Your password and email address are used to transfer your LINE account and verify your identity. By registering and checking them in advance, you can prevent issues when switching devices or logging in. If you forgot your password, you will need to change it.
Be advised
- You cannot change your email address or password for 24 hours after transferring your LINE account.
About passwords
A password is used to verify that the LINE account belongs to you. You may be asked to
enter your password when transferring your LINE account or logging in to your sub device.
You can check
in your settings whether a password has been registered or not.
However, the actual password cannot be viewed
once it has been registered.
Useful info
- Your password must contain 8-20 non-repeating half-width characters, and be a combination of at least three of the following types: uppercase letters, lowercase letters, numbers, and symbols.
