============================== Strong 2-factor Authentication ============================== **Tokens** StoredSafe is designed to store your most sensitive information. That’s why two factor authentication is required and included as part of StoredSafe Secure Platform. Our recommended and currently supported implementation are Google Authenticator and Yubico’s YubiKeys as client-side hardware token in addition to a strong passphrase. **HSM** To further improve security, YubiHSM (Hardware Security Module) is incorporated in the platform to store cryptographic keys for all YubiKey hardware tokens and secret keys for Google Authenticator. This provides an excellent authentication server for YubiKeys and Google Authenticator . This enables our customers to be independent of Internet, and critical networking services when in need of access to critical data during a disaster.
