which line of code to change the text "Pre Shared Key" to "Password" in index.html file

Hi I looked around and saw that in 2017 @mcocigra answered this question and stated that relevant line was 162 iI had a look around and used ctrl+w to search for the key words "Pre Shared Key" but I cant find anything.Has anybody else managed to do this?Im no expert but it seems the string has now been placed in a variable which i dont know how to modify... anybody?
