The SASe USB Key adopts the USB 1.1 standard, with a transmission speed of 12 Mbps, and features water resistance. It operates without requiring additional driver installation.

The SASe USB Key is the world’s first FIDO Key that integrates PUF (Physically Unclonable Function) and FIDO2 functionality. It supports all FIDO-compatible services, including Microsoft Azure AD, Facebook, Google, and AWS, and can be used for two-factor authentication or passwordless login.

Additionally, IIST leverages the dynamic PUF generation feature to register multiple application root keys, further expanding the SASe USB Key's capabilities at the application layer. These include password management (including one-time passwords), file encryption and decryption, and API key management, providing independent security services."
