How to Stop All Friend Requests on Facebook

On Mobile

Open Facebook. It's a dark-blue app with a white "f" on it. Doing so will open your News Feed if you're logged into Facebook. If you aren't logged in, first enter your email address (or phone number) and password.

Tap ☰. It's either in the bottom-right corner of the screen (iPhone) or in the top-right corner of the screen (Android).

Scroll down and tap Settings. You'll find this option toward the bottom of the menu. Skip this step for Android.

Tap Account Settings. It's either at the top of a pop-up menu (iPhone) or toward the bottom of the ☰ menu (Android).

Tap Privacy. This tab is near the top of the screen.

Tap Who can send you friend requests?. This option is near the bottom of the screen.

Tap Friends of friends. It's the second option near the top of the page. Doing so will prevent anyone who doesn't belong to any of your friends' friend lists from randomly adding you on Facebook.

On Your Computer

Go to Facebook's website. It's at https://www.facebook.com/. If you're already logged into Facebook, doing so will open your News Feed. If you aren't logged into Facebook, you'll first enter your email address (or phone number) and password in the upper-right side of the page.

Click ▼. It's in the top-right side of the Facebook window.

Click Settings. This option is near the bottom of the drop-down menu.

Click Privacy. It's a tab on the left side of the page.

Click Edit to the right of "Who can contact me?". This section is about halfway down the page.

Click Everyone. This box is below the "Who can send you friend requests?" heading.

Click Friends of friends. It's an option in the box's drop-down menu. Doing so will set your Facebook friend requests setting to "Friends of friends", which will prevent people not in your friend group from friending you.
