SAFE-Key by BiObex is a multi-function hardware security device that provides strong two-factor authentication (2FA) for secure access to personal or corporate information, encrypted email communication, and file protection. It uses SAFE (Strong Authentication Front End) Technology to tie the user's password and cryptographic secrets to the authentication transaction. The device is designed to secure logins, encrypt directories and files, protect passwords, and encrypt email content between SAFE-Key holders. It transmits evidence for both authentication factors in a single encoded password packet that is intertwined and encrypted.
