How do you change your Facebook password?
You can try a few other approaches. The simplest option is to utilize a recovery code, but you'll need access to the email account you used to sign up for Facebook:
To begin, go to the Facebook login page.
Try logging in with the most recent password you recall.
Google will send a recovery code to the email address connected with your account if it is invalid. You can use it to access your account.
What should you do if the email address you used to sign up is no longer valid? You can still recover your Facebook account through a backup email address or phone number. It will also work if you’ve linked Facebook with your Google account.
