Weak password is important in today's network security threats. Many users use easily guessed passwords or very simple digital common passwords. Important reasons for this password is easy to crack or guess, this is the attacker to many network devices or website account.
Recommended to change strong passwords is a very common thing, no matter how many security agencies recommended that some users are still reluctant to use strong passwords, because it is not easy to remember. Therefore, FBI recently released a new recommendation :. "Instead of using complex passwords short and difficult to remember, it is better to consider using a longer password phrase that involve long strings multiple words combined into at least 15 characters. the extra length of the password phrase to make it more difficult to crack, but also to make it easier for you to remember. "
Simple and easy to crack password guessing is basically insecure, but it takes time to crack, hackers guess it depends only on luck or dictionary is strong enough. However, each password length will cause an increase in the time required for a hacker to crack double. Also, if you want to direct guess, will increase the difficulty. Therefore, the new FBI is recommended, if you really do not want to use complex passwords, it is best to your simple password to add a few, in order to improve security. For example, many users are using a password 123456 or password. If you can add other numbers after 123456, you can increase password strength.
Of course, if you can, and then add the letter or punctuation mark before pure digital password, the password strength will be significantly increased, so that hackers crack passwords longer time.
Although this type of password is still not strong enough, but it is much more than pure digital password security, so if you really do not want to use complex passwords, that is enough.
