Agreed on password fields, however if you have a webapp crm it causes so many problems. And also giving a solution of "hey just put something that we don't understand in the autocomplete so we won't try to autocomplete it" is really not a solution at all.

Imagine if instead of autocomplete it was something like ignoring font sizes/color because they detected that engagement was low when font size was whatever so they render it differently. A browser should render HTML not make decisions like these
