One-Time Password (OTP) TokensOATH-compliant Authentication Tokens, Keypads and Cards

Our OATH-compliant One Time Password tokens are a simple, secure and highly cost-effective way of deploying stronger user access control within your organisation.

OTP tokens are one of the simplest methods of strong authentication and are very commonly deployed by organisations looking for a quick and effective way of boosting their login security.

OTP Types

OTP tokens come in two types: event-based (HOTP) and time-based (TOTP). Event-based OTP tokens generate new codes at the press of the button and the code is valid until it is used by the application. Time-based OTP tokens generate codes that are valid only for a certain amount of time (eg, 30 or 60 seconds), after which a new code must be generated.

We also offer a keypad token which provides PIN-protected OTP as well as challenge-response functionality. In challenge-response mode the user must enter a challenge code (eg, displayed by the application) and the token generates a response which the user enters back into the application. Use this token for challenge-response authentication, e-signature generation and transaction signing.

OTP Authentication Server

Deploy OTP tokens in conjunction with our Identity & Access Management (IAM) system and give your organisation total control over issuing and revoking tokens and assigning tokens to users. Our SmartSign solution provides IAM facilities and a multi-factor authentication server and token management system.

Branding and Customisation

Our products use the specifications listed below as standard, but we are able to supply tokens in other configurations to meet the needs of your project. All of our OTP tokens can be customised with your logo or other artwork. Please get in touch to discuss your requirements. Please note that longer lead times and minimum order quantities apply. See the table below for further details of the different customisation options available for our OTP tokens.
