Microsoft's new password collector.
Sorry, did I say that out loud?
No, it's not really a password collector.
What I'm talking about is a new tool from Microsoft that aims to tell you when a password is "Weak", "Medium", "Strong" or "Best".
Try it for yourself - see that "This is my password." is "BEST", and "Cz!r4Tz" is "Weak".
From that comparison, it's obvious that this tool is only a guideline, and probably that's all it can be - but you might want to try it on your users. At the very least, many weak passwords will be shown to them as being weak.
