Show/Hide password on Registration Form

Hi,

How can I add a show/hide toggle for the password fields for the registration form at the Account Information section? Currently there is no way to see if you entered your chosen password incorrectly in the “Password” or “Confirm Password” fields until after you hit submit at checkout. If you have incorrectly inputted in one of the two fields, you are unaware of the unmatched passwords until the submit button is pressed at which time you’re sent back to correct it and your CC info is cleared and that has to be inputted again. Please advise.
