Protectimus Ultra by Protectimus Ltd is a reliable security solution designed for generating one-time passwords (OTPs) using a request-response algorithm. It is ideal for securing sensitive system areas. The secret key is generated during token activation, ensuring it is unknown to the manufacturer. Protectimus Ultra operates in request-response mode, which uses time as an additional parameter to prevent repeated use of responses. It features theft protection with a PIN on the token, ensuring security even if stolen. Protectimus Ultra supports OTP generation algorithms OCRA and TOTP, with arrow buttons to switch between them. It includes status indicators, locking after 6 incorrect PIN entries, unlock code generation, and PIN change functions. The device dimensions are 7.02 cm × 4.52 cm × 0.32 cm, and it can generate OTPs of 8 or 12 characters in length. Protectimus Ultra can be customized with a company's logo and color, with delivery times depending on lot size, token availability, postal service, and additional visual features.
