There is no password so it can't be a password manager. Without a password it avoids all the downsides of passwords like having to store them securely on both ends, rainbow tables, credential reuse, weak password choice, and having to remember them. It's a cryptographic keypair manager. Key management is always the barrier to really good real world cryptography, so I'm heartily in favour. Anything that makes it possible for regular people to use strong cryptography is a huge win.

Since it's all just FIDO2/webauthn under the hood it's hardly lockin. It's a bit of Apple UI tinsel to make life simple and their excellent icloud keychain sync.
