Right now, it seems like none of the big guys provide interoperability on their password managers by design. Apple's works great for apps and Safari, but won't work on Chrome, Google only works on Chrome, Microsoft's doesn't work on an iPhone.

an ok password manager is Chrome's password manager, isn't it?

It allows you to use smart unique passwords, syncs between devices, and uses the OS master key to hide the passwords.

It's not great, but it's probably good enough for many people.
