On Facebook, we have important friends, business connections, fans. We have a lots of personal details, chats, photographs available there. We are connected with many important groups and pages, for some group/pages, we are active members while for others, we have admin rights and strong reputation there.
We have authenticated various apps of other services with our Facebook account and there are many other stuff that concern us, related to our Facebook account. These things make our Facebook account one of the most important accounts online.
Not just we but Facebook staff members are also very sensitive about their all user’s Facebook account security. So, they spend a lot of money, hardwork and strategies to make user’s Facebook account more and more secure but still hackers always find a way and, hacks happen.
If your Facebook account has been hacked then it is very important to recover it as soon as possible to minimize the damage to your account that the hacked can deliver.
So, here are some effective tips to get your Facebook account back: 

1. Submit Report to Facebook

The first and foremost task is to report Facebook team about the hacking of your Facebook account so that they can take immediate steps to protect it. Follow following steps:
  1. Go to the Facebook Account Compromise Reporting Page
  2. Click the “My Account is Compromised” button
  3. On “Find Your Account” page, you need to identify yourself. At the provided box, enter your email, registered phone number, user name or full name. Now, click the “Search” button.
  4. Follow the instructions provided to report your account as compromised.
  5.  Now, after following the recovery steps, you will be able to gain access of your account back. You might have got verification/password-reset link via email, verification code via SMS on phone that helped you to reset your Facebook password again.
  6. If the verification code/link just provided you the access of your account, it is recommended to change your Facebook password immediately. You can do this by visiting your “Account Settings” page and clicking “Change” link under “My Account” Password section.
  7. Now visit Facebook Privacy Settings page, click on “Apps and Website” and delete all the suspicious apps that hacker have used to hack your account by clicking “Edit Settings” and then “X” under “Apps You Use” section
  8. Check your activity log to know locate any suspecious activity done by the hacker using your account for example commenting, status updates, post on friend’s timeline etc.
  9. Inform your friends and followers that your account was hacked and if someone sent them any message or suspicious links then don’t click those links.

If your personal information has been changed.

Many hackers change the personal information inside the victim’s Facebook account such as Friends removal, password, email change, images/albums delete etc. It makes recovering Facebook account much more difficult for victim as the easiest and quick option (the above step) will become useless. In that case, you can try these steps:

2. Ask Friends To Report Your Account as Hacked

You can contact your Facebook friends by phone calls and through other ways like by email or other social networks and request them to “report your Facebook account” suspicious either through the more (…) option at your Facebook timeline or by clicking down-arrow at any post updates done by your hacked Facebook account.
The reporting procedure is somewhat slow and one-two reports are normally ignored by the team but if more people report your account suspicious, Facebook will take it the issue seriously.
