Their "password manager" on Mac is called Keychain Access. The UX is very bad, the interface is old and clunky and it doesn't sync with iOS (if for example you create a secure note there's no way to access it on iOS) - not to mention that most people don't even know it exists, it's kind of a hidden feature. Meanwhile, on iOS the password manager is hidden in the settings and again it has pretty bad UI/UX. I understand that they want to hide the complexity away from the end user and make these kinds of features "just work", but in practice they feel pretty half-baked.
