That seems incredibly low. Using Firefox's built-in password manager I definitely get >90% of sites. The only site that I use frequently where it doesn't work is my bank because the "card number" isn't recognized as the username. But even copy-paste isn't too difficult. Roughly as much clicking as the magic-link solution in my experience.
