Mobile one-time passwords (OTP)

The mobile app Smart ID Mobile App supports time-based and event-based one-time passwords (OTP). 

Smart ID Mobile App works in offline mode and offers extra security compared to other mobile apps for two-factor authentication, since the user must authenticate in the app with a PIN code or biometric validation with fingerprint or face recognition, before receiving the OTP. 

For more information, see About one-time passwords (OTP) and One-time passwords (OTP) in Nexus' Digital access platform.
