About this app

This is a free security app that allows you to safely use Keiyo Bank's personal internet banking.
You can use the function to confirm and approve transaction details (transaction authentication) and the function to display one-time passwords.

●People who can use it
Customers using Keiyo Bank personal internet banking

●What is transaction authentication?
This is a method of confirming that transaction details have not been tampered with during communication. By having the customer perform the approval operation, unauthorized remittances can be prevented and the service can be used more safely.

●What is a one-time password?
A one-time password is a variable password that is updated after a certain amount of time. Since it is difficult for third parties to misuse it, it has the effect of increasing the safety of transactions.
