offers Quest One(tm) Password Manager for $5/user.

To use the web application you need to know your domain, username, and
the value of the presented captcha. You submit that, correctly, and the
web application will present you with the user's full name and some

actually know the value of the captcha. Someone who is really bored

outsourced your helpdesk too, which means you're about to get pwn3d via
some fairly lame social engineering. Enjoy that.
