Password Strength Visualizer - Html & Javascript/Ajax

Question

I'm looking for a simple Password Strength Visualizer (like gmail's when you create a new account). I want to show the user how good their password is visually.

Does anyone have some source code they'd like to share? :)

Answer 1

Drupal has one built into Drupal 6. The code for the backport to Drupal 5 may be of use to you.

Answer 2

This one seems great: http://www.geekwisdom.com/dyn/passwdmeter.

Depending on the password score, you can show a green, yellow or red marker, or whatever you want.
