Mobile UniOTP


Mobile UniOTP is a mobile application supporting event-based, time-based and challenge-response generation of one-time passwords. Mobile UniOTP software can only be used in conjunction with UniOTP Server, and supports iOS and Android.


Mobile Application

Mobile UniOTP, unlike UniOTP 300 and 500, is a mobile application instead of a device, with the benefit of utilizing existing mobile devices for OTP authentication without the need for deploying additional devices.


Event- and Time-Based

Mobile UniOTP is both an event-based authenticator, displaying a HOTP (event-based one-time password) onto the display after pressing the generate button, and a time-based authenticator, displaying a TOTP (time-based one-time password) every 60 seconds onto the display.


Challenge and Response

Mobile UniOTP also incorporates a challenge and response token system. The correct response, from a server-side generated token entered into the application, is required to successfully authenticate. A challenge and response system reinforces the authentication process, as only the appropriate user can generate the correct response in order to successfully authenticate.



Dynamic passwords coupled with existing authentication systems overcome the limitations of static passwords, whereby successful authentication requires both the correct credentials and the generated one-time password unique to that instance, with no two identical OTP ever generated.


Valid Once

Passwords generated by the token are only valid for use once, after which the generated password becomes invalid.


Cryptographically Random

Passwords are randomly generated, and are infeasible to reproduce like-passwords from the given allotment of possible passwords that can be generated.


Ease of Use

Authenticating with one-time passwords simply requires the user to enter the password read from the mobile device, without the need of remembering or storing passwords.


Report of Loss

Lost or stolen devices can be reported and deactivated from the system immediately, allowing risk control.


Malware and Interception Safe

Malware and interception attempts to gain access are not possible, even in the possession of a previously-used OTP, due to the dynamic nature of one-time passwords.


Brute-Force Resistant

Due to the dynamism offered by one-time passwords, brute-force attacks are rendered impractical.


Cost-Effective and Economic

Both the ease of the mobile application software deployable onto existing mobile devices, and the savings incurred from avoiding the deployment of additional devices, Mobile UniOTP offers a highly cost-effective OTP authentication solution.
