LINE is introducing FIDO authentication to improve security for account registration, login, and transactions across its various services. Potential use cases for FIDO include social login, setting confirmation, desktop app login, transaction authentication for payments, IoT control, and hands-free IoT control. LINE plans to integrate FIDO using UAF and FIDO2 standards and deploy an authentication platform to serve as an identity provider across its services and other apps and websites by 2020.
