What is password strength?
According to WikiPedia:
Password
strength is a measurement of the effectiveness of a password as an
authentication credential. Specifically, it estimates how many trials an
attacker who does not have direct access to the password would need, on
average, to correctly guess it. The strength of a password is a
function of length, complexity, and randomness.
How to create a Strong Password?
We all know the common guidelines for choosing a strong password:- Include numbers, symbols, upper and lowercase letters
- Password should be more than 8 characters long.
- Avoid any password based on repetition, dictionary words, letter or number sequences, usernames, relative or pet names, or biographical information (birth day).
The Password Phrase method
The phrase method is an easy way to remember complicated passwords that are hard to crack.- Use the Phrase Method:
- Choose a phrase that has numbers.
- Use only the first letter in each word.
- Use the proper case for each letter, just as it appears in the phrase.
- Use actual numbers whenever possible. Use “2″ for “two” or “to” and “4″ for “four” or “for.”
- Include punctuation.
My flight to New York will leave at three in the afternoon!
Using the Password Phrase method explained above, the password becomes:
MftNYwla3ita!
Don’t remember the password, just remember the phrase.You can see that this Password abides by the Strong Password Creation rule and it is also easy to remember!
You can even use a phrase as the password if the system allows you to enter a phrase. For example the following phrase will make a strong password.
I prefer to go to bed by 10:00!
