By enabling this setting, you can perform login authentication using an authentication application such as a smartphone application.
How to Use
A QR code and a registration code will be displayed when the “Two-factor authentication” setting is enabled.
Register these to the authenticator app.(Google Authenticator or Microsoft Authenticator are available)
The next time you log in, use the one-time password obtained from the authentication app in addition to your ID and password.
If you are unable to log in due to deletion of the authentication app or change or loss of your device, please reset your password by clicking “Forgot your password?” on the login screen.
