Useful info

Biometric logins are only supported on iPads.

You can log in with the biometric information (e.g. face, fingerprint) registered to your main device when you use an iPad as a sub device with the same LINE account as your main device.

By logging in with your biometric information, you can manage your LINE account more securely than with using an email address and password.
Note: Your biometric information isn't saved on the LINE app or servers.

For the requirements and preparations for logging in with biometric information, refer to the following Help article.

How logins with biometric information work

When logging in to LINE with biometric information for the first time:
1. Start LINE on your sub device.
