Hi 1P_Dave
I was able to force a password reset through the account's website and manually copy/paste a replacement password to make sure that the generator didn't auto-submit the page again.
I'd like to help more, but this may be tricky. It is the account setup page to a mortgage lender, and they require that you input some loan-specific information before you can create the account. This URL is probably as close as I'd be able to get you to their password creation page.
