Password-protected site's sign-in button does nothing
What you are seeing
A password-protected site's sign-in button does nothing.
#Why it happens
Password sign-in needs JavaScript and modern browser crypto. With JavaScript off, the form cannot submit.

#What to do
Ask the visitor to enable JavaScript. A generic "Sign in failed. Please try again." alert is all the page can show on failure.
