Security is very important to all, and as such this page does NOT post, or transmit any password. The script does not require an active connection, so you can physically remove your internet connection before generating any passwords if concerned about security.

Valid Characters - The left column checkboxes are for specifying characters that are valid at the beginning of the password; the second column checkboxes specify characters that are valid for the rest of the password.

DISCLAIMER : 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.

Math.random() is used by the JavaScript on this page to generate the passwords, and it can be argued that is not a cryptographically secure pseudorandom number generator. Use at your own risk.
