First, set a backup PIN on your old device.

A backup PIN lets you transfer your chat history when you transfer your LINE account.

Even if you haven't backed up your chat history beforehand, you can transfer your chat history from the last 14 days regardless of the OS when you set up a backup PIN.
Note: If you've backed up your chat history beforehand, you can only transfer your entire chat history between the same OS. Refer to the following Help article for details.

Backing up your chat history

For the steps to set, check, or reset your backup PIN, refer to the following sections.

Setting a PIN code

1. From the Home tab, tap Settings > Backup and transfer > Chat history backup/Back up and restore chat history.
2. Tap Back up now or Create backup PIN and back up chat history.
3. Enter a six-digit number.
4. Tap the arrow.

Checking/resetting a backup PIN

1. From the Home tab, tap Settings > Backup and transfer > Chat history backup/Back up and restore chat history.
2. Tap Backup PIN.
Note: If you're asked to unlock the screen, use the unlock method you have configured on your device, such as your passcode or biometric identification (e.g. fingerprint, face). Do not use the password registered to your LINE account.
3. Check the PIN you currently have set.
4. To change your PIN, tap Change.
5. Enter your new PIN, and tap Change.

Make sure your backup PIN is a secure combination to prevent it from being used by someone else without your permission.

Here are some tips for setting a hard-to-guess backup PIN:
• Don't use consecutive numbers (e.g. 123456).
• Don't use the same number repetitively (e.g. 111111).
• Don't make the PIN your birthday.
