Shops that answer customers on LINE OA all day type faster and see more on a computer than on a phone. LINE Official Account Manager has a web version you can use on a computer. This article sums up, from LINE's help center, how to open it, turn on chat, set notifications and add your team, and the limits worth knowing.

What is LINE Official Account Manager?

LINE Official Account Manager is LINE's place to manage a LINE OA: answer chats, send broadcasts, set the rich menu and see the account's numbers. It comes as a phone app and as a web version you open on a computer. No account yet? Read how to sign up for LINE OA first, and if you are not sure what a LINE OA is, see what a LINE OA is.

What you need to use LINE OA on a computer

A computer running Windows or Mac
The latest Chrome with JavaScript on (Internet Explorer is not supported)
A LINE account with an email address registered, or a business account made with an email address
A phone with the LINE app, to confirm it is you when you log in with a LINE account

How to open LINE Official Account Manager on a computer

Open Chrome and go to manager.line.biz
Choose to log in with a LINE account or with a business account, then enter the email address and password
If you log in with a LINE account, the computer shows a 4-digit code; enter it in the LINE app on your phone (not the LINE Official Account app)
Pick the LINE OA you want to manage; one Business ID can hold up to 100 accounts

Forgot the password of a business account? Choose to reset it where you log in, then follow the email LINE sends you.

Turn on chat and answer customers on a computer

Chat in a LINE OA has to be turned on first. Go to Settings, then Response settings, and turn on Chat. After that you answer customers from the Chats tab and can send pictures and files (LINE does not scan files for viruses, so do not open a file you are unsure of).

Notifications when you use the computer and the phone together

Notifications are set in the LINE Official Account app only. If the web version on your computer and the app on your phone use the same Business ID, the app may not tell you about new chats. Turn on new messages while using the web version in the chat notification settings.

Add your team so they can help answer

The account owner adds people from Manage permissions in Settings: choose a permission type, create a link and send it to the person. They open the link, log in with their own account and accept the role, so everyone answers from their own computer without sharing one password.

Chat limits in LINE OA worth knowing

Chat history is kept free for 6 months; with the OA chat package it is kept for 5 years
Free: 5 tags, 1 tag per chat and 1 note per chat
OA chat package: 300 tags, up to 30 tags per chat and up to 1,000 notes per chat
Each account opens on its own; a shop with several LINE OA accounts switches accounts to see each one's chats

Source: LINE Official Account help centre, login and chat sections (Thai): chat history retention, tags and notes; supported computers, the login code and adding your team from the English help centre (checked 28 October 2026). Menus and limits may change when LINE announces them.

When chat inbox software makes more sense

LINE Official Account Manager is enough for a shop with one account and a few people answering. If the shop has several LINE OA accounts, several people answering, or wants more tags and customer notes, chat inbox software helps. See how to choose chat inbox software.

Summary

Use LINE OA on a computer at manager.line.biz in Chrome on Windows or Mac.
