One-Time-Passcode authentication via SMS


One of the most diverse authentication platforms on the market is now that much easier to use. Entrust, in a relationship with Clickatell, provides one-time-passcodes (OTP) to mobile devices via SMS. Often known as soft tokens, this adds yet another authenticator to the Entrust IdentityGuard versatile authentication platform.

“Working with Entrust, we give customers more choices in how they deploy strong authentication. A one-time-passcode solution for mobile devices can help in reducing security access costs and offer an unprecedented level of convenience,” explains Pieter de Villiers, CEO, Clickatell. “SMS OTPs can offer customers an easy, convenient way to gain secure access to financial accounts, corporate environments and government networks via the proven second-factor authentication method.”

The joint marketing agreement will provide technology to enable single or multiple one-time-passcodes to be sent to a mobile device. Sent directly to the end-user’s mobile phone, Entrust IdentityGuard will automatically issue a configurable number of OTPs via Clickatell text messaging. These passcodes can be used as a second factor of authentication with Entrust IdentityGuard – all with the convenience of using a user’s existing mobile device. This service also provides automatic refresh of the passcodes and even enables authentication while out of mobile network range.

Entrust IdentityGuard enables organizations to layer security – according to access requirements or the risk of a given transaction – across diverse users and applications. The platform’s authentication options include strong username and password, IP-geolocation, device, questions and answers, out-of-band one-time-passcode (delivered via voice, SMS or e-mail), grid cards, eGrid cards and a range of one-time-passcode tokens. Entrust IdentityGuard also provides multiple methods of supporting mutual authentication, including picture and caption replay.
