Good point. But since some of the best password managers are already open source, I wonder what's preventing browser vendors from integrating at least some of the functionality. A good password manager not only helps contain the damage of leaked passwords, but also does a very good job at protecting users from phishing attacks at similar-looking domains. All the browsers have been pretty stagnant on this front for the last few years. I suspect they've been hoping that everyone will move to an SSO platform in which the browser vendors themselves have a vested interest (Mozilla Persona, Google account, Microsoft account).
