OWASP Passfault evaluates the strength of passwords accurately enough to predict the time to crack. It makes creating passwords and password policies significantly more intuitive and simple. Passwords don't have to be annoying!
OWASP Passfault is more ...
When setting a password, OWASP Passfault examines the password, looking for common patterns. It than measures the size of the patterns and combinations of patterns. The end result is a more academic and accurate measurement of password strength.
When setting a password policy, OWASP Passfault simplifies configuration to one simple meaningful measurement: the number of passwords found in the password patterns. This measurement is made more intuitive and meaningful with an estimated time to crack.

What is Passfault?
OWASP Passfault provides:
["Your Passwords don't Suck, its your Policies" - ZDNet] ["Redefining Password Strength and Creation" - MidsizeInsider, IBM] ["For Better Password Policies" - Turnlevel, Partnet] ["How long would it take to crack your password" - Naked Security, Sophos]
- Does the Demo Site capture or log passwords?
- No, of course not
- How can I be sure the Demo Site doesn't capture or log passwords?
- You can't, There is no way to verify what is uploaded to appspot (google is hosting the demo site) However, you can look at the code: https://github.com/c-a-m/passfault/blob/master/jsonService/src/main/java/org/owasp/passfault/web/PassfaultServlet.java We took the following steps to ensure the passwords don't get logged:
- GETs are blocked so no urls will have accidental passwords stored in the logs
- passwords are read directly from the input stream to prevent parsing into Java Strings
- the memory is cleared as soon as analysis is complete.
- HTTPS is required on this URL (using the appspot domain)
To be extra cautious, download the code and execute it locally. (See the readme) https://github.com/c-a-m/passfault/blob/master/README.txt
OWASP Passfault is developed by a worldwide team of volunteers. The primary contributors to date have been:
- Cam Morris
- University of Florida Students:
- Neeti Pathak
- Carlos Vasquez
- Chelsea Metcalf
- Yang Ou
- Partnet Inc. has donated paid labor on OWASP Passfault
- Document each pattern finder on the OWASP wiki.
- ESAPI Authenticator Decorator: Implement an ESAPI Authenticator that will enhance an existing authenticator with passfault implementing the "verifyPasswordStrength" method.
- A volunteer force from university of Florida has built this. All that remains is to get it into ESAPI.
- JQuery Plugin: A JQuery plugin that will let a web site use either the passfault applet or a passfault JSON Service to analyze a password.
- Wordlists: We can always use better word lists. Contact us on the mailing list if you want to help.
