Facebook knows a lot about you but the social media company is not alone here. Many third-party apps and websites are also a part of this. A new report suggests that about 90 million Facebook accounts have been affected by a vulnerability that was recently discovered by the Facebook engineers in one of the features of the app.

Sadly, this is not the first such report. There is a new story almost every day raising questions on Facebook and its user data security features.

In such a time it has become difficult as well as crucial to protect your personal data that you share on Facebook. Here are few steps you can take to safeguard your Facebook and keep it private:

1. Keep a tab of your apps: This is the first thing you do after you are done reading this. Go to Facebook and unlink all your apps from your the social media app.

To see the list of apps that have access to your Facebook and to delete them, go to Settings > Apps and websites. You will see a list of apps and websites that you’ve used Facebook to log into. They can request info you chose to share with them. Remove the apps and websites that you no longer want.

2. Say no to the quizzes: Cambridge Analytica had created its own quizzes to harvest data from Facebook. You may end up sharing more information than you think you are giving to these third-party data collectors. So avoid taking weird quizzes on Facebook.

3. Photo privacy settings: Facebook by default keeps all your posts public. Make sure that you have specified your audience before you post anything especially your photos. It is better to select “Only friends” as your post’s viewer.

4. Login notifications: Enable the login alerts from Settings o receive notifications every time your account is logged in from an unknown computer or phone. To activate it, go to Security and Login Settings> Settings> Get alerts about unrecognized logins and click edit> Choose where you want to receive alerts> Save changes.

5. Remove location information: When you post something, Facebook sometimes automatically picks up your location. It is not a great idea to inform everyone about your location. So keep an eye and if possible always try to remove the location details from your post.

6. Block suspicious friends: If you see friend behaving weird on Facebook or posting absurd things, chances are his account could be hacked. Call him or her to confirm first and if yes then block that friend on Facebook as soon as possible.

7. Keep your personal details private: Your private details like your number of Facebook friends, your age or your residing city should not be disclosed to all. It is better you keep them private.
