Can Facebook or any Social Networking site be Hacked? Confusion!

A Social Networking Site is secured by Social Guardian. All the social networking sites uses passwords, username, email, phone number, etc. And most of the Social Networking site is hacked by Phishing by taking the requirement for log in to the person's account and the information could be anything be it email, password, username, etc.
Username:- example123
Password:- password@123

And by this information a attacker can gain access to your social media account.

We cannot call it CRACKING because in cracking we can recover the password using md5 code or hash code and if we get the hash code than its impossible to decrypt the hash code or md5 code.

Steps to protect your account from being hacked:-

1. Create a Strong Password with modulars, numbers, alphabets eg:- paSsworD@123
2. Change password once in a month
3. If somehow a person came to know your password than change it immediately
4. Don't give you password and username to anyone
5. In pc use Virtual Keyboard to input passwords and usernames
6. Don't save any password in browser
