Bitwarden has just launched a new multi-factor authenticator app called Bitwarden Authenticator, which is available for iOS and Android devices.
The app uses time-based one-time passwords (TOTPs) for accounts registered by scanning a QR code to provide users with an extra layer of security during authentication.
