OTP authenticators

A one-time password (OTP) authenticator is a mobile app, computer program or security hardware device that produces a single-use password or PIN.

OTPs are passwords that are valid for only one transaction or login session, and they are much more secure than static passwords. OTP authenticators are often used as part of a two-factor or multifactor authentication.

Nexus offers both software-based and hardware-based OTP authenticators, such as:

  • Mobile apps that generate time-based one-time passwords (TOTPs).
  • Computer programs that generate OTPs.
  • OTP tokens that are integrated into web browsers.
  • OTPs that are sent via text message.
  • OTP display cards.
  • OTP display key fobs.
