I just closed this Feature Request (with a delay of one month) as it seems to be implemented.
As @DenBesten already wrote, the browser extension has a setting for it (it’s similar in the new UI/UX). – On the Android mobile app, there is also a similar setting (in the Autofill section).
I can’t check the iOS app though, but I assume, the same function is also available on iOS.
If not, “ping” us to reopen this Feature Request. (and that’s why I also added a delay to the closing)
PS: All other apps are not relevant at this point in time, as only the browser extensions and mobile apps have autofill capability.
