ワンタイムパスワード (One-time password) is an Android application developed by NTT DATA CORPORATION. This app generates passwords that change every minute, providing an extra layer of security for various services. By combining the one-time password with a username and fixed password authentication, users can enhance the security level of websites and other online platforms.

To use this app, users need to apply for it through the service provider they are using, such as financial institutions. To prevent the theft or replication of app data, this app introduces a feature that prevents data transfer to other devices. Therefore, if users change their device or uninstall and reinstall the app, they need to perform the necessary procedures in advance through their service provider. Failure to do so will result in the inability to use the app. For inquiries about the required procedures, please contact the service provider's support center (e.g., financial institution).

With ワンタイムパスワード, users can enjoy the convenience of generating secure passwords that change frequently, enhancing the overall security of their online accounts.
