If you are on a Windows, Mac, Linux, or Chromebook computer, use the Facebook website to lock your profile. To do so, first, open a web browser on your computer and launch the Facebook site. If you have not already, log in to your account on the site.

In Facebook’s top-right corner, click your profile picture and then click your name.

On the profile page, in the tabs row beneath your name, click the three dots (which are to the extreme right of the tab list).

From the menu that appears, select “Lock Profile”

You will see a “Lock Your Profile” window. Here, click “Lock Your Profile”

And your Facebook profile is now locked. Close the lock profile window by clicking “OK”

You’re all set. Only certain parts of your profile are now visible to the public. If you ever want to unlock your profile, then click the three-dots menu > Unlock Profile > Unlock > Unlock Your Profile.

Lock your Facebook Profile on Mobile

If you use an iPhone, iPad, or Android phone, start by launching the Facebook app on your phone. In the app, tap the three horizontal lines. If you are on an iPhone or iPad, you will see these lines in the bottom-right corner of the app. If you are on Android, these lines are at the top-right corner. On the “Menu” screen that opens, tap your profile at the top.

• On the profile page, beneath your name, tap the three dots. You will see a “Profile Settings” page. Here, tap “Lock Profile.”
• On the “Lock Your Profile” screen, tap “Lock Your Profile.” Facebook will display the success message. And you have successfully locked your profile from non-friends on Facebook.
• To unlock your profile, simply tap “Unlock Profile” where you tapped “Lock Profile” in the above steps and choose Unlock > Unlock Your Profile.

And that’s how you ensure the people who aren’t your Facebook friends only see limited information about you. Stay private!
