How to Recover Your Facebook Account When You Can't Log In
Are you having trouble logging into Facebook? Whether you’ve forgotten your login details or your Facebook account has been hacked, there’s no need to panic. There are a few different ways to recover a Facebook account if you can’t log in.
If you think your account has been hacked, you should probably review Facebook's top privacy tips and make sure it doesn't happen again. But if for some reason you can't remember your login details, the simple recovery process should help you get back into Facebook.
It may sound crazy, but if you find yourself logged out of your account, the first thing you should do is check if you still have an active Facebook session on one of your devices. For example, if you can’t log into Facebook on your smartphone, it’s possible that you’re still logged in on your desktop, and vice versa.
