My first guide with Facebook. I'm going to show you guys how to see who logged into your Facebook. This guide was made on an iPod so it might be different on the PC.
1. Open up the little side menu, just click on the three lines in the top left corner usually.
2. Navigate to Account Settings, then select Security.
3. Check Text Message Login Notifications and Email Login notifications.
Boom now you can see who logged in to your Facebook through text message and email.
