Registering/checking/changing your password
Be advisedTopics covered
- Making a secure password- Registering a password
- Checking/changing your password
Making a secure password:
When setting a password, it's important for it to be secure and difficult for other people to guess.
To set a secure password, make sure it:
• Is a complex combination of upper and lowercase letters, numbers, and symbols.
• Doesn't use personal information, such as:
- Your nickname or initials.
- The name of a child or pet.
- A birthday or anniversary of you or a loved one.
- Your address.
• Doesn't use typical strings of characters or words, such as:
- Easy to guess words or phrases (e.g. "password" or "iloveyou").
- Consecutive letters or numbers (e.g. "123456" or "abc123").
- Strings that follow the keyboard layout (e.g. "qwerty" or "1q2w3e").
Important: 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, lower case letters, numbers, and symbols.
For the best online security, make sure not to recycle passwords, but rather to set and safely manage a different passcode/password for each online service you use. Making use of software and OS features to manage your passwords is another way to achieve secure password creation and management. You can get a complex password with ease and peace of mind by using a software feature to automatically generate a password. If you use software to manage your passwords, you can use all different passwords for each service without the burden of remembering them.
Registering a password:
Be advised1. Tap the Home tab > Settings.
2. Tap Account.
Note: Tap here to go to the Account screen from your smartphone.
3. Tap Password.
4. Enter a password.
Note:
- 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, lower case letters, numbers, and symbols.
- Be sure to write your new password down so you don’t forget it.
Checking/changing your password:
There is no way to check the string of characters you registered as your password. If you don't know or have forgotten your password, please change it.
Note: Once you've changed your password, be sure to write your new one down so you don't forget it.
If you still have the device you can use LINE on
To change your password:1. Tap the Home tab > Settings > Account.
Note: Tap here to go to the Account screen from your smartphone.
2. Tap Password.
Note: If you're asked to unlock the screen, use the unlock method you have configured on your device, such as your passcode or biometrics (e.g. fingerprint, face). Do not use the password registered to your LINE account.
3. Enter your new password twice, then tap Change password.
Note: 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, lower case letters, numbers, and symbols.
