Look at SQRL for a secure password managersystem that replaces a "password manager" with somethings that works without needing a central DB and can defeat the keyloggers as well. The web servers that you visit will not require secret state about you (like a password) with this system. The id that is provided to each website is unique for each website, so an id token from one site will not work with another.
The best "password manager" would be a system that doesn't require saving a bunch of hashes around the Internet.
