IIJ Launches One-time Password Application "IIJ SmartKey"

Develops free, standard-compliant application for iPhone and Android devices

April 3, 2015

TOKYO-April 3, 2015-Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI, TSE1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced that it launched the free "IIJ SmartKey" one-time password management application in the App Store and Google Play on April 1, 2015. The new application is an effective means of strengthening the security of user authentication for web services.

One-time passwords are disposable passwords that are valid for use only a single time. When verifying online identities for e-commerce transactions, social networking services, and the like, user authentication typically consists of inputting a user ID and a password. By adding a one-time password to this process and thus implementing two-factor authentication (two-step verification), the level of security can be increased, preventing unauthorized logins by impersonators and other breaches. IIJ SmartKey is a one-time password generation application for smartphones. The application can be used for two-factor authentication with a variety of web-based services that comply with the TOTP(*) standard. Multiple one-time passwords can be centrally managed on a single device.

  • (*)TOTP (RFC6238 Time-based One-time Password Algorithm): A standardized time-synchronized one-time password authentication technology.

Development background

The goal of two-factor authentication with one-time passwords is to prevent unauthorized use of passwords by third-parties. It is frequently employed in online transactions, such as Internet banking, that require the use of advanced security measures. Recently, general awareness of security has been on the rise, and one-time password authentication is increasingly being deployed in web-mail services and social networking sites. IIJ strove to meet these needs for stronger security and to enable customers of all sorts to feel secure while accessing online services when it developed the free application; the design and ease-of-use of the application were given full consideration.
