 To find out if an unknown person has logged into your Facebook account

At first you need to log in from a desktop browser. Now open Settings and select Security and Logins. Then click on the Where you’re logged in option. Now you will see your latest login in succession. Also, Facebook will tell you where you have logged in and from which device you have logged in. You can log-out individually from each device. If you want, you can log out of all your devices by selecting Log out of all sessions.

Send confidential emails to Gmail this easy way, even the crows won't notice! How do you prevent others from signing in to your Facebook account? Enable two-factor authentication to make your Facebook account more secure. To enable two-factor authentication, open Settings and select Security and login.

Now select Use two-factor authentication and click on Edit option. You can secure the account via OTP to the phone number each time you log in if you wish. Also, code can be generated using apps like Authy or Google Authenticator. You must enter this code each time you log in.
