It is a harwdware USB key that contains the chip itself. Bittron is complemented by the user's mobile app. The app authenticates the user's login - the user must confirm the login via Bittron by entering a PIN or biometric data (fingerprint). If the user moves away from the connected device (leaves the desk), Bittron automatically disconnects the connected session. ProID Bittron is a state-of-the-art solution for secure work identity and login to computers and systems. It enables two-factor authentication and Smart Card Logon to VPNs or clouds - it works like a smart card. The mobile app is only for ProID customers who use ProID Bittron. Without this connection, the app is not functional.
