Having someone hack into your Facebook account will not only make your own life miserable but it could severely affect your business if your account has administrative access to your Facebook business page. Changing your Facebook password only takes a few seconds, so it’s a good idea to change it whenever you suspect someone may have accessed your computer, or routinely every few months. If you find viruses or malware on your computer, change your Facebook password. If others have administrative access to your business page, remind them to keep their passwords secure as well.
1 Log in to Facebook and click the gear icon in the top right corner of any Facebook page. Select “Account Settings” from the drop-down menu. The General Account Settings page opens.
2 Click “Edit” link on the right side of the Password section.
3 Type your current password in the “Current” text field. Type your new password in the “New” and “Re-type New” fields. Click the “Save Changes” button
