> Why are passkeys better?

Passkeys provide perfect protection from phishing attacks, since it's impossible to send a passkey to the wrong domain. That's a huge improvement over TOTP.

Re: it being confusing where they're stored, I agree. The solution is to make sure you store your passkeys in your cross-platform password manager. The experience can be confusing though. In Chrome I've found that by default when creating a new Passkey Chrome offers to store it first. But if I click cancel, I'm then given the option to store it in 1Password where I want it.
