With Verisec Mobile, all the insecurity and hassle with passwords becomes history. Two-factor authentication (2FA) and one-time passwords (OTP) is just the beginning; Verisec Mobile gives you a whole new level of security, control and user convenience. Tap into the power of your smartphone with new technology that goes beyond traditional tokens. The Verisec Mobile app always displays a description of what you are about to approve, such as logging in to your corporate network or signing a value transaction. All you have to do is enter your PIN in the app and the action you have requested is automatically processed, though a separate secure channel. No manual transfer of codes or passwords between the phone and the web browser is ever needed. Password hassle and phishing-attacks becomes a thing of the past as the “see what you sign” feature offers a new layer of security and control. When the smartphone cannot be connected to the Internet, Verisec Mobile can also be used in offline mode, as an easy to use one-time password (OTP) generator. Please note: In order to use Verisec Mobile the organisation or web service issuing your credentials must have the server-side component VerisecUP installed. For questions about how to use the app, please check with the issuer of your credentials. For more information about VerisecUP Authentication Service, please visit www.verisecint.com
