Free Password Strength Meter

Free Password Strength Meter is an app that helps you find out the strength of your passwords. An algorithm that can assess the resistance of your password to brute-force attacks takes care of this. Just enter your chosen password in a special field and the app will show you the strength level. It uses information entropy as a measure of strength and reliability. Entropy measures the number of bits of entropy in passwords. Each bit doubles the strength of the password.
