Stop LastPass filling out a form
Two conditions have to be met:
- The form (not the element) needs to have
autocomplete="off"
attribute - Lastpass user needs to have this option enabled:
- (old)
Settings > Advanced > Allow pages to disable autofill
- (new)
Account Options > Extension Preferences > Advanced > Respect AutoComplete=off: allow websites to disable Autofill
- (old)
So this depends on both user and the developer.
Adding
data-lpignore="true"
to an input field disabled the grey LastPass [...] box for me.
