• Creat a Strong password : you should creat a memorable password which should be 8 characters in lenght, or more. Add numbers and symboles to your words and phrases to make your password hard for others to guess, for example "IL0ve@Skyr0k*1312"
Ps : Never make simple words that are easy to guess as your name, your birth date, your login name, or weak password like "1234" "azerty" etc, you also have to avoid dictionary words in any language cos "Criminals use sophisticated tools that can rapidly guess passwords that are based on words in multiple dictionaries {source, microsoft}"
and for more security, don't store your password online to not let malicious find it and acces your acount ;)
• Never Share your password with others : Sharing your password gives others acces to your acount and your informations, and you lose control over how your acount is used, though you are still responsible for anything done in your name.
• Don't allow Softwares to save your passwords for you : Anyone who use your computer could acces to you passwords.
• Never provide your password over e-mail or based on an e-mail request : Beware of anyone claiming to need your password; no system administrator will ever ask you for your password.
"Internet "phishing" scams use fraudulent e-mail messages to entice you into revealing your user names and passwords, steal your identity, and more. Learn more about phishing scams and how to deal with online fraud {source, microsoft}"
• Change your password : In case you feel that someone using your acount, you have to change your password immediatley.
• Do not type passwords on computers that you do not control : Computers such as those in Internet cafés, Friend's computer...
• Protect your computer with a strong Anti-Virus and Firewall : Kaspersky, Zone Alarm are good enough to protect your informations ;)
