Key Features iShield Key Pro

  • PIV (Personal Identity Verification) functionality utilizes Public Key Infrastructure (PKI) and PKCS #11 standards for secure digital certificate and private key storage. It supports authentication, digital signatures, encryption, and physical access, enabling Windows logon via local accounts or Microsoft Active Directory, even with BitLocker encryption.
  • HOTP provides an event-based two-factor authentication method, suitable for web services without WebAuthn support. It combines a shared secret key with a counter-based one-time password, ensuring security for both online and offline applications without the need for internet connectivity.
  • TOTP (Time-Based One-Time Password) provides a time-based two-factor authentication method, ideal for web services without WebAuthn support that require an additional layer of security. It generates a unique, temporary password by combining a shared secret key with the current time. The iShield Key supports up to 42 TOTP slots. Use our Android TOTP App to generate temporary passwords with an NFC-enabled Android phone and your iShield Key Pro.
