Here's the tricky thing and I don't have a solution that doesn't get abused. I hate that lots of bank do this but I also have a use case for password autocomplete=off. We operate in an industry where shared computer access is very common and the risk of users saving password in browser is real and too high.

As I said don't know what the answer is. I definitely want someone using password manager be able to use them. Using a password manager is a conscious choice with setups involved. Browser's default autocomplete is often not. I don't know how to separate these two out.
