Passkeys are in 1Password. I'm authenticated into 1Password on my phone, ipad, browser extension on multiple computers. As long as I don't lose access to all devices at the same time I'm fine...
Passkeys are arguably slightly more convenient and not risky for those of us who are technically aware enough to use password managers, sure. But that's not what most people will do. Most people will see their phone ask them to add fingerprint/face unlock, so they do that, and now their passkey is stored only on their phone (or in iCloud if they're lucky).
