Username is unique Facebook identity, that you may find in your profile URL. Example : https://www.facebook.com/zuck. Here zuck is the username of Mark Zuckerberg.
You should see your profile with recovery email address and mobile number if any. Select mobile number or email address that you can access right now and then click Continue.
Check your mailbox if you choose email / mobile inbox if you choose mobile number to get the recovery code. Enter the recovery code to continue.
That’s all. Set your new password and get back to your Facebook account.
2. Password Changed & No Access to Associated Email:
Enter your email or mobile number or username or name in the textbox and click search.
Click “No longer have access to these?” at the bottom of the reset password dialog box.
You will be directed to extended recovery options. It may vary for different Facebook accounts
Security Question : This option is unavailable for new Facebook accounts but old Facebook users can make use of it. You can answer this question to proceed to set new password if it is listed as one of the extended recovery options.
Trusted Contacts : You can use this option only if you have already choosen trusted contacts.
Enter a new email address or phone that you know you can access and click Continue.
Click Reveal My Trusted Contacts and type the full name of one of your trusted contacts.
You’ll see a set of instructions that includes a URL. The URL contains a special security code that only your trusted contacts can access. Call your friends and give them the URL so that they can open the link and give the security code to you.
Use the security codes from your trusted contacts to access your account.
3. Password & Associated Email Address Changed
Here the hacker changed your password as well as your associated email address. This case is somewhat hard to recover since the hacker blocked a way to recover. We have two options in this case. You should either have access to mobile number or old email address.
