tPro OTP

tPro OTP is a small and user-friendly device that generates and automatically inputs one-time passwords, based on the HOTP (HMAC) algorithm. There is no need to rewrite passwords from a card or a screen, so they can be much longer which increases security.

tPro OTP may be used in banking, but it can have other purposes too. Apart from verifying transfers and operations, it can be useful in all the situations, where a username and a password are not enough.

No drivers are required to use tPro OTP, because it works out of the box. No matter if it’s connected to a PC, a tablet or a smartphone. When a user has to write a one-time password, he just pushes the built-in button and the token generates and inputs the password into the chosen place. The device was designed in a way to make sure that the private key that generates passwords never leaves the device. This means that the private key cannot be copied, even with the access to the computer’s memory.

  • Built-in button
  • USB power supply
  • Highly secure – tPro OTP is equipped with both the
  • event-based RFC 4226 and the time-based RFC 6238algorithms.
  • Advanced protection is enabled by two factorauthentication: something users have – the device, andsomething they know – their PIN.
  • Universal access – as an NFC-enabled USB HID device,tPro OTP can be used on smartphones, tablets and PCs with Windows, Mac OS X, Linux and Android operatingsystems without the installation of any additional drivers.
  • Easy to deploy – tPro OTP can be easily integrated into existing solutions through platforms (Comarch Identityand Access Manager DRACO or any other OATH-compliant solutions), libraries (Java, .NET, Node.js, PHP) or infrastructure
    services (Radius).
  • Easy to use – once users insert the tPro OTP token into a USB port, they just need to press and release the built-in
    button to access onboard security applications.
  • Customizable – the tPro OTP tokens are designed and manufactured by Comarch Technologies and can be customized with a logo and other branding.
