If you’ve ever deleted Facebook from your device, you know how frustrating it can be to have to reinstall the app and then find that all your data is gone. If you’re like most people, you probably don’t even know how to reactivate a deleted Facebook app. Here’s how:

  1. Open the Facebook app on your device and sign in.
  2. Click on the three lines in the top left corner of the main screen and select “Activate account.”
  3. Enter your email address and password if they’re different from those used when you first logged in to Facebook. If everything looks good, click on “Activate account.” If not, check for updates and make sure there are no problems with your account before clicking on “Activate account.”
