About this app

This is an authentication app used for Okasan BANK's internet banking.
You can issue or generate app tokens (one-time passwords that are valid only once) on your smartphone, which are necessary for transactions such as transferring money or changing your PIN.
In addition to normal authentication, Okasan BANK's authentication app also supports transaction authentication, which is a stronger authentication method.

------------------------
●Available services
------------------------
・Normal authentication
Generate and display the app token (one-time password) required when making transactions on the website or trading app. Customers enter the displayed app token on the website or Okasan BANK trading app.

・Transaction authentication
Transactions made on the website or transaction app will be notified to the authenticator app. Confirm the transaction details and execute it within the authentication app to complete the transaction. This is a strong authentication method that is effective against extremely malicious techniques such as hijacking communications after a customer logs into a website or Okasan BANK trading app and falsifying transaction details.
