To change your Facebook password from a computer, open Facebook in a web browser and log in to your account. Click the downward-pointing arrow icon in the top-right corner of the page, then select "Settings & privacy" followed by "Settings." In the left sidebar, click "Password," then click the "Change" button next to the password field. Enter your current password, then type your new password twice to confirm it. Click "Save changes" to complete the process.
Your new password should be at least 6 characters long and unique from your previous passwords. For security, use a combination of uppercase and lowercase letters, numbers, and symbols. Avoid using personal information like your name or birth date. After changing your password, you'll be logged out of your account and will need to log back in with your new credentials. If you've forgotten your current password, click the "Forgot password?" link on the login page and follow the account recovery steps using your email address or phone number associated with your Facebook account.
