----------------------------------------
It is a software token application that supports the security function "one-time password" of Yahoo! JAPAN.
This application generates a "one-time valid password (code) that changes every 30 seconds".
If you set a "one-time password", authentication with this "code" will be added to your usual "Yahoo! JAPAN ID and password".
◇ Easy operation for smooth authentication!
You can check the "code" immediately by launching the app, so it does not take time to authenticate.
◇ Set a one-time password for peace of mind!
In the unlikely event that someone else knows your password, you can rest assured that the "code" will only be known to the app owner, so no one else will be able to log in without permission.
◇ Main features
・ Smooth authentication (code copy function)
・ Code issuance even in places where there is no radio wave
・ RFC standard HOTP is adopted
See the guide below for details.
