The LINE Corporation has enabled passwordless authentication for users trying to gain access to the LINE app on an iPad. The feature is based on the latest FIDO authentication protocols, and will allow people to log in using the biometric information stored on a smartphone that has been linked to their LINE account.
To take advantage of the new feature, users must first install LINE app version 10.18.0 or higher on both their iPad and their smartphone. They must then make sure that their biometric information is registered to the phone, and that the phone is paired with their LINE account.
After that, they will need to log into the LINE app on the iPad and select the “Log in with smartphone” option to connect the iPad to the phone. The user will need to verify their phone number as part of the process, and will also need to enter a six-digit verification code the first time they log in. That code will be sent to the paired mobile phone.
LINE indicated that it will be bringing a similar smartphone login feature to the desktop version of its platform later in the year. It will then allow users to migrate LINE accounts and sign into LINE family services with biometric authentication in 2021.
While the feature is designed to make the LINE app more user-friendly, the Corporation stressed that it did not want to do so at the expense of user privacy. Any biometric information remains on the user’s smartphone, and is never stored on LINE’s app or servers.
LINE is a long-time proponent of FIDO’s authentication protocols. The company joined the Alliance’s Board of Directors in 2017, and later mentored one of the winning teams during a 2019 hackathon that was carried out by the organization’s Korea Working Group.
