The pick if privacy is the priority. Proton Pass comes from the maker of Proton Mail, is open source and end-to-end encrypted, and includes hide-my-email aliases so you can hand out a different address to every site. A capable free tier makes it easy to start.
It is newer than the incumbents, so a few advanced features are still catching up, but if you already use Proton's mail or VPN it folds neatly into one subscription and one trusted company.
