③ Authentication by App
One-time password authentication is a method that involves downloading an authentication app to your smartphone and using a
disposable password generated by the app. The one-time password is disposable and will be invalid the next time you log in. Even if
someone steals it, the password changes every 30 seconds and will expire in a short time.

- People who cannot or do not want to use screen lock functions
Since you use an authentication app, you do not need to set up screen lock on your smartphone or PC.

- People who use multiple devices such as smartphones and PCs

Since the device that can log in to the ExpoID is not limited, you can log in to the Expo ID on multiple devices such as smartphones
and PCs.

For how to set it up, refer to “2.2-C: Using Authentication by App".
