Often there are surely only one thing standing between your sensitive information and criminals, your password.If they get it, they can get into the bank accounts and private files and  wreak havoc. For this reason, it is important to know what makes a password strong and secure.These is 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,an address or part of the telephone 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 always to have 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's easy to remember, right?Well, your password is there,it is the first letter of each word, in this example , this will be your password.That's not something is easily guessed. Here is why.First, it is not in the dictionary. This makes guessing it harder. There are about 60,000 words in English, a computer can test up those words pretty quickly,so don't use them.But there's more. This password can still be stronger by adding upper-case letters, numbers or special characters.So now this is a very strong password, but there is still a 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 to a loved one is also risky.They may not be as cautious as you are,only you should know your password.Criminals 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 having 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, likes 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.
