Free Password Strength Meter is a small utility designed simply for checking the strength of a specific password by using several known measures to verify the overall password strength and security before you actually put it to use.
By using this utility you will always be sure that your passwords can resist attempts to crack them via guessing or brute-force attacks ahead of time.
Free Password Strength Meter is very easy to use - you just need to enter your chosen password, and the application will show the strength level by using information entropy as a measure of strength and reliability.
Entropy measures the number of entropy bits in passwords. For example, if your password entropy has 53 bits of strength, it means that your password is as secure as a string that consists of 53 bits chosen by fair coin toss. Each bit of entropy makes your password twice as strong.
