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]
How long would it take to crack your password [Naked Security, Sophos]
Passfault: an Open Source Tool for Measuring Password Complexity and Strength File:Artigo-Passfault.pdf
General Framework for Evaluating Password Complexity and Strength [Cornell University Library] "...This is something that has not been captured by any previous password strength or complexity measures, with the exception of [OWASP] Passfault"
- 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

- Partnet Inc. has donated paid labor on OWASP Passfault
- JetBrains has donated professional licenses for IntelliJ IDEA. If you are developing on OWASP Passfault contact the project leader and be sure to get a license!
- Join the OWASP Passfault Mailing list
- See the Roadmap
- Peruse the open issues
- Fork the code on github.
- If contribute significantly to the project contact the project leader for a professional license of IntelliJ IDEA by JetBrains (Thanks JetBrains!)
Goal: preparation for ESAPI
- More meaningful word lists
- Frequency lists: build lists of the most common words, names. (Done for English, Spainish)
- Improved configuration of finders and wordlists
- UI improvements
- Fix backlog of issues
- experiment with configuration of wordlists
Goals: Enterprise Ready - UI improvements for learning better password strategies - Easier to configure and run, not requiring a developer to wire things up.
Other Important Goals
- OS system integration:
- running passwd on linux runs passfault
- apt-get install passfault
- Document each pattern finder on the OWASP wiki.
- 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.
