As an extension of the HMAC-based one-time password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard RFC 6238. Support: Free and proven online support under: reiner-sct.Time-based one-time password ( TOTP) is a computer algorithm that generates a one-time password (OTP) using the current time as a source of uniqueness.Warranty: 2 years (no warranty on batteries).Scope of supply: REINER SCT Authenticator with 3x AAA batteries and quick guide.Weight (without/with packing) approx.: 80 g / 200 g.Packing dimensions (L x W x H) approx.: 201 x 149 x 47 mm.Product dimensions (L x W x H) approx.: 102 x 62,5 x 19 mm.Special colours, customised printing: On request, minimum order quantity.Housing colours (standard): Yellow/white.5 years (basis for calculation: 500 TOTPs per year, the actual life depends on the respective time and type of use and the ambient conditions) Power supply: 3x alkaline-manganese batteries, size: AAA / IEC LR03, replaceable.The TOTP codes and accounts remain saved without battery supply. Code saving: In the persistent memory.Real time clock backup: Backup of the real time clock for approx.Average deviation < 1 ppm by automatic calibration in time synchronisation. Real time clock (RTC): High-precision quartz real time clock.Display: 1.77 inch TFT colour display 128 x 160 pixels.Operating display: By TFT colour display.Camera: CMOS colour camera with OmniPixel3-HSTM technology, aperture angle: 57°.Numerical keys / function keys / special keys: 10 / 3 / 2 rubberd coated keys.Menu functions: Accounts, Reader (identification), Settings (including battery status), user PIN.Time synchronisation: unidirectionally using an encrypted QR-Code.Code saving: in the secured hardware chip.Supported TOTP algorithms: SHA 1, SHA 256, SHA 512.Supported procedures: OATH-TOTP according to RFC 6238.Device category: Hardware TOTP generator.The REINER SCT Authenticator uses a built-in camera to recognize the authentication data displayed by the online platform in the form of a QR code at lightning speed and assigns it to an account. In addition, its function can be secured with a PIN protection. He works without an internet connection and therefore cannot be attacked online. The REINER SCT Authenticator securely stores the electronic keys for the logins in its hardware and generates the TOTP one-time passwords with high precision every 30 seconds. Hardware-based TOTP generators offer the highest security. However, due to the limited security of smartphones, the TOTP can be spied on easily. Authenticator apps on smartphones are often used for this. The most common method is the time-based one-time password method, called TOTP. The Federal Office for Information Security (BSI) expressly recommends the use of two-factor authentication! This so-called two-factor authentication (2FA) protects your user account against misuse and identity theft to a high degree, even if the user name and password get into the wrong hands. Almost all leading online platforms therefore offer the option of additionally registering with another component. Entering your username and password when you log in is no longer secure.
