You can’t restore a deleted Facebook account. After nearly 90 days, all of your Facebook data will be permanently wiped. You won’t be able to access any of the other applications you’ve connected your Facebook account to.
Even after you delete your account, Facebook will keep it alive for 30 days in the hopes that you will reconsider. When the deletion is finished, all that should be left of your account 90 days later is activity records kept by Facebook for its own purposes.
What happens if I permanently delete my Facebook account? Your profile, photographs, comments, films, and everything else you’ve added will be permanently erased. You won’t be able to recover anything you’ve posted. Facebook Messenger will no longer be accessible to you.
You can reactivate your Facebook account at any time by logging back into Facebook or by using your Facebook account to log in somewhere else. Remember that you’ll need to have access to the email or mobile number you use to log in. If you can’t remember your password, you can request a new one.
If you deactivate your account, Facebook keeps all of your data for you to quickly reactivate it if you change your mind and want to use the social network again. After a certain period of time, Facebook does not remove past account information, so you may reopen Facebook a year later.
