No I mean the password manager itself has no 2FA. It is impossible to implement 2FA on this kind of password manager. Almost all password managers like 1Password, Bitwarden, etc. implement 2FA so even if your master password is compromised (e.g. by a remote keylogger), an attacker can't get into your vault without physical access to one of your existing devices.
