This tutorial is for changing your current password. If you've forgotten your current password, follow the steps in the Heavy tutorial below:
1. Login to Facebook Using Your Current Password
Once logged in, go to the top right of your page and click on the settings icon.
2. Go to Your "Settings" Page
Click on the "Settings" option.
Clicking on "settings" will navigate you to your account settings page. Look for the "Password" area four options down. Click the "Edit" button on the right.
3. Change Your Password
After clicking on the Edit option, you have to enter in your current password, then create your new one. Make sure the new password you make is either "medium" or "strong". Having a weak password makes it easier for your Facebook to be compromised again in the future.
When you're done, click on "Save Changes."
