Step 1. Enable Two Factor Authentication via an anonymous Security App.
Enabling two factor authentication (2FA) is one of the best ways to secure your account. Facebook provides two methods.
- SMS via your phone – requires service
- App based codes via your phone (or tablet) – this does not require an active data connection
If you’re not a fan of Facebook knowing your phone number and don’t want to enable two factor authentication using that method, then you’re in luck! Simply go to the two factor settings page and select “add an app”.
You can download the Google Authentication application to your phone and enable it using the steps provided on Facebook’s page. This code generator is 100% anonymous and based on an open standard called “Time-based One Time Password” algorithm.
Once enabled, anyone who attempts to login with your account with a correct password will be required to enter a generated number. This number changes every 30 seconds. Facebook will generally ask you to use the 2FA code when you attempt to sign in to an unknown computer or device.
Step 2. Remove Those Old Apps
If you’ve ever been a “victim” of spam posts, it’s likely an old rogue app posting on your behalf and tagging your friends.
You’ve probably added a lot of apps in your life time. Some may be dead, and some may be harvesting your data as you sleep. Head on over to the applications and websites settings and you’ll be able to see them all.
Just review and edit ones you think you no longer use. You can remove them outright by checking the box and clicking “Remove.”
You can also use this to report bad apps that you may have.
Hopefully this helps you out.
