OTP types

OATH allows generating an OTP based on a shared secret. There are two types of OTPs:

  • time-based OTP (TOTP): A TOTP is renewed after a fix amount of time, for example 30 seconds. 
  • event-based OTP (HOTP): An HOTP is valid per authentication. After authentication a new OTP is generated. 

Nexus authentication platform

Nexus authentication platform Smart ID Digital Access component supports OTP token authentication based on OATH – for hardware and software tokens – as well as self-registration for OATH-compliant mobile applications.
