You Need to Sign Out of LINE and Can’t Find the Option
It happens to the best of us. You’re lending your phone to a friend, selling an old tablet, or simply want to switch LINE accounts on your device. You open the app, tap around frantically, and realize the logout button is nowhere to be found. Unlike most social apps where signing out is a straightforward affair, LINE buries this function for a very specific reason tied to its core design.
This guide cuts through the confusion. Whether you’re on an iPhone, Android, a computer, or even a locked device, we’ll walk you through the exact steps to safely log out of the LINE app. We’ll also explain the critical difference between simply closing the app and properly signing out, and what you must do beforehand to avoid losing your precious chats and stickers forever.
Why LINE Makes Logging Out So Deliberate
Before we dive into the steps, understanding LINE’s philosophy is key. LINE is designed first and foremost as a persistent, mobile-centric messaging platform. Your account is tightly bound to the device you use to register it. The “Log Out” function isn’t meant for daily use; it’s a nuclear option for transferring your account to a new phone or removing it entirely from a device.
When you log out, you are effectively disconnecting your LINE account from that specific device. If you have not taken the essential precaution of linking your account to an email and password or Facebook, logging out can mean permanent data loss. The app hides this powerful function to prevent accidental taps that could lead to a support nightmare.
The Crucial Pre-Logout Checklist
Never attempt to log out of LINE without completing these steps first. Treat this as a mandatory safety protocol.
– Ensure your account is backed up and transfer-ready. Go to Settings > Account > LINE Account and verify it is linked to an email address and password or a Facebook account. This is your lifeline.
– If you care about your chat history, manually back up your chats. On iOS, use iCloud backup within LINE’s settings. On Android, use the built-in Google Drive backup feature (Settings > Chats > Chat history backup). Remember, backing up to your device’s local storage does not help when you log out.
– Know your password. If you’ve only ever logged in with a phone number and SMS verification, you must set up an email/password combination in the Account settings before proceeding.
How to Log Out of LINE on iPhone and iPad
The process on iOS is uniform, though the path involves several menus. Follow these steps precisely.
First, open the LINE app and tap on the “More” tab (the three dots icon) at the bottom right. Next, tap the gear icon in the top right corner to enter Settings. Here, you will see your account profile at the top.
Tap on your account name or profile picture to enter the “Account” settings menu. Scroll down this list. You will see options like “LINE Account,” “Privacy,” and “Safety.” Continue scrolling until you find the option labeled “Delete account.” Do not be alarmed.
Tap on “Delete account.” On the next screen, LINE will present you with several options and warnings. Among these, you will finally see the button you’ve been looking for: “Log out.” Tap it.
The app will ask for final confirmation, warning you that you will be logged out on this device. Confirm your choice. The app will close and return you to the initial login screen. Your account is now successfully signed out on that iPhone or iPad.
How to Log Out of LINE on Android Phones and Tablets
The Android procedure is very similar to iOS, with minor visual differences depending on your device’s manufacturer. Start by opening LINE and tapping on the “More” tab (three lines or dots) usually found at the top-right or bottom-right.
Select “Settings” from this menu. Within Settings, tap on “Account.” This is the central hub for your profile and security. Scroll carefully through the Account settings list.
Look for the entry titled “Delete account” or “Deactivate account.” Tap on it. On the subsequent warning screen, you will be presented with the option to “Log out.” Select it.
Confirm the logout when prompted. The app will exit and return to the welcome screen, indicating you have been fully logged out of your LINE account on that Android device.
What If the “Delete Account” Option Is Missing?
Some Android variants or older LINE versions may have a slightly different flow. If you cannot find “Delete account,” look for a menu option called “Security and privacy” or simply “Privacy” within Settings. The logout function is sometimes housed there as a safety feature.
As a universal fallback, you can try accessing the logout function via the in-app “Settings” search bar. Type “logout” or “sign out” to see if the app directs you to the correct menu.
Logging Out of LINE on a Windows or Mac Computer
The process for the desktop version of LINE is significantly more straightforward, as the desktop app is treated as a secondary, linked device. Open the LINE application on your Windows PC or Mac.
Click on your profile picture or name in the bottom left corner of the sidebar to open the menu. From this menu, select “Settings.” Alternatively, you can often find a gear icon near your profile.
In the Settings window, navigate to the “Account” tab. Here, you will see a large, prominent button that says “Log out.” Click it.
Confirm the action in the pop-up dialog. The desktop app will immediately close all chats and return to the QR code login screen. You are now logged out. Remember, logging out on desktop does not affect your mobile device login.
The Nuclear Option: When You Can’t Access the App at All
Perhaps you’ve sold a phone without logging out, lost a device, or are locked out and need to remotely terminate the session. LINE provides official, legal methods for this scenario.
Your first and best tool is the “LINE Account” management page accessed via a web browser. Go to the LINE website and find the account login page. Log in using the email and password linked to your account (this is why that pre-checklist is vital).
Once inside your account management console, look for a section named “Logged-in devices,” “Connected devices,” or “Security.” Here, you will see a list of all devices where your LINE account is currently active. You can select any device and choose “Remove” or “Log out from this device.” This will remotely terminate the session, forcing a logout on the target phone, tablet, or computer.
Using Find My Device for Android or iCloud for iPhone
If you have lost the physical device and need to secure your data, you can use your platform’s device-finding service to perform a remote factory reset. This is a last resort, as it erases the entire device.
For Android, use Google’s Find My Device service from another browser. Select the lost device and choose “Erase device.” This will wipe the phone, including the LINE app and its local data, effectively logging you out.
For iPhone and iPad, use iCloud’s Find My service. Select the device and use the “Erase iPhone” option. This performs a complete remote factory reset, removing all apps and data. After such an erase, you must use your LINE email/password to log in again on a new device.
Common Mistakes and Troubleshooting After Logout
Even after a successful logout, users often run into a few predictable issues. Let’s solve them proactively.
The most common panic is seeing the “This account is being used on another device” error when trying to log back in. This simply means your account session is still active somewhere. Use the web-based “LINE Account” method described above to remotely log out from all devices, then try logging in again on your preferred device.
Another frequent problem is losing all chat history after logging out and back in. This occurs because you relied on local device storage instead of a cloud backup. Unfortunately, local chat history is tied to the device installation. Once you log out, that local data is often cleared. The only recovery is if you had previously enabled and performed a successful iCloud or Google Drive backup.
What if you forgot the password for your LINE account? On the login screen, use the “Forgot password?” link. LINE will send a reset link to the email address associated with your account. If you never set up an email, your only recourse is to contact LINE support directly, which can be a lengthy process requiring proof of ownership.
Your Strategic Next Steps for LINE Account Management
Now that you’ve mastered the logout process, turn this knowledge into a robust account management strategy. First, immediately link your LINE account to both an email and a Facebook account. This creates multiple recovery paths. Second, set a calendar reminder to perform a manual chat backup to the cloud once a month, especially if you have important conversations.
Treat your LINE login like your house keys. You wouldn’t leave copies lying around. Use the remote device management page periodically to audit which devices are connected to your account and remove any you no longer use or recognize. This simple habit greatly enhances your account security.
Logging out of LINE is a powerful administrative action, not a casual one. By following the precise steps for your device and always prioritizing backup first, you can switch devices, secure your data, and maintain control over your messaging life with complete confidence.
