Answer 1

You are setting the password strength on ALL password fields here: $(':password').pwstrength(options);

Change it to reference the ID of the specific field you want to use: $('#newPassword').pwstrength(options);

And in your HTML do this for your new password field:

<input id="newPassword" type="password />
