Cross channel OTP One time password API

What is Cross Channel One Time Password?

Cross channel One-time password – or OTP –  is an automated solution that allows users to log in to a session or transaction through the verification of a random code. The code is sent through a channel different from the one through which the request was made. In order to validate the client’s identity, the client must be able to access the email account or be in possession of the registered mobile phone to which the SMS code was delivered. The code has a short lifespan and can only be used once, providing added security.


  • Add an additional layer of authentication to a web-based service to protect it against fraudulent login attempts.
  • Avoid the security deficiencies associated with static password-based authentication.
  • Verify customer access to an additional digital channel, as a multi-factor authentication.
  • Give the possibility to define the security criteria of the password, such as the lifespan and the number of characters in an easy and efficient way.
