Required settings for logging in to LINE for iPad or PC with your smartphone's unlock method

To be able to log in to your LINE account on an iPad or PC using your smartphone's unlock method, you need to:

• Set an unlock method on your smartphone.

• Allow your smartphone's unlock method to be used for logins in the LINE app.

Setting an unlock method on your smartphone

For iOS:

Use Touch ID on your iPhone or iPad

Use Face ID on your iPhone or iPad Pro

For Android:

Check your phone manufacturer's website for details on how to set an unlock method.

Note: LINE will never save your unlock method.

Allowing your smartphone's unlock method to be used for logins in the LINE app

1. Tap the Home tab > Settings > Account.

2. Tap Face ID/Touch ID for iOS or Device unlock method for Android > Enable.

You'll know setup is complete when you see Unlink in the field for Face ID/Touch ID or your smartphone's unlock method.

Using your smartphone unlock method to log in is more secure because you are the only person who can use it.

You can increase your account security even more by not allowing logins with an email address and password. To only allow your account to be logged in to with your smartphone's unlock method or a QR code, tap the Home tab > Settings > Account and turn Log in with password OFF.

Note: Turning Log in with password OFF will not log you out of any devices you're already logged in to.

"This message can't be displayed" appears and I can't see sent/received chat messages

If you see any of the following messages after transferring your account on a smartphone, you may not be able to view past chat messages.

- "This message can't be displayed"

- "This message wasn't backed up and restored from your previous device. Unfortunately, there's no way to read it on your current device."

- "Unable to display message as it couldn't be decrypted."

The messages above appear when:

• You transfer your account to a device with the same OS (e.g. iOS to iOS) without backing up and restoring your chats.

If you back up your chats on your old device before transferring your account, you can view them on your new device. For the steps to do so, see this Help article.

• You transfer your account to a device with a different OS (e.g. iOS to Android).

Note: You cannot transfer your past chats.

• You receive chat messages while transferring your account.

Any such messages cannot be transferred to your new device. For more information, see this Help article.

If any of these messages appear and you cannot view your past chat messages, there is unfortunately no way to re-display them. In this case, please ask the other person in the chat to send you any old messages that you need.
