Password confirmations aren't really there for security. More as a sanity check to make sure the user hasn't accidentally typed their password incorrectly.
Well, I mean the starred out password fields. Why have them in the first place? Why not just have a password field that acts like any other text field, showing you what you've typed. Seeing this elaborate color based password match plugin kind of speaks to the absurdity of it.

* Extremely confusing to users
