy.ml)

I was thinking about how all of my passwords are compromised if I have malware on my system. It made me wonder, does Vaultwarden or KeePassXC/KeePassDX offer better protection on a malware infected system?

Vaultwarden

Only accessed locally via LAN/VPN
Set up for 2 factor authentication using WebAuthn (FIDO)

KeePasssXC/KeePassDX

Synced locally via syncthing
Set up for 2 factor authentication using HMAC-SHA1 Challenge-Response
All clients blocked from internet access

I don't use browser extensions and I manually copy/paste my passwords to fill in entries.

KeePass has good memory protection, but the 2FA can be read from USB and doesn't change every time the database is decrypted. Vaultwarden enables the more secure FIDO2 2FA, but to my knowledge has less secure memory management as the entire entire database is decrypted on unlock.

Maybe I’m misunderstanding something then, what’s the private key embedded within the client API’s profile response?

[–] pupbiru@aussie.zone 1 points 2 days ago

which endpoint are you referring to?

there are passwords exchanged when using the vault management API, but AFAIK that’s for local access (eg CLI talking to the app)

i’m no expert on the specifics of the API; just in the description they give: https://bitwarden.com/help/what-encryption-is-used/

Bitwarden always encrypts and/or hashes your data on your local device before anything is sent to cloud servers for storage. Bitwarden servers are only used for storing encrypted data.

…

PBKDF2 SHA-256 is used to derive the encryption key from your master password

this is exactly the way this should be done. any deviation from this formula by a password manager with a server component should be viewed with extreme scepticism
