PasswordMeter.com - Test Your Password Strength

The Password Meter is a free program that will assess the general strength of any password you enter, so you can get an idea of how secure your password really is. There is no registration necessary to use The Password Meter. The interface is very intuitive, so from the homepage you immediately know to key in the password you’re testing (which must meet some minimum requirements), and then The Password Meter spits out your score on a 100-point scale. You also receive an assessment of the complexity of your password, with results ranging from weak to very strong. PasswordMeter.com will help you learn how to strengthen your password, because it reports how your password held up against various criteria used to judge password strength, such as number of characters, mix of letters/numbers/symbols, use of upper and lower case letters, etc.

“This application is designed to assess the strength of password strings. The instantaneous visual feedback provides the user a means to improve the strength of their passwords, with a hard focus on breaking the typical bad habits of faulty password formulation. Since no official weighting system exists, we created our own formulas to assess the overall strength of a given password. Please note, that this application does not utilize the typical ‘days-to-crack’ approach for strength determination. We have found that particular system to be severely lacking and unreliable for real-world scenarios. This application is neither perfect nor foolproof, and should only be utilized as a loose guide in determining methods for improving the password creation process.”

Web security is a common concern, and pretty much everyone who touches the Internet has at least one password-protected account somewhere on the web – so The Password Meter has a lot of potential users. The site is intuitive and there’s no registration requirements, both of which encourage new visitors to the site to give its service a try.

Don’t some websites already have a built-in password strength meter on the password creation page? How does this site plan to make a profit?
