How do I Change a Facebook Password?by Lara Webster ; Updated September 15, 2017
Protecting your Facebook page with a strong password is an important step in maintaining privacy on the site. If someone gains access to your account, he can change information on your profile or send out messages in your name. Facebook requires that all passwords be at least six characters long and recommends that a password contain both numbers and letters. If you think your password has been compromised, or you forgot to log out of another person's computer, change it in a few easy steps.
Log into Facebook and click on the "Account" link, which is located in the upper right-hand corner of any Facebook page.
Select "Account Settings" from the "Account" drop-down menu.
Click on the "Settings" tab. Locate the "Password" section of the page and click the blue "Change" link.
Enter your old password to confirm your identity. Type your new password twice, once in the "New Password" field and once in the "Confirm Password" field.
Click "Change Password."
When you change your password, you will be logged out of Facebook on other computers where you are currently logged in.
