It works well for me, you just need to synchronize your password manager's file once in a while. Are you really creating that many accounts ?
And you can use anything even cloud providers to easily synchronize the single file.
I don't use cloud password managers, history has shown it is too risky.
Which doesn't work well in a multi-devices landscape as the one we live in for many people (even if not the majority, because the majority probably just owns and uses a smartphone).
