Presently, it can be done by disabling "Autofill Passwords".
However, I want autofill passwords without the browser nagging me every time I login to a site whether I want to save the password.
There is a solution to disable it for the website by clicking "never for this site". But then, I cannot save password for that site in the future.
This is a bit annoying. As an alternative, show password icon in url bar on login which when clicked, the popup is shown (save, never save).
