Why It Matters
In order to improve account security and user login experience, LINE has introduced pass key technology that complies with modern information security standards.
LINE recently launched the "Passkey" function, which allows users to complete identity verification through facial recognition, fingerprint recognition, or device unlocking without entering a password when logging into a LINE account. Especially when changing mobile phones, it can reduce the trouble of being unable to successfully transfer accounts due to forgotten passwords. However, in order to use this feature, you must first complete the email settings of your LINE account, and the LINE App must be updated to version 26.17.0 or above.
According to LINE's official support center, when users change their mobile phones, or need to log in to LINE on a new device due to loss or malfunction of their mobile phones, they may have been unable to successfully transfer their accounts due to forgotten passwords in the past. Now by creating a pass key in advance, you can use the device's biometrics or screen unlock function to complete identity verification, reducing the hassle of entering passwords.
LINE pointed out that the pass key has three major advantages: security, login convenience and cross-device synchronization. First, since there is no need to create or store traditional passwords, it helps reduce the risk of password leaks and phishing scams. Second, there is no need to remember an email account or password when logging in. You can complete identity verification just like unlocking your phone.
In addition, the pass key also supports synchronization between devices. As long as you log in to the device with the same Apple ID or Google account as the one used to save the pass key, the pass key can be synchronized safely, reducing the trouble of resetting when changing phones.
However, LINE officially reminds that before creating a pass key, the account must first complete the email settings; in addition, each LINE account can create up to 10 sets of pass keys, and each device can only create one set. Users can also manage or delete the created pass keys as needed.
As for the setting method, users can open the LINE App, go to "Settings" > "My Account" > "Pass Key", and then follow the on-screen instructions to complete the setting through facial recognition, fingerprint recognition or device unlocking.
LINE also reminds users that they should create a pass key in advance before changing their mobile phones. In addition, the pass key is mainly used for identity verification when logging in. Therefore, it is recommended that before changing mobile phones, you should still follow LINE's official instructions to complete account transfer preparations and chat history backup to avoid losing important conversations. In addition, since new functions are gradually opened, the actual availability still depends on the user's device and the LINE App display.
