In my opinion Safari is way too aggressive with filling usernames and passwords. Anything in any way similarly named like these it forces an autofill. And of course it overrides autocomplete="off". We definitely need an attribute that implies, "I actually know what I'm doing Safari! Please really don't autofill this."

Conversely, there are way too many websites that (intentionally or not) prevent password managers to function, which results in these kind of heuristics being implemented by password managers in order to be generally useful.

If that attribute existed, security audits would again force big enterprises to enable it to break auto fill on their password fields, taking us back to square one.
