Often there are surely only one thing standing between your sense of information and criminals, your password.If they get it, they can get into your bank accounts and private files and re*.For this reason, it is important to know what makes a password strong and secure.These  secure passwords explained by common craft.Chances are you use passwords everyday to open your computer,log on your favorite websites to get work down.The easy route is to have a simple password that works everywhere,unfortunately this can be a problem.Criminals are very good at guessing passwords. Some have computer programs that can make millions of guesses until something works.And if they already know information about you, it is even easier. Your job is to create a password that is very hard to guess.Here is how.Your first thought may be to use a pet's name,a birth date,and  address or part of the  phone number,these things are too easy for criminals to discover.So don't use them.Your password should not include information about you.Thankfully, there are  ways that are memorable but hard to guess passwords.Consider this, in addition to single words , phrases can also be easy to remember. Maybe it is a favourite song lyric or quote. An example of this is Jack and Joan went up the hill, that is easy to remember, right?Well, your password is there,it is the first letter of each word, and this is the example , this will be your password.That is something that is not easily guessed. Here is why.First, it is not in the dictionary. This makes guessing harder. There are about 60,000 words in English, a computer can test up those words very quickly,so don't use them.But there are more. This password can still be stronger by adding a* letters, numbers or special characters.Now this is a strong password, but there is still risk.If you write it down, be careful where you keep it .Be aware that somebody can look over your shoulder or find it in your trash.Giving it a loved one is also risky.They may not be as cautious as you are,only you should know your password.Criminal may also try to fool you into handing it over via phone calls.Never tell anyone your password over the phone.And be careful when you get an email that asks for a password. It could be a scam.To help avoid problems, don't use the same password everywhere,that's like using one key that locks everything you own. The stakes are high if you lose it.Also, be careful if you use a computer that is not yours.Let's say you check email using a computer in the store,library or computer lab.You log in,check email and walk away.  The next person to use that computer now has access to your email account and all the information in it. Always remember to log out of each site you visist on the computer that isn't yours. Passwords are  the central part of life online, and if you are not careful about keeping them  secret ,they can cause big problems.By understanding the risks, and making passwords stronger, we can feel a little more secure.
