An "ok" password manager is surely a feature Microsoft will add to Office 365, with a pro upgrade to shared passwords, etc

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.
