I would find it very nice if bitwarden would automatically log you out after say 5 attempts of entering a wrong master password to unlock the vault in your desktop app and browser extension. This would be similar to the PIN or fingerprint unlock on the mobile app, where 5 wrong attempts lead to a logout.
Meaning that after 5 wrong attempts your data gets deleted from your system and you would need to log in again using a 2fa code.
This is similar to the feature request for a PIN also on the desktop app. But I would find it nice to have the automatic logout in all settings and not only when using PINs.
