The Facebook Security team sent the following guidelines to help keep Facebook Account secure in future:
1. Password Protection: Use a complex string of numbers, letters, and punctuation marks that is at least six characters in length and unique and complex password for your Facebook Account and keep this completely to yourself. Use the password which should also be different from other password you use elsewhere on internet.
2. Private Browsing: When you’re done with facebook site please make sure that you log out of your Facebook Account and quit browser. Especially important when you use a public computer network and never check the “Remember Me” box when you logging in from a public computer, as this will keep you logged in even after you close your browser window.
3. Secure Email: You should use different password for you Facebook Account and email account which is associated. If anyone can read your email can probably also access your Facebook Account so secure it. By changing your passwords, you can to a great extent decrease your account’s risk of being compromised in the future.
4. Security Question: Add a security question to you account from the account setting page if you have not done so already. Please note if you don’t see the option for a security question that means there is already a question and answer associated with that account.
5. Log in at Facebook.com: Don’t use any other page for log in related to facebook.com when you access the site, you always log in from genuine Facebook page with the facebook.com domain. If something looks or feels doubtful, go directly to www.facebook.com to log in
