> I feel I can take a password and print it on paper, memorize it, save it on a USB stick, tell it to my wife. I feel in control with passwords. Nobody owns them but me.

But reality is exactly the opposite: You don't own your passwords. You hand it out freely to sites you create an account with, and rely on those sites to store the passwords securely. Many don't; either way, you don't know. Regularly, sites get breached and millions of passwords—including yours—are published. That is the least form of control over credentials I can imagine, lest yourself publishing it online.

Passkeys alleviate this by creating an account/site scoped key pair, and only handing out the public key to the site. Breaching a Passkey-only service is futile, because those public keys don't work anywhere else by design. The only one in possession of the private keys is you; compared to passwords, that's infinitely more control.

> Passkeys feel like a wild wild WILD west of providers and islands and standards.

I don't quite understand why you feel that way; there's a single, open, freely accessible specification, implemented by more and more vendors.

> It feels like if I sign up to a website on my iPhone creating a pass key, it is a nontrivial amount of work and even less trivial amount of knowledge to transfer it to my android tablet or windows pc. Or maybe that's not even a thing and really I need to resign up on those devices? Or i need to authenticate a second device with my first one? So if I sign up to website 1 with my phone and website 2 with my tablet and website 3 with my laptop,if I want to access all of those from all my devices, I now have a fun weekend of syncing or something?

Ideally, you would sign into the service with separate Passkeys per device. A mechanism many sites implement is that you can sign in on a new device by letting the browser show a QR code that you can scan with a previously authenticated device to complete the authentication process. It's really straightforward. And if you don't want that for some reason, you can usually choose to send an OTP to your email or phone and use that for the initial signin, then register a new Passkey for the new device.

I totally see how the burden of making it user-friendly is on the particular site here, and the instruction quality varies between vendors—but that isn't on the technology itself.

If you don't trust Apple, install a password manager like 1Password on her devices and let its browser extension handle the complexity. Source: My mother.

> More than anything, you prove my and disprove gp's point that passwords are not necessarily always going to be an option for all sites and services. In fact it feels everybody is yelling in my face that passwords are gone and this half baked complex system will be the only thing.

I'm sure you're an intelligent individual and would really encourage just reading up on Passkeys and the problem's they're actually solving. Passwords should be gone for a variety of reasons, and Passkeys are superior. While I do see how communication around Passkeys was sub-par, I don't think there can be doubt in how asymmetric cryptography is better than passwords in terms of security and usability, if done properly.
