Prevent user to find password through Firebug/Chrome Dev Tools

Question

For the passport input field:

Answer 1

Well , in 2019 there is a tricky way .. you can generate forms with JavaScript / jQuery over a div and you can put them on READ ONLY. If the attacker will disable JavaScript then the gen code will not work then will not be any form at well...

i already check this on xampp /windows 10 with firefox and changing with the inspector from type="password" to type="text" the script will "repair" again the things

in EDGE works buggy : when with Inspector i modify that stuff then all form is strip then inserted above html document
