Once you've signed out of your account, go to the Settings menu. In the left sidebar, click on Security and Login. You should then see a list of all the devices that are currently logged in. To remove a device from this list, click on the "See More" option. You can then select "Log out" from the drop-down menu that appears.
Open the app and tap the More button. It looks like three horizontal lines aligned vertically. Choose Account Settings and Security. In the Security and Login tab, find the Where you're logged in section. You will see your Messenger login information under this section. Click the 'Log Out' button to confirm your action. Repeat the steps above to logout of your Facebook Messenger app.
Go to the Settings menu of the Facebook app and tap the Log Out option. Then, tap the icon next to the message you want to end. Then, tap the "X" to log out. This will log you out of the entire Messenger session. This method is best suited for logging out from the app, where you don't want other people to see your messages.
If the above method doesn't work, try clearing the cache or data from the app. This will remove any data from Messenger and your Facebook account. Finally, if all else fails, switch to a different account to prevent any further trouble. The more you use the app, the less likely it is to be hacked. That way, you'll never get a chance to get hacked or exposed by anyone.
First, open the app and go to the settings. In iOS, go to the settings. Scroll down to the Security & Login section. Tap the three-dot menu next to the app. In the Messenger settings, tap the "Cache" option. Afterwards, you should logout from the messaging service. The next step is to delete your cache. However, you don't need to uninstall the app.
Open the Facebook app. Go to Settings. Then, select Security and Privacy. You can now logout from the app. Then, you'll be prompted to sign in again. If you're using the same device, you can even log in again by using the same password and PIN. There are two ways to logout from Facebook Messenger. The first method is to close the app, while the second is to close it.
The second method involves deleting the data from your Facebook messenger app. Then, sign in to the main Facebook app. This will remove all the data from the Messenger application. Once you've signed out of the apps, you'll be able to log out of the Facebook messenger service. You can also sign in by using your passwords. If you've already signed in to your account, make sure you've unlocked the login screen.
